Accounting Policies [Abstract]
General	(1) GENERAL Basis of Presentation The accompanying condensed consolidated financial statements of Skechers U.S.A., Inc. (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”), for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S‑X. Accordingly, they do not include certain notes and financial presentations normally required under U.S. GAAP for complete financial reporting. The interim financial information is unaudited, but reflects all normal adjustments and accruals which are, in the opinion of management, considered necessary to provide a fair presentation for the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The results of operations for the six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the entire fiscal year ending December 31, 2018. Inventories Inventories, principally finished goods, are stated at the lower of cost (based on the first-in, first-out method) or market (net realizable value). Cost includes shipping and handling fees and costs, which are subsequently expensed to cost of sales. The Company provides for estimated losses from obsolete or slow-moving inventories, and writes down the cost of inventory at the time such determinations are made. Reserves are estimated based on inventory on hand, historical sales activity, industry trends, the retail environment, and the expected net realizable value. The net realizable value is determined using estimated sales prices of similar inventory through off-price or discount store channels. Fair Value of Financial Instruments The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This accounting standard established a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required: • Level 1 – Quoted prices in active markets for identical assets or liabilities. The Company’s Level 1 non-derivative investments primarily include money market funds and actively traded mutual funds. • Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 non-derivative investments primarily include corporate notes and bonds. The Company has one Level 2 derivative which is an interest rate swap related to the refinancing of its domestic distribution center (see below). • Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. The Company currently does not have any Level 3 assets or liabilities. The carrying amount of the Company’s financial instruments, which principally include cash and cash equivalents, short-term investments, accounts receivable, long-term investments, accounts payable and accrued expenses approximates fair value because of the relatively short maturity of such instruments. The carrying amount of the Company’s short-term and long-term borrowings, which are considered Level 2 liabilities, approximates fair value based upon current rates and terms available to the Company for similar debt. As of August 12, 2015, the Company entered into an interest rate swap agreement concurrent with refinancing its domestic distribution center construction loan (see Note 3). The fair value of the interest rate swap was determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipt was based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with U.S. GAAP, credit valuation adjustments were incorporated to appropriately reflect both the Company’s nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. The majority of the inputs used to value the interest rate swap were within Level 2 of the fair value hierarchy. As of June 30, 2018 and December 31, 2017, the interest rate swap was a Level 2 derivative and HF Logistics is responsible for any amounts related to the interest rate swap agreement. Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates. Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to its customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company derives income from the sale of footwear and royalties earned from licensing the Skechers brand. For North America, goods are shipped Free on Board (“FOB”) shipping point directly from the Company’s domestic distribution center in Rancho Belago, California. For international wholesale customers product is shipped FOB shipping point, (i) direct from the Company’s distribution center in Liege, Belgium, (ii) to third-party distribution centers in Central America, South America and Asia, (iii) directly from third-party manufacturers to our other international customers. For our distributor sales, the goods are generally delivered directly from the independent factories to third-party distribution centers or to our distributors’ freight forwarders on a Free Named Carrier (“FCA”) basis. The Company recognizes revenue on wholesale sales upon shipment as that is when the customer obtains control of the promised goods. are accounted for as a fulfillment cost and not as a separate performance obligation. The Company records accounts receivable at the time of shipment when the Company’s right to the consideration becomes unconditional. The Company typically extends credit terms to our wholesale customers based on their creditworthiness and generally does not receive advance payments. Generally, wholesale customers do not have the right to return goods, however, the Company periodically decides to