Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for a complete presentation of the financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included in the accompanying financial statements. For further information, refer to the consolidated financial statements and footnotes included in the Company’s 2018 Form 10-K. As described in Note 2, the Company adopted ASU 2016-02, Leases , at the beginning of the first quarter of fiscal 2019.

As described in Note 16, the Company realigned certain brands into a new operating segment during the first quarter of fiscal 2019. All prior period disclosures have been restated to reflect the new reportable operating segments. Fiscal Year The Company’s fiscal year is the 52 or 53-week period that ends on the Saturday nearest to December 31. Fiscal years 2019 and 2018 both have 52 weeks. The Company reports its quarterly results of operations on the basis of 13-week quarters for each of the first three fiscal quarters and a 13 or 14-week period for the fiscal fourth quarter.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	NEW ACCOUNTING STANDARDS The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) that the Company has adopted during fiscal 2019 . The following is a summary of the effect of adoption of this new standard. Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2016-02, Leases (as amended by ASUs 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01) The core principle is that a lessee shall recognize a lease liability in its statement of financial position for the present value of all future lease payments. A lessee would also recognize a right-of-use asset representing its right to use the underlying asset for the lease term. Under a new transition method, a reporting entity will apply the new lease requirements as of the effective date and continue to report comparative periods presented in the financial statements under GAAP in effect during the comparable periods. The Company adopted ASU 2016-02 at the beginning of the first quarter using the modified retrospective approach and elected the package of practical expedients for its existing leases. The Company recognized a lease liability of $178.1 million, which was equal to the present value of the future lease payments for its portfolio of operating leases. The Company recognized a right-of-use asset of $157.3 million, which was equal to the lease liabilities adjusted for the balance of accrued rent and unamortized lease incentives as of the effective date. The adoption of ASU 2016-02 did not have a material impact on the Company’s results of operations or cash flows. See Note 8 for additional information on the adoption of this standard and disclosures regarding the Company’s leases. The FASB has issued the following ASU that has not yet been adopted by the Company. The following is a summary of the planned adoption period and anticipated impact of adopting this new standard. Standard Description Planned Period of Adoption Effect on the Financial Statements or Other Significant Matters ASU 2016-13, Measurement of Credit Losses on Financial Instruments (as amended by ASU 2018-19) Seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates. Q1 2020 The Company is evaluating the impacts of the new standard on its existing financial instruments, including trade receivables.

Earnings Per Share

Earnings Per Share	9 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE The Company calculates earnings per share in accordance with FASB Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share (“ASC 260”). ASC 260 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting, and, therefore, need to be included in the earnings allocation in computing earnings per share under the two-class method. Under the guidance in ASC 260, the Company’s unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and must be included in the computation of earnings per share pursuant to the two-class method. The following table sets forth the computation of basic and diluted earnings per share. Quarter Ended Year-To-Date Ended (In millions, except per share data) September 28, September 29, September 28, September 29, Numerator: Net earnings attributable to Wolverine World Wide, Inc. $ 48.7 $ 58.8 $ 129.4 $ 160.8 Adjustment for earnings allocated to non-vested restricted common stock (1.0 ) (1.2 ) (2.6 ) (3.4 ) Net earnings used in calculating basic earnings per share 47.7 57.6 126.8 157.4 Adjustment for earnings reallocated from non-vested restricted common stock — — 0.1 0.1 Net earnings used in calculating diluted earnings per share $ 47.7 $ 57.6 $ 126.9 $ 157.5 Denominator: Weighted average shares outstanding 83.5 94.9 87.3 95.2 Adjustment for non-vested restricted common stock (0.5) (1.7) (0.7) (1.8) Shares used in calculating basic earnings per share 83.0 93.2 86.6 93.4 Effect of dilutive stock options 0.9 2.1 1.4 2.0 Shares used in calculating diluted earnings per share 83.9 95.3 88.0 95.4 Net earnings per share: Basic $ 0.57 $ 0.62 $ 1.46 $ 1.69 Diluted 0.57 0.60 1.44 1.65 For the quarter and year-to-date ended September 28, 2019 , 1,228,157 and 131,004 outstanding stock options, respectively, have not been included in the denominator for the computation of diluted earnings per share because they were anti-dilutive. For the quarter and year-to-date ended September 29, 2018 , 18,779 and 24,250 outstanding stock options, respectively, have not been included in the denominator for the computation of diluted earnings per share because they were anti-dilutive.

