Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Wolverine