accept returns or provide customers with credits. Allowances for estimated returns, discounts, doubtful accounts and chargebacks are provided for when related revenue is recorded. Retail and e-commerce sales represent amounts due from credit card companies and are generally collected within a few days of the purchase. As such, the Company has determined that no allowance for doubtful accounts is necessary. The Company earns royalty income from its licensing arrangements which qualify as symbolic licenses rather than functional licenses. Upon signing a new licensing agreement, we receive up-front fees, which are generally characterized as prepaid royalties. These fees are initially deferred and recognized as revenue as earned (i.e., as licensed sales are reported to the Company or on a straight-line basis over the term of the agreement). The first calculated royalty payment is based on actual sales of the licensed product or, in some cases, minimum royalty payments. The Company calculates and accrues estimated royalties based on the agreement terms and correspondence with the licensees regarding actual sales. Judgments The Company considered several factors in determining that control transfers to the customer upon shipment of products. These factors include that legal title transfers to the customer, the Company has a present right to payment, and the customer has assumed the risks and rewards of ownership at the time of shipment. The Company accrues a reserve for product returns at the time of sale based on our historical experience. The Company also accrues amounts for goods expected to be returned in salable condition. As of June 30, 2018 and December 31, 2017, the Company’s sales returns reserve totaled $40.9 million and $43.4 million, respectively, and was included in other accrued liabilities and accounts receivable in the condensed consolidated balance sheet, respectively. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “ Revenue from Contracts with Customers Revenue from Contracts with Customers Revenue Recognition These ASU’s also require enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and cash flows. In October 2016, the FASB issued ASU No. 2016-16, “ Accounting for Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory In February 2016, the FASB issued ASU No. 2016-02, “ Leases (Topic 842) In February 2018, the FASB issued ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”

The maturities of the Company’s long-term investments are typically less than two years. The Company considers the declines in market value of its marketable securities investment portfolio to be temporary in nature. The Company typically invests in highly-rated securities, and its investment policy generally limits the amount of credit exposure to any one issuer. The policy generally requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss. Fair values were determined for each individual security in the investment portfolio. When evaluating an investment for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. As of June 30, 2018, the Company does not consider any of its investments to be other-than-temporarily impaired.

The Company is in compliance with its non-financial covenants, including any cross-default provisions and financial covenants of its long-term borrowings as of June 30, 2018. On June 30, 2015, the Company entered into a $250.0 million loan and security agreement, subject to increase by up to $100.0 million, (the “Credit Agreement”), with the following lenders: Bank of America, N.A., MUFG Union Bank, N.A. and HSBC Bank USA, National Association. The Credit Agreement matures on June 30, 2020. The Credit Agreement replaces the credit agreement dated June 30, 2009, which expired on June 30, 2015. The Credit Agreement permits the Company and certain of its subsidiaries to borrow based on a percentage of eligible accounts receivable plus the sum of (a) the lesser of (i) a percentage of eligible inventory to be sold at wholesale and (ii) a percentage of net orderly liquidation value of eligible inventory to be sold at wholesale, plus (b) the lesser of (i) a percentage of the value of eligible inventory to be sold at retail and (ii) a percentage of net orderly liquidation value of eligible inventory to be sold at retail, plus (c) the lesser of (i) a percentage of the value of eligible in-transit inventory and (ii) a percentage of the net orderly liquidation value of eligible in-transit inventory. Borrowings bear interest at the Company’s election based on (a) LIBOR or (b) the greater of (i) the Prime Rate, (ii) the Federal Funds Rate plus 0.5% and (iii) LIBOR for a 30-day period plus 1.0%, in each case, plus an applicable margin based on the average daily principal balance of revolving loans available under the Credit Agreement. The Company pays a monthly unused line of credit fee of 0.25%, payable on the first day of each month in arrears, which is based on the average daily principal balance of outstanding revolving loans and undrawn amounts of letters of credit outstanding during such month. The Credit Agreement further provides for a limit on the issuance of letters of credit to a maximum of $100.0 million. The Credit Agreement