Accounts Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	ACCOUNTS RECEIVABLE The Company has an agreement with a financial institution to sell selected trade accounts receivable on a recurring, nonrecourse basis that expires in the fourth quarter of fiscal 2019. Under the agreement, up to $ 150.0 million of accounts receivable may be sold to the financial institution and remain outstanding at any point in time. After the sale, the Company does not retain any interests in the accounts receivable and removes them from its consolidated condensed balance sheet but continues to service and collect the outstanding accounts receivable on behalf of the financial institution. The Company recognizes a servicing asset or servicing liability, initially measured at fair value, each time it undertakes an obligation to service the accounts receivable under the agreement. The fair value of this obligation resulted in a nominal servicing liability as of the end of the third quarter of 2018. For receivables sold under the agreement, 90 % of the stated amount is paid in cash to the Company at the time of sale, with the remainder paid to the Company at the completion of the collection process. During the third quarter of fiscal 2018, the Company discontinued selling accounts receivables under the agreement. The Company continued to service the outstanding receivables until they were collected. The following is a summary of the stated amount of accounts receivable that was sold as well as fees charged by the financial institution. Quarter Ended Year-To-Date Ended (In millions) September 29, 2018 Accounts receivable sold $ 40.1 $ 264.3 Fees charged 0.2 1.3 The fees charged are recorded in other expense. Net proceeds of this program are classified in operating activities in the consolidated condensed statements of cash flows. This program reduced the Company's accounts receivable by $7.5 million as of September 29, 2018

Revenue from Contract with Customer [Text Block]	REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition and Performance Obligations The Company recognizes revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers . Revenue is recognized upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration to be received in exchange for those goods or services. The Company identifies the performance obligation in the contract, determines the transaction price, allocates the transaction price to the performance obligations and recognizes revenue upon completion of the performance obligation. Revenue is recognized net of variable consideration and any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company holds agreements to license symbolic intellectual property with minimum guarantees or fixed consideration. The Company has $ 35.2 million of remaining fixed transaction price under its license agreements as of September 28, 2019 , which it expects to recognize per the terms of its contracts over the course of time through December 2024 . The Company has elected to omit the remaining variable consideration under its license agreements given the Company recognizes revenue equal to what it has the right to invoice and that amount corresponds directly with the value to the customer of the Company’s performance to date. The Company provides disaggregated revenue by sales channel, including the wholesale and consumer-direct sales channels, reconciled to the Company’s reportable operating segments. The wholesale channel includes royalty revenues due to the similarity in the Company’s oversight and management, customer base, the performance obligation (footwear and apparel goods) and point in time completion of the performance obligation.

Components of variable consideration include trade discounts and allowances, product returns, customer markdowns, customer rebates and other sales incentives relating to the sale of the Company’s products. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales. These estimates take into consideration a range of possible outcomes, which are probability-weighted in accordance with the expected value method for relevant factors such as current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. Revenue recognized during the fiscal periods presented related to the Company’s contract liabilities was nominal. The Company’s contract balances are as follows: (In millions) September 28, December 29, September 29, Product returns reserve $ 9.5 $ 13.6 $ 13.7 Customer markdowns reserve 3.6 4.0 4.9 Other sales incentives reserve 1.9 2.3 2.5 Customer rebates liability 10.8 12.8 14.0 Customer advances liability 5.4 3.8 3.9 The amount of variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Actual amounts of consideration ultimately received may differ from initial estimates. If actual results in the future vary from initial estimates, the Company subsequently adjusts these estimates, which affects net revenue and earnings in the period such variances become known.

The Credit Agreement includes a $ 200.0 million term loan facility (“Term Loan A”) and an $ 800.0 million Revolving Credit Facility, both with maturity dates of December 6, 2023. The Credit Agreement’s debt capacity is limited to an aggregate debt amount (including outstanding term loan principal and revolver commitment amounts in addition to permitted incremental debt) not to exceed $ 1,750.0 million , unless certain specified conditions set forth in the Credit Agreement are met. Term Loan A requires quarterly principal payments with a balloon payment due on December 6, 2023. The scheduled principal payments due over the next 12 months total $ 10.0 million as of September 28, 2019 and are recorded as current maturities of long-term debt on the consolidated condensed balance sheets. The Revolving Credit Facility allows the Company to borrow up to an aggregate amount of $800.0 million , which includes a $ 200.0 million foreign currency subfacility under which borrowings may be made, subject to certain conditions, in Canadian dollars, British pounds, euros, Hong Kong dollars, Swedish kronor, Swiss francs and such additional currencies as are determined in accordance with the Credit Agreement. The Revolving Credit Facility also includes a $50.0 million swingline subfacility and a $50.0 million letter of credit subfacility. The Company had outstanding letters of credit under the Revolving Credit Facility of $ 3.9 million , $ 2.5 million and $ 2.5 million as of September 28, 2019 , December 29, 2018 and September 29, 2018 , respectively. These outstanding letters of credit reduce the borrowing capacity under the Revolving Credit Facility. The interest rates applicable to amounts outstanding under Term Loan A and to U.S. dollar denominated amounts outstanding under the Revolving Credit Facility will be, at the Company’s option, either (1) the Alternate Base Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 0.125% to 0.750% , or (2) the Eurocurrency Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 1.125% to 1.750% (all capitalized terms used in this sentence are as defined in the Credit Agreement). The Company has two interest rate swap arrangements that reduce the Company’s exposure to fluctuations in interest rates on its variable rate debt. At September 28, 2019 , Term Loan A and the Revolving Credit Facility had weighted-average interest rates of 3.24 % and 3.20% , respectively. The obligations of the Company pursuant to the Credit Agreement are guaranteed by substantially all of the Company’s material domestic subsidiaries and secured by substantially all of the personal and real property of the Company and its material domestic subsidiaries, subject to certain exceptions. The Credit Agreement also contains certain affirmative and negative covenants, including covenants that limit the ability of the Company and its Restricted Subsidiaries to, among other things: incur or guarantee indebtedness; incur liens; pay dividends or repurchase stock; enter into transactions with affiliates; consummate asset sales, acquisitions or mergers; prepay certain other indebtedness; or make investments, as well as covenants restricting the activities of certain foreign subsidiaries of the Company that hold intellectual property related assets. Further, the Credit Agreement requires compliance with the following financial covenants: a maximum Consolidated Leverage Ratio and a minimum Consolidated Interest Coverage Ratio (all capitalized terms used in this paragraph are as defined in the Credit Agreement). As of September 28, 2019 , the Company was in compliance with all covenants and performance ratios under the Credit Agreement. The Company has $ 250.0 million of senior notes outstanding that are due on September 1, 2026 (the “Senior Notes”). The Senior Notes bear interest at 5.00% with the related interest payments due semi-annually. The Senior Notes are guaranteed by substantially all of the Company’s domestic subsidiaries. The Company has a foreign revolving credit facility with aggregate available borrowings of $ 4.0 million that are uncommitted and, therefore, each borrowing against the facility is subject to approval by the lender. Borrowings against this facility were $ 0.3 million , $ 0.0 million and $ 1.5 million as of September 28, 2019 , December 29, 2018 and September 29, 2018 , respectively. Prior to fiscal 2019, the Company had a capital lease obligation. As a result of the adoption of ASU 2016-02, Leases, the capital lease is now classified as a financing lease and is no longer included in long term debt. The Company included in interest expense the amortization of deferred financing costs of $ 0.4 million and $ 1.2 million for the quarter and year-to-date ended September 28, 2019 , respectively. The Company included in interest expense the amortization of deferred financing costs of $ 0.6 million and $ 2.2 million for the quarter and year-to-date ended September 29, 2018 , respectively.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	LEASES The Company adopted ASU 2016-02, Leases , at the beginning of the first quarter of fiscal 2019 using the modified retrospective approach applied to all leases as of the date of application. The Company elected the package of practical expedients for leases existing as of the effective date under which it did not reassess whether contracts contain leases under the new definition of a lease, the lease classification or whether previously capitalized initial direct costs would qualify for capitalization under ASU 2016-02. In addition, the Company did not elect the hindsight practical expedient for considering judgments and estimates relating to its existing leases such as determining the remaining lease term. Description of Leases The Company’s leases consist primarily of corporate offices, retail stores, distribution centers, showrooms, vehicles and office equipment. The Company leases assets in the normal course of business to meet its current and future needs while providing flexibility to its operations. The Company enters into contracts with third parties to lease specifically identified assets. Most of the Company’s leases have contractually specified renewal periods. Most retail store leases have early termination clauses that the Company can elect if stipulated sales amounts are