contains customary affirmative and negative covenants for secured credit facilities of this type, including covenants that will limit the ability of the Company and its subsidiaries to, among other things, incur debt, grant liens, make certain acquisitions, dispose of assets, effect a change of control of the Company, make certain restricted payments including certain dividends and stock redemptions, make certain investments or loans, enter into certain transactions with affiliates and certain prohibited uses of proceeds. The Credit Agreement also requires compliance with a minimum fixed-charge coverage ratio if Availability drops below 10% of the Revolver Commitments (as such terms are defined in the Credit Agreement) until the date when no event of default has existed and Availability has been over 10% for 30 consecutive days. The Company paid closing and arrangement fees of $1.1 million on this facility which are included in other assets in the condensed consolidated balance sheets, and are being amortized to interest expense over the five-year life of the facility. As of June 30, 2018 and December 31, 2017, there was $0.1 million outstanding under the Company’s credit facilities, classified as short-term borrowings in the Company’s condensed consolidated balance sheets. The remaining balance in short-term borrowings, as of June 30, 2018, is related to the Company’s international operations. On April 30, 2010, HF Logistics-SKX, LLC (the “JV”), through its subsidiary HF-T1, entered into a construction loan agreement with Bank of America, N.A., as administrative agent and as a lender, and Raymond James Bank, FSB, as a lender (collectively, the "Construction Loan Agreement"), pursuant to which the JV obtained a loan of up to $55.0 million used for construction of the project on certain property (the "Original Loan"). On November 16, 2012, HF-T1 executed a modification to the Construction Loan Agreement (the "Modification"), which added OneWest Bank, FSB as a lender, and increased the borrowings under the Original Loan to $80.0 million and extended the maturity date of the Original Loan to October 30, 2015. On August 11, 2015, the JV, through HF-T1, entered into an amended and restated loan agreement with Bank of America, N.A., as administrative agent and as a lender, and CIT Bank, N.A. (formerly known as OneWest Bank, FSB) and Raymond James Bank, N.A., as lenders (collectively, the "Amended Loan Agreement"), which amends and restates in its entirety the Construction Loan Agreement and the Modification. As of the date of the Amended Loan Agreement, the outstanding principal balance of the Original Loan was $77.3 million. In connection with this refinancing of the Original Loan, the JV, the Company and its joint-venture partner HF Logistics (“HF”) agreed that the Company would make an additional capital contribution of $38.7 million to the JV, through HF-T1, to make a prepayment on the Original Loan based on the Company’s 50% equity interest in the JV. The prepayment equaled the Company’s 50% share of the outstanding principal balance of the Original Loan. Under the Amended Loan Agreement, the parties agreed that the lenders would loan $70.0 million to HF-T1 (the "New Loan"). The New Loan was used by the JV, through HF-T1, to (i) refinance all amounts owed on the Original Loan after taking into account the prepayment described above, (ii) pay $0.9 million in accrued interest, loan fees and other closing costs associated with the New Loan and (iii) make a distribution of $31.3 million less the amounts described in clause (ii) to HF. Pursuant to the Amended Loan Agreement, the interest rate on the New Loan is the LIBOR Daily Floating Rate (as defined in the Amended Loan Agreement) plus a margin of 2%. The maturity date of the New Loan is August 12, 2020, which HF-T1 has one option to extend by an additional 24 months, or until August 12, 2022, upon payment of a fee and satisfaction of certain customary conditions. On August 11, 2015, HF-T1 and Bank of America, N.A. entered into an ISDA Master Agreement (together with the schedule related thereto, the "Swap Agreement") to govern derivative and/or hedging transactions that HF-T1 concurrently entered into with Bank of America, N.A. Pursuant to the Swap Agreement, on August 14, 2015, HF-T1 entered into a confirmation of swap transactions (the "Interest Rate Swap") with Bank of America, N.A. The Interest Rate Swap has an effective date of August 12, 2015 and a maturity date of August 12, 2022, subject to early termination at the option of HF-T1, commencing on August 1, 2020. The Interest Rate Swap fixes the effective interest rate of the New Loan at 4.08% per annum. Pursuant to the terms of the JV, HF is responsible for the related interest expense payments on the New Loan, and any amounts related to the Swap Agreement. The full amount of interest expense paid related to the New Loan has been included in the Company’s consolidated statement of equity within non-controlling interests. The Amended Loan Agreement and the Swap Agreement are subject to customary covenants and events of default. Bank of America, N.A. also acts as a lender and syndication agent under the Credit Agreement dated June 30, 2015.