not achieved. The Company determines the lease term for each lease based on the terms of each contract and factors in renewal and early termination options if such options are reasonably certain to be exercised. Accounting for Leases Under FASB ASC Topic 842, Leases , the Company has elected the practical expedient to account for lease components and nonlease components associated with individual leases as a single lease component for all of its leases. In addition, the Company has elected to account for multiple lease components as a single lease component. The Company’s leases may include variable lease costs such as payments based on changes to an index, payments based on a percentage of retail store sales, and maintenance, utilities, shared marketing or other service costs that are paid directly to the lessor under terms of the lease. The Company recognizes variable lease payments when the amounts are incurred and determinable. The Company has elected to account for leases less than one year as short-term leases and accordingly does not recognize a right-of-use asset or lease liability for these leases. The Company recognizes rent expense on a straight-line basis over the lease term. The Company subleases certain portions of leased offices and distribution centers that exceed the Company’s current operational needs. Since the Company utilizes the majority of the leased space and retains the obligation to the lessor, the underlying leases continue to be accounted for as operating leases. Sublease income is recognized on a straight-line basis over the term of the sublease, and beginning in fiscal 2019, is recognized in Other income, net on the consolidated condensed statements of operations and comprehensive income. The Company recognizes a lease liability in current and noncurrent liabilities equal to the present value of the fixed future lease payments using an incremental borrowing rate as of the commencement date of each lease. The incremental borrowing rate is based on interest rate that the Company would normally pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments. The weighted-average discount rate for operating leases as of September 28, 2019 is 5.2 %. The Company also recognizes a right-of-use asset, which is equal to the lease liability as of September 28, 2019 adjusted for the remaining balance of accrued rent and unamortized lease incentives. The following is a summary of the Company’s lease cost. Quarter Ended Year-To-Date Ended (In millions) September 28, 2019 Operating lease cost $ 8.1 $ 24.3 Variable lease cost 3.6 10.9 Short-term lease cost 0.3 0.9 Sublease income (1.0 ) (2.9 ) Total lease cost $ 11.0 $ 33.2 The weighted-average remaining lease term for operating leases as of September 28, 2019 is 10.3 years. Future undiscounted cash flows for operating leases for the fiscal periods subsequent to September 28, 2019 are as follows: (In millions) Operating Leases Remainder of 2019 $ 8.7 2020 32.1 2021 29.3 2022 26.7 2023 19.9 Thereafter 122.3 Total future payments 239.0 Less: imputed interest 54.5 Recognized lease liability $ 184.5 The Company made cash payments of $ 24.4 million for operating lease liabilities during the year-to-date ended September 28, 2019 . During the year-to-date ended September 28, 2019 , the Company entered into new or amended leases that resulted in the noncash recognition of right-of-use assets and lease liabilities of $ 25.0 million . In addition, the Company entered into real estate leases which will commence subsequent to September 28, 2019 with future undiscounted rental payments of $ 4.8 million . The Company has a financing lease with future payments of $ 0.3 million and a remaining term of 2.3 years.

Financial Instruments and Risk Management	DERIVATIVE FINANCIAL INSTRUMENTS The Company follows FASB ASC Topic 815, Derivatives and Hedging ("ASC 815"), which requires that all derivative instruments be recorded on the consolidated condensed balance sheets at fair value by establishing criteria for designation and effectiveness of hedging relationships. The Company does not hold or issue financial instruments for trading purposes. The Company utilizes foreign currency forward exchange contracts designated as cash flow hedges to manage the volatility associated primarily with U.S. dollar inventory purchases made by non-U.S. wholesale operations in the normal course of business. These foreign currency forward exchange hedge contracts extended out to a maximum of 545 days, 524 days and 545 days, as of September 28, 2019 , December 29, 2018 and September 29, 2018 , respectively. If, in the future, the foreign exchange contracts are determined not to be highly effective or are terminated before their contractual termination dates, the Company would remove the hedge designation from those contracts and reclassify into earnings the unrealized gains or losses that would otherwise be included in accumulated other comprehensive income (loss) (“AOCI”) within stockholders’ equity. The Company also utilizes foreign currency forward exchange contracts that are not designated as hedging instruments to manage foreign currency transaction exposure. Foreign currency derivatives not designated as hedging instruments are offset by foreign exchange gains or losses resulting from the underlying exposures of foreign currency denominated assets and liabilities. The Company has two interest rate swap arrangements, which unless otherwise terminated, will mature on July 13, 2020 and December 6, 2023 , respectively. These agreements, which exchange floating rate for fixed rate interest payments over the life of the agreements without the exchange of the underlying notional amounts, have been designated as cash flow hedges of the underlying debt. The notional amounts of the interest rate swap arrangements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap arrangements is recognized as interest expense. In accordance with ASC 815, the Company has formally documented the relationship between the interest rate swaps and the variable rate borrowing, as well as its risk management objective and strategy for undertaking the hedge transactions. This process included linking the derivative to the specific liability or asset on the balance sheet. The Company also assessed at the inception of each hedge, and continues to assess on an ongoing basis, whether the derivatives used in the hedging transactions are highly effective in offsetting changes in the cash flows of the hedged item. The Company has a cross currency swap to minimize the impact of exchange rate fluctuations. The hedging instrument, which, unless otherwise terminated, will mature on September 1, 2021 , has been designated as a hedge of a net investment in a foreign operation. The Company will pay 2.75 % on the euro-denominated notional amount and receive 5.00 % on the U.S. dollar notional amount, with an exchange of principal at maturity. Changes in fair value related to movements in the foreign currency exchange spot rate are recorded in AOCI, offsetting the currency translation adjustment related to the underlying net investment that is also recorded in AOCI. All other changes in fair value are recorded in interest expense. In accordance with ASC 815, the Company has formally documented the relationship between the cross-currency swap and the Company’s investment in its euro-denominated subsidiary, as well as its risk management objective and strategy for undertaking the hedge transaction. This process included linking the derivative to its net investment on the balance sheet. The Company also assessed at the hedge’s inception, and continues to assess on an ongoing basis, whether the derivative used in the hedging transaction is highly effective in offsetting changes in expected cash flows of the hedged item. The notional amounts of the Company’s derivative instruments are as follows: (Dollars in millions) September 28, December 29, September 29, Foreign exchange contracts: Hedge contracts $ 237.7 $ 220.3 $ 215.5 Non-hedge contracts — 4.8 8.1 Interest rate swaps 366.2 181.3 376.1 Cross currency swap 79.8 95.8 95.8 The recorded fair values of the Company’s derivative instruments are as follows: (In millions) September 28, December 29, September 29, Financial assets: Foreign exchange contracts - hedge $ 6.3 $ 8.7 $ 3.9 Interest rate swaps — 1.6 3.6 Financial liabilities: Foreign exchange contracts - hedge $ (0.2 ) $ — $ (0.2 ) Interest rate swaps (3.0 ) — — Cross currency swap (2.1 ) (8.2 ) (12.1 )

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company maintains management and operational activities in overseas subsidiaries, and its foreign earnings are taxed at rates that are different than the U.S. federal statutory income tax rate. A significant amount of the Company’s earnings are generated by its Canadian, European and Asian subsidiaries and, to a lesser extent, in jurisdictions that are not subject to income tax. The Company intends to permanently reinvest all non-cash undistributed earnings outside of the U.S. and has, therefore not established a deferred tax liability on that amount of foreign unremitted earnings. However, if these non-cash undistributed earnings were repatriated, the Company would be required to accrue and pay applicable U.S. taxes and withholding taxes payable to various countries. It is not practicable to estimate the amount of the deferred tax liability associated with these non-cash unremitted earnings due to the complexity of the hypothetical calculation. The Company’s effective tax rates for the quarter and year-to-date ended September 28, 2019 were 20.3% and 17.9% , respectively. The Company’s effective tax rates for the quarter and year-to-date ended September 29, 2018 were 7.8% and 13.7% , respectively. The increase in the effective tax rate for the current year periods is due primarily to the favorable impact on the prior year tax rate for voluntary pension contributions made in 2018 . The Company is subject to periodic audits by U.S. federal, state, local and non-U.S. tax authorities. Currently, the Company is undergoing routine periodic audits in both U.S. federal, state, local and non-U.S. tax jurisdictions. It is reasonably possible that the amounts of unrecognized tax benefits could change in the next 12 months as a result of the audits; however, any payment of tax is not expected to be significant to the consolidated condensed financial statements. The Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2014 in the majority of tax jurisdictions.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	FAIR VALUE MEASUREMENTS The Company follows FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), which provides a consistent definition of fair value, focuses on exit price, prioritizes the use of market-based inputs over entity-specific inputs for measuring fair value and establishes a three-tier hierarchy for fair value measurements. ASC 820 requires fair value measurements to be classified and disclosed in one of the following three categories: Level 1: Fair value is measured using quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2: Fair value is measured using either direct or indirect inputs, other than quoted prices included within Level 1, which are observable for similar assets or liabilities. Level 3: Fair value is measured using valuation techniques in which one or more significant inputs are unobservable. Recurring Fair Value Measurements The following table sets forth financial assets and liabilities measured at fair value in the consolidated condensed balance sheets and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy. Fair Value Measurements Quoted Prices With Other Observable Inputs (Level 2) (In millions) September 28, December 29, September 29, Financial assets: Derivatives $ 6.3 $ 10.3 $ 7.5 Financial liabilities: Derivatives $ (5.3 ) $ (8.2 ) $ (12.3 ) The fair value of foreign currency forward exchange contracts represents the estimated receipts or payments necessary to terminate the contracts. The two interest rate swaps are valued based on the current forward rates of the future cash flows. The fair value of the cross-currency swap is determined using the current forward rates and changes in the spot rate. Fair Value Disclosures The Company’s financial instruments that are not recorded at fair value consist of cash and cash equivalents, accounts and notes receivable, accounts payable, borrowings under revolving credit agreements and other short-term and long-term debt. The carrying amount of these financial instruments is historical cost, which approximates fair value, except for the debt.