Noncontrolling Interest [Abstract]
Non-Controlling Interests	(4) NON-CONTROLLING INTERESTS The Company has equity interests in several joint ventures that were established either to exclusively distribute the Company’s products primarily throughout Asia or to construct the Company’s domestic distribution facility. These joint ventures are variable interest entities (“VIEs”) under ASC 810-10-15-14. The Company’s determination of the primary beneficiary of a VIE considers all relationships between the Company and the VIE, including management agreements, governance documents and other contractual arrangements. The Company has determined for its VIEs that the Company is the primary beneficiary because it has both of the following characteristics: (a) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance, and (b) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Accordingly, the Company includes the assets and liabilities and results of operations of these entities in its condensed consolidated financial statements, even though the Company may not hold a majority equity interest. There have been no changes during 2018 in the accounting treatment or characterization of any previously identified VIE. The Company continues to reassess these relationships quarterly. The assets of these joint ventures are restricted in that they are not available for general business use outside the context of such joint ventures. The holders of the liabilities of each joint venture have no recourse to the Company. The Company does not have a variable interest in any unconsolidated VIEs. The following VIEs are consolidated into the Company’s condensed consolidated financial statements and the carrying amounts and classification of assets and liabilities were as follows (in thousands): HF Logistics-SKX, LLC June 30, 2018 December 31, 2017 Current assets $ 1,170 $ 1,540 Non-current assets 100,777 103,407 Total assets $ 101,947 $ 104,947 Current liabilities $ 2,802 $ 2,718 Non-current liabilities 65,459 66,367 Total liabilities $ 68,261 $ 69,085 Distribution joint ventures (1) June 30, 2018 December 31, 2017 Current assets $ 484,691 $ 389,687 Non-current assets 92,980 90,972 Total assets $ 577,671 $ 480,659 Current liabilities $ 237,490 $ 188,700 Non-current liabilities 5,714 9,201 Total liabilities $ 243,204 $ 197,901 _____________________ (1) Distribution joint ventures include Skechers Footwear Ltd.

Earnings Per Share [Abstract]
Earnings Per Share	(7) EARNINGS PER SHARE Basic earnings per share represent net earnings divided by the weighted average number of common shares outstanding for the period. Diluted earnings per share, in addition to the weighted average determined for basic earnings per share, includes potential dilutive common shares using the treasury stock method. The Company has two classes of issued and outstanding common stock: Class A Common Stock and Class B Common Stock. Holders of Class A Common Stock and holders of Class B Common Stock have substantially identical rights, including rights with respect to any declared dividends or distributions of cash or property and the right to receive proceeds on liquidation or dissolution of the Company after payment of the Company’s indebtedness. The two classes have different voting rights, with holders of Class A Common Stock entitled to one vote per share while holders of Class B Common Stock are entitled to ten votes per share on all matters submitted to a vote of stockholders. The Company uses the two-class method for calculating net earnings per share. Basic and diluted net earnings per share of Class A Common Stock and Class B Common Stock are identical. The shares of Class B Common Stock are convertible at any time at the option of the holder into shares of Class A Common Stock on a share-for-share basis. In addition, shares of Class B Common Stock will be automatically converted into a like number of shares of Class A Common Stock upon transfer to any person or entity who is not a permitted transferee. The following is a reconciliation of net earnings and weighted average common shares outstanding for purposes of calculating basic earnings per share (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, Basic earnings per share 2018 2017 2018 2017 Net earnings attributable to Skechers U.S.A., Inc. $ 45,284 $ 59,535 $ 162,936 $ 153,530 Weighted average common shares outstanding 156,518 155,579 156,476 155,340 Basic earnings per share attributable to Skechers U.S.A., Inc. $ 0.29 $ 0.38 $ 1.04 $ 0.99 The following is a reconciliation of net earnings and weighted average common shares outstanding for purposes of calculating diluted earnings per share (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, Diluted earnings per share 2018 2017 2018 2017 Net earnings attributable to Skechers U.S.A., Inc. $ 45,284 $ 59,535 $ 162,936 $ 153,530 Weighted average common shares outstanding 156,518 155,579 156,476 155,340 Dilutive effect of nonvested shares 573 595 890 676 Weighted average common shares outstanding 157,091 156,174 157,366 156,016 Diluted earnings per share attributable to Skechers U.S.A., Inc. $ 0.29 $ 0.38 $ 1.04 $ 0.98 There were 195,041 shares excluded from the computation of diluted earnings per share for the three and six months ended June 30, 2018 because they are antidilutive.