The Company also owns a parcel on House Street in Plainfield Township that the Company used for the disposal of Tannery byproducts until about 1970 (the "House Street" site). Beginning in the late 1950s, the Company used 3M Company’s Scotchgard™ in its processing of certain leathers at the Tannery. Until 2002 when 3M Company changed its Scotchgard™ formula, Tannery byproducts disposed of by the Company at the House Street site and other locations may have contained PFOA and/or PFOS, two chemicals in the family of compounds known as per- and polyfluoroalkyl substances (together, “PFAS”). PFOA and PFOS help provide non-stick, stain-resistant, and water-resistant qualities, and were used for many decades in commercial products like firefighting foams and metal plating, and in common consumer items like food wrappers, microwave popcorn bags, pizza boxes, Teflon™, carpets and Scotchgard™. The United States Centers for Disease Control and Prevention has concluded that studies of the health effects of PFOA and PFOS are “inconsistent and inconclusive,” but in May 2016, the Environmental Protection Agency (“EPA”) announced a lifetime health advisory level of 70 parts per trillion ("ppt") combined for PFOA and PFOS. Lifetime health advisories, while not enforceable, serve as guidance and are benchmarks for determining if concentrations of chemicals in tap water from public utilities are safe for public consumption. In January 2018, the Michigan Department of Environmental Quality (“MDEQ”) enacted a drinking water criterion of 70 ppt combined for PFOA and PFOS, which set an official state standard for acceptable concentrations of these contaminants in groundwater used for drinking water purposes. On April 22, 2019, the MDEQ was reorganized into the Michigan Department of Environment, Great Lakes, and Energy (“EGLE”). The Company has been served with two regulatory actions including a civil action filed by the EGLE under the federal Resource Conservation and Recovery Act of 1976 (“RCRA”), Part 201 of the Michigan Natural Resources and Environmental Protection Act (“NREPA”) and Part 31 of NREPA, and a Unilateral Administrative Order issued by the EPA under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) Section 106. The Company has also been served with individual lawsuits and three putative class action lawsuits. The three putative class action lawsuits were subsequently refiled as a single consolidated putative class action lawsuit. Civil and Regulatory Actions of EGLE and EPA On January 10, 2018, EGLE filed a civil action against the Company in the U.S District Court for the Western District of Michigan under RCRA and Parts 201 and 31 of NREPA alleging that the Company’s past and present handling, storage, treatment, transportation and/or disposal of solid waste at the Company’s properties has contributed to the disposal of solid wastes that was done in a way that resulted in releases of PFAS at levels that resulted in detections exceeding applicable Michigan cleanup criteria for PFOA and PFOS (the "EGLE Action"). Plainfield and Algoma Townships have intervened in the EGLE Action alleging claims under RCRA, CERCLA, Part 201 of NREPA, and common law nuisance. The EGLE Action seeks to require the Company to investigate the location and extent of PFAS in the environment, develop and implement plans for the continued sampling and analysis of impacts to drinking water wells from PFAS released or disposed of by the Company, and provide alternative drinking water supplies to homes impacted by PFAS for which the Company is allegedly responsible. The EGLE Action further seeks to require the Company to connect users of drinking water wells to municipal drinking water supplies to address allegedly unacceptable risks posed by a release or threat of release of PFAS attributable to the Company. On December 19, 2018, the Company filed a third-party complaint against the 3M Company seeking, among other things, recovery of the Company’s remediation and other costs incurred in defense of the EGLE Action. On June 20, 2019, the 3M Company filed a counterclaim against the Company in response to the Company’s third-party complaint in the EGLE Action, seeking, among other things, contractual and common law indemnity and contribution under CERCLA and Part 201 of NREPA. In July 2019, the Court ordered all parties to the EGLE Action (including the 3M Company as a third-party defendant) to participate in confidential mediation. Initial mediation sessions were held in September 2019, and the parties remain engaged in discussions. The Company is working with the EGLE to analyze the Tannery property, House Street site and other relevant disposal sites, test nearby residential drinking water wells and coordinate communications to impacted homeowners. The Company’s current remediation efforts have included, among other items, providing alternate drinking water to impacted homes, including bottled water and water filtration systems, sampling residential wells, installing and sampling monitoring wells, collecting and analyzing soil and sediment samples and designing and installing a groundwater extraction and treatment system at the Tannery property. The Company continues to collect and analyze this data on a continuing basis with the EGLE and EPA. On January 10, 2018, the EPA entered a