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Compensation	(8) STOCK COMPENSATION (a) Incentive Award Plan On April 17, 2017, the Company’s Board of Directors adopted the 2017 Incentive Award Plan (the “2017 Plan”), which became effective upon approval by the Company’s stockholders on May 23, 2017. The 2017 Plan replaced and superseded in its entirety the 2007 Incentive Award Plan (the “2007 Plan”), which expired pursuant to its terms on May 24, 2017. A total of 10,000,000 shares of Class A Common Stock are reserved for issuance under the 2017 Plan, which provides for grants of ISOs, non-qualified stock options, restricted stock and various other types of equity awards as described in the plan to the employees, consultants and directors of the Company and its subsidiaries. The 2017 Plan is administered by the Company’s Board of Directors with respect to awards to non-employee directors and by the Company’s Compensation Committee with respect to other eligible participants. For stock-based awards, the Company recognized compensation expense based on the grant date fair value. Share‑based compensation expense was $7.3 million and $7.6 million for the three months ended June 30, 2018 and 2017, respectively. Share-based compensation expense was $16.0 million and $14.2 million for the six months ended June 30, 2018 and 2017, respectively. During the three and six months ended June 30, 2018, the Company redeemed 87,326 and 300,256 shares of Class A Common Stock for $2.5 million and $11.2 million to satisfy employee tax withholding requirements. No shares were redeemed during the three and six months ended June 30, 2017. A summary of the status and changes of the Company’s nonvested shares related to the 2007 Plan and the 2017 Plan, as of and for the six months ended June 30, 2018 is presented below: Shares Weighted Average Grant-Date Fair Value Nonvested at December 31, 2017 2,303,557 $ 26.25 Granted 1,637,500 39.00 Vested (797,075 ) 22.53 Cancelled (117,333 ) 30.46 Nonvested at June 30, 2018 3,026,649 33.96 As of June 30, 2018, there was $84.8 million of unrecognized compensation cost related to nonvested common shares. The cost is expected to be amortized over a weighted average period of 2.9 years. (b) Stock Purchase Plan On April 17, 2017, the Company’s Board of Directors adopted the 2018 Employee Stock Purchase Plan (the “2018 ESPP”), which the Company’s stockholders approved on May 23, 2017. The 2018 Employee Stock Purchase Plan provides eligible employees of the Company and its subsidiaries with the opportunity to purchase shares of the Company’s Class A Common Stock at a purchase price equal to 85% of the Class A Common Stock’s fair market value on the first trading day or last trading day of each purchase period, whichever is lower. The 2018 ESPP generally provides for two six-month purchase periods every twelve months: June 1 through November 30 and December 1 through May 31, except that the initial purchase period under the 2018 ESPP will have a duration of five months, commencing on January 1, 2018 and ending on May 31, 2018. Eligible employees participating in the 2018 ESPP will, for a purchase period, be able to invest up to 15% of their compensation through payroll deductions during each purchase period. A total of 5,000,000 shares of Class A Common Stock are available for issuance under the 2018 ESPP.

Income Tax Disclosure [Abstract]
Income Taxes	(9) INCOME TAXES Income tax expense and the effective tax rate for the three and six months ended June 30, 2018 and 2017 were as follows (dollar amounts in thousands): Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Income tax expense $ 14,080 $ 14,109 $ 28,700 $ 31,516 Effective tax rate 18.8 % 16.1 % 12.7 % 14.9 % The tax provisions for the three and six months ended June 30, 2018 and 2017 were computed using the estimated effective tax rates applicable to each of the domestic and international taxable jurisdictions for the full year. The Company estimates its effective tax rate for remainder of 2018 to be at the top of or slightly higher than the 12% to 17% range previously provided. The Company’s tax rate is subject to management’s quarterly review and revision, as necessary. The Company’s provision for income tax expense and effective income tax rate are significantly impacted by the mix of the Company’s domestic and foreign earnings (loss) before income taxes. In the foreign jurisdictions in which the Company has operations, the applicable statutory rates range from 0% to 34%, which is on average significantly lower than the U.S. federal and state combined statutory rate of approximately 26%. Due to the enactment of Tax Cuts and Jobs Act (“the Tax Act”) in December 2017, the Company is subject to a tax on global intangible low-taxed income (“GILTI”). GILTI is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. Companies subject to GILTI have the option to account for the GILTI tax as a period cost if and when incurred, or to recognize deferred taxes for temporary differences including outside basis differences expected to reverse as