Unilateral Administrative Order (the “Order”) under Section 106(a) of CERCLA, 42 U.S.C. § 9606(a). The effective date of the Order was February 1, 2018. The Order pertained to the Company's Tannery and House Street sites and directed the Company to conduct specified removal actions, including certain time critical removal actions subsequently identified in an April 29, 2019 letter from the EPA, to abate the actual or threatened release of hazardous substances at or from the sites. On October 28, 2019, the EPA and the Company entered into an Administrative Settlement and Order on Consent (“AOC”) that supersedes the Order and addresses the agreed-upon removal actions outlined in the Order. The Company has already completed some of these activities and submitted work plans for completion of the remaining items. The Company discusses its reserve for remediation costs in the environmental liabilities section below. Individual and Class Action Litigation Individual lawsuits and three putative class action lawsuits have been filed against the Company that raise a variety of claims, including claims related to property, remediation, and human health effects. The three putative class action lawsuits were subsequently refiled in the U.S. District Court for the Western District of Michigan as a single consolidated putative class action lawsuit. The 3M Company, which sold Scotchgard containing PFAS to the Company, has been named as a co-defendant in the individual lawsuits and consolidated putative class action lawsuit. In addition, the current owner of a former landfill and gravel mining operation has sued the Company seeking damages and cost recovery for property damage allegedly caused by the Company’s disposal of tannery waste containing PFAS (collectively with the individual lawsuits and putative class action, the “Litigation Matters”). Assessing potential liability with respect to the Litigation Matters at this time, however, is difficult. The Litigation Matters are in various stages of discovery and related motions. In addition, there is minimal direct and relevant precedent for these types of claims related to PFAS, and the science regarding the human health effects of PFAS exposure in the environment remains inconclusive and inconsistent, thereby creating additional uncertainties. Due to these factors, combined with the complexities and uncertainties of litigation, the Company is unable to conclude that adverse verdicts resulting from the Litigation Matters are probable, and therefore no amounts are currently reserved for these claims. The Company intends to continue to vigorously defend itself against these claims. In addition, in December 2018 the Company filed a lawsuit against certain of its historic liability insurers, seeking their participation in Wolverine's defense and remediation efforts. Other Litigation The Company is also involved in litigation incidental to its business and is a party to legal actions and claims, including, but not limited to, those related to employment and intellectual property. Some of the legal proceedings include claims for compensatory as well as punitive damages. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available and liabilities that have been recorded along with applicable insurance, it is management’s opinion that the outcome of these items are not expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. Environmental Liabilities The following is a summary of the activity with respect to an environmental remediation reserve established by the Company: Year-To-Date Ended (In millions) September 28, September 29, Remediation liability at beginning of the year $ 22.6 $ 31.1 Changes in estimate — 0.9 Amounts paid (7.8 ) (8.6 ) Remediation liability at the end of the quarter $ 14.8 $ 23.4 The reserve balance as of September 28, 2019 comprises $ 10.5 million that is expected to be paid within the next twelve months and is recorded as a current obligation in other accrued liabilities, with the remaining $ 4.3 million expected to be paid over the course of up to 27 years, recorded in other liabilities. The Company establishes a reserve for estimated environmental remediation costs based upon the evaluation of currently-available facts with respect to each individual site. The liabilities are recognized on an undiscounted basis when they are probable and reasonably estimable, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. Liabilities for estimated costs of environmental remediation are based primarily upon third-party environmental studies, other internal analysis and the extent of the contamination and the nature of required remedial actions at each site. No estimated recoveries from legacy insurance policies or other responsible parties are included in the reserve. The Company's remediation activity at the Tannery property, House Street site and other relevant disposal sites is ongoing. It is difficult to estimate the cost of environmental compliance and remediation given the uncertainties regarding the interpretation and enforcement of applicable environmental laws and regulations, the extent of environmental contamination and the existence of alternative cleanup methods. Developments may occur that could materially change the Company’s current cost estimates, including, but not limited to: (i) changes in the information available regarding the environmental impact of the Company’s operations and products; (ii) changes in environmental regulations, changes in permissible levels of specific compounds in drinking water sources, or changes in enforcement theories and policies, including efforts to recover natural resource damages; (iii) new and evolving analytical and remediation techniques; (iv) changes to the form of remediation; (v) success in allocating liability to other potentially responsible parties; and (vi) the financial viability of other potentially responsible parties and third-party indemnitors. For locations at which remediation activity is largely ongoing, the Company cannot estimate a possible loss or range of loss in excess of the associated established reserves for the reasons described above. The Company adjusts recorded liabilities as further information develops or circumstances change. Minimum Royalties and Advertising Commitments Minimum future royalty and advertising obligations for the fiscal periods subsequent to September 28, 2019 under the terms of certain licenses held by the Company are as follows: (In millions) 2019 2020 2021 2022 2023 Thereafter Minimum royalties $ — $ 1.5 $ 1.7 $ 1.8 $ — $ — Minimum advertising 0.3 3.2 3.3 3.4 3.5 3.6 Minimum royalties are based on both fixed obligations and assumptions regarding the Consumer Price Index. Royalty obligations in excess of minimum requirements are based upon future sales levels. In accordance with these agreements, the Company incurred royalty expense of $ 0.6 million and $ 1.6 million for the quarter and year-to-date ended September 28, 2019 , respectively. For the quarter and year-to-date ended September 29, 2018 , the Company incurred royalty expense in accordance with these agreements of $ 0.6 million and $ 1.7 million , respectively. The terms of certain license agreements also require the Company to make advertising expenditures based on the level of sales of the licensed products. In accordance with these agreements, the Company incurred advertising expense of $ 0.9 million and $ 2.8 million for the quarter and year-to-date ended September 28, 2019 , respectively. For the quarter and year-to-date ended September 29, 2018 , the Company incurred advertising expense in accordance with these agreements of $ 0.5 million and $ 2.2 million , respectively.

Business Combination Disclosure [Text Block]	BUSINESS ACQUISITIONS On April 30, 2019, the Company acquired assets and assumed liabilities from Sportlab S.R.L. (“Sportlab”), the distributor of Saucony ® footwear in Italy. Total purchase consideration of $ 25.1 million includes cash paid, extinguishment of Sportlab’s accounts payable balance that was due to the Company at the time of acquisition and contingent consideration. The contingent consideration is based on sales activity from the date of the acquisition through the remainder of fiscal 2019 and is valued based on the order backlog at the acquisition date. The maximum amount of contingent consideration for which the Company would be liable is $ 5.7 million and if earned, would be paid in the first quarter of fiscal 2020. The detailed amounts of each component of the purchase consideration are as follows: (In millions) Purchase Consideration Cash paid $ 15.1 Extinguishment of Sportlab’s accounts payable balance 4.6 Contingent consideration 5.4 Total purchase consideration $ 25.1 The Company accounted for the acquisition under the provisions of FASB ASC Topic 805, Business Combinations . The related assets acquired and liabilities assumed were recorded at fair value on the acquisition date. The operating results for the acquired Saucony ® distribution business are included in the Company’s consolidated condensed results of operations beginning April 30, 2019, and are included in the Wolverine Boston Group reporting group for segment reporting purposes. The preliminary allocation of the purchase price through September 28, 2019 was: (In millions) Initial Valuation Accounts receivable $ 1.8 Inventories 6.2 Goodwill 12.3 Amortizable intangibles 12.9 Total assets acquired 33.2 Deferred income taxes 3.6 Other liabilities 4.5 Total liabilities assumed 8.1 Net assets acquired $ 25.1 The allocation of the purchase price above is considered preliminary and was based upon valuation information available and estimates and assumptions made at September 28, 2019. The Company is still in the process of verifying data and finalizing information related to the valuation and recording of identifiable intangible assets, deferred taxes. uncertain tax positions, remaining contingent consideration and the resulting effects on the amount of recorded goodwill. The excess of the purchase price over the fair value of the net assets acquired, amounting to $12.3 million , was preliminarily recorded as goodwill in the condensed consolidated balance sheet and was assigned to the Wolverine Boston Group operating segment. The goodwill that was recognized is attributable to the efficiencies to be gained by integrating operations with the Saucony ® distribution business purchased from Sportlab. Other intangible assets acquired include order backlog, valued at $ 1.7 million , and customer relationship assets, valued at $ 11.2 million , which have estimated useful lives of 7 months and 14 years , respectively.