GILTI. The Company has elected to account for GILTI as a period cost, and therefore has included GILTI expense in its effective tax rate calculation for the three and six months ended June 30, 2018. The U.S. Securities and Exchange Commission For the three months ended June 30, 2018, the increase in the effective tax rate was due to decreases in certain foreign deferred tax assets and increased U.S. tax on foreign earnings resulting from changes in U.S. tax law under the Tax Act. For the six months ended June 30, 2018, the decrease in rate was primarily due to an $8.0 million reduction in the Company’s accounting for certain tax effects of the Tax Act, and an increase of $1.6 million in excess tax benefits under ASU 2016-09. As of June 30, 2018, the Company had approximately $844.8 million in cash and cash equivalents, of which $375.9 million, or 44.5%, was held outside the U.S. Of the $375.9 million held by the Company’s non-U.S. subsidiaries, approximately $176.9 million is available for repatriation to the U.S. without incurring U.S. income taxes and applicable non-U.S. income and withholding taxes in excess of the amounts accrued in the Company’s condensed consolidated financial statements as of June 30, 2018. The Company’s cash and cash equivalents held in the U.S. and cash provided from operations are sufficient to meet the Company’s liquidity needs in the U.S. for the next twelve months. However, in anticipation of the needs of the Company’s share repurchase program and the need to provide payment of the Company’s provisional Transition Tax liability, the Company may repatriate certain funds held outside the U.S. for which all applicable U.S. and non-U.S. tax has been fully provided as of June 30, 2018. Because of the need for cash for operating capital and continued overseas expansion, the Company also does not foresee the need for any of its foreign subsidiaries to distribute funds up to an intermediate foreign parent company in any form of taxable dividend. Under current applicable tax laws, if the Company chooses to repatriate some or all of the funds the Company has designated as indefinitely reinvested outside the U.S., the amount repatriated would not be subject to U.S. income taxes but may be subject to applicable non-U.S. income and withholding taxes.

Risks And Uncertainties [Abstract]
Business and Credit Concentrations	(10) BUSINESS AND CREDIT CONCENTRATIONS The Company generates sales in the United States; however, several of its products are sold into various foreign countries, which subjects the Company to the risks of doing business abroad. In addition, the Company operates in the footwear industry, and its business depends on the general economic environment and levels of consumer spending. Changes in the marketplace may significantly affect management’s estimates and the Company’s performance. Management performs regular evaluations concerning the ability of customers to satisfy their obligations and provides for estimated doubtful accounts. Domestic accounts receivable, which generally do not require collateral from customers, were $258.2 million and $206.1 million before allowances for bad debts, sales returns and chargebacks at June 30, 2018 and December 31, 2017, respectively. Foreign accounts receivable, which in some cases are collateralized by letters of credit, were $313.4 million and $251.0 million before allowance for bad debts, sales returns and chargebacks at June 30, 2018 and December 31, 2017, respectively. The Company’s credit losses attributable to write-offs for the three months ended June 30, 2018 and 2017 were $2.2 million and $2.1 million, respectively. Assets located outside the U.S. consist primarily of cash, accounts receivable, inventory, property, plant and equipment, and other assets. Net assets held outside the United States were $1.381 billion and $1.273 billion at June 30, 2018 and December 31, 2017, respectively. The Company’s net sales to its five largest customers accounted for approximately 11.2% and 14.0% of total net sales for the three months ended June 30, 2018 and 2017, respectively. The Company’s top five manufacturers produced the following, as a percentage of total production, for the three and six months ended June 30, 2018 and 2017: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Manufacturer #1 11.2 % 20.0 % 12.1 % 21.1 % Manufacturer #2 9.0 % 11.0 % 11.5 % 11.0 % Manufacturer #3 8.8 % 8.1 % 8.7 % 8.6 % Manufacturer #4 5.8 % 6.3 % 5.9 % 6.0 % Manufacturer #5 5.1 % 6.2 % 5.0 % 5.0 % 39.9 % 51.6 % 43.2 % 51.7 % The majority of the Company’s products are produced in China and Vietnam. The Company’s operations are subject to the customary risks of doing business abroad, including, but not limited to, currency fluctuations and revaluations, custom duties, tariffs and related fees, various import controls and other monetary barriers, restrictions on the transfer of funds, labor unrest and strikes, and, in certain parts of the world, political instability. The Company believes it has acted to reduce these risks by diversifying manufacturing among various factories. To date, these business risks have not had a material adverse impact on the Company’s operations.

The Company has joint ventures in Asia that generate net sales from those regions. The Company also has a subsidiary in Switzerland that generates net sales from that country in addition to net sales to distributors located in numerous non-European countries. External net sales are attributable to geographic regions based on the location of each of the Company’s subsidiaries. A subsidiary may earn revenue from external net sales and external royalties, or from inter-subsidiary net sales, royalties, fees and commissions provided in accordance with certain inter-subsidiary agreements. The resulting earnings of each subsidiary in its respective country are recognized under each respective country’s tax code. Inter-subsidiary revenues and expenses subsequently are eliminated in the Company’s condensed consolidated financial statements and are not included as part of the external net sales reported in different geographic areas. (2) Other international includes Asia, Central America, Europe, the Middle East, and South America. In response to the State Department’s trade restrictions with Sudan and Syria, we do not authorize or permit any distribution or sales of our product in these countries, and we are not aware of any current or past distribution or sales of our product in Sudan or Syria.

Litigation

Commitments And Contingencies Disclosure [Abstract]
Litigation	(13) LITIGATION In accordance with U.S. GAAP, the Company records a liability in its condensed consolidated financial statements for loss contingencies when a loss is known or considered probable and the amount can be reasonably estimated. When determining the estimated loss or range of loss, significant judgment is required to estimate the amount and timing of a loss to be recorded. Estimates of probable losses resulting from litigation and governmental proceedings are inherently difficult to predict, particularly when the matters are in the procedural stages or with unspecified or indeterminate claims for damages, potential penalties, or fines. Accordingly, the Company cannot determine the final amount, if any, of its liability beyond the amount accrued in the condensed consolidated financial statements as of June 30, 2018, nor is it possible to estimate what litigation-related costs will be in the future; however, the Company believes that the likelihood that claims related to litigation would result in a material loss to the Company, either individually or in the aggregate, is remote.

The interim financial information is unaudited, but reflects all normal adjustments and accruals which are, in the opinion of management, considered necessary to provide a fair presentation for the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017. The results of operations for the six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the entire fiscal year ending December 31, 2018.
Inventories	Inventories Inventories, principally finished goods, are stated at the lower of cost (based on the first-in, first-out method) or market (net realizable value). Cost includes shipping and handling fees and costs, which are subsequently expensed to cost of sales. The Company provides for estimated losses from obsolete or slow-moving inventories, and writes down the cost of inventory at the time such determinations are made. Reserves are estimated based on inventory on hand, historical sales activity, industry trends, the retail environment, and the expected net realizable value. The net realizable value is determined using estimated sales prices of similar inventory through off-price or discount store channels.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This accounting standard established a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required: • Level 1 – Quoted prices in active markets for identical assets or liabilities. The Company’s Level 1 non-derivative investments primarily include money market funds and actively traded mutual funds. • Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 non-derivative investments primarily include corporate notes and bonds. The Company has one Level 2 derivative which is an interest rate swap related to the refinancing of its domestic distribution center (see below). • Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. The Company currently does not have any Level 3 assets or liabilities. The carrying amount of the Company’s financial instruments, which principally include cash and cash equivalents, short-term investments, accounts receivable, long-term investments, accounts payable and accrued expenses approximates fair value because of the relatively short maturity of such instruments. The carrying amount of the Company’s short-term and long-term borrowings, which are considered Level 2 liabilities, approximates fair value based upon current rates and terms available to the Company for similar debt. As of August 12, 2015, the Company entered into an interest rate swap agreement concurrent with refinancing its domestic distribution center construction loan (see Note 3). The fair value of the interest rate swap was determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipt was based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with U.S. GAAP, credit valuation adjustments were incorporated to appropriately reflect both the Company’s nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. The majority of the inputs used to value the interest rate swap were within Level 2 of the fair value hierarchy. As of June 30, 2018 and December 31, 2017, the interest rate swap was a Level 2 derivative and HF Logistics is responsible for any amounts related to the interest rate swap agreement.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to its customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company derives income from the sale of footwear and royalties earned from licensing the Skechers brand. For North America, goods are shipped Free on Board (“FOB”) shipping point directly from the Company’s domestic distribution center in Rancho Belago, California. For international wholesale customers product is shipped FOB shipping point, (i) direct from the Company’s distribution center in Liege, Belgium, (ii) to third-party distribution centers in Central America, South America and Asia, (iii) directly from third-party manufacturers to our other international customers. For our distributor sales, the goods are generally delivered directly from the independent factories to third-party distribution centers or to our distributors’ freight forwarders on a Free Named Carrier (“FCA”) basis. The Company recognizes revenue on wholesale sales upon shipment as that is when the customer obtains control of the promised goods. are accounted for as a fulfillment cost and not as a separate performance obligation. The Company records accounts receivable at the time of shipment when the Company’s right to the consideration becomes unconditional. The Company typically extends credit terms to our wholesale customers based on their creditworthiness and generally does not receive advance payments. Generally, wholesale customers do not have the right to return goods, however, the Company periodically decides to accept returns or provide customers with credits. Allowances for estimated returns, discounts, doubtful accounts and chargebacks are provided for when related revenue is recorded. Retail and e-commerce sales represent amounts due from credit card companies and are generally collected within a few days of the purchase. As such, the Company has determined that no allowance for doubtful accounts is necessary. The Company earns royalty income from its licensing arrangements which qualify as symbolic licenses rather than functional licenses. Upon signing a new licensing agreement, we receive up-front fees, which are generally characterized as prepaid royalties. These fees are initially deferred and recognized as revenue as earned (i.e., as licensed sales are reported to the Company or on a straight-line basis over the term of the agreement). The first calculated royalty payment is based on actual sales of the licensed product or, in some cases, minimum royalty payments. The Company calculates and accrues estimated royalties based on the agreement terms and correspondence with the licensees regarding actual sales. Judgments The Company considered several factors in determining that control transfers to the customer upon shipment of products. These factors include that legal title transfers to the customer, the Company has a present right to payment, and the customer has assumed the risks and rewards of ownership at the time of shipment. The Company accrues a reserve for product returns at the time of sale based on our historical experience. The Company also accrues amounts for goods expected to be returned in salable condition. As of June 30, 2018 and December 31, 2017, the Company’s sales returns reserve totaled $40.9 million and $43.4 million, respectively, and was included in other accrued liabilities and accounts receivable in the condensed consolidated balance sheet, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 “ Revenue from Contracts with Customers Revenue from Contracts with Customers Revenue Recognition These ASU’s also require enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and cash flows. In October 2016, the FASB issued ASU No. 2016-16, “ Accounting for Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory In February 2016, the FASB issued ASU No. 2016-02, “ Leases (Topic 842) In February 2018, the FASB issued ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”
Non-Controlling Interests	NON-CONTROLLING INTERESTS The Company has equity interests in several joint ventures that were established either to exclusively distribute the Company’s products primarily throughout Asia or to construct the Company’s domestic distribution facility. These joint ventures are variable interest entities (“VIEs”) under ASC 810-10-15-14. The Company’s determination of the primary beneficiary of a VIE considers all relationships between the Company and the VIE, including management agreements, governance documents and other contractual arrangements. The Company has determined for its VIEs that the Company is the primary beneficiary because it has both of the following characteristics: (a) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance, and (b) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Accordingly, the Company includes the assets and liabilities and results of operations of these entities in its condensed consolidated financial statements, even though the Company may not hold a majority equity interest. There have been no changes during 2018 in the accounting treatment or characterization of any previously identified VIE. The Company continues to reassess these relationships quarterly. The assets of these joint ventures are restricted in that they are not available for general business use outside the context of such joint ventures. The holders of the liabilities of each joint venture have no recourse to the Company. The Company does not have a variable interest in any unconsolidated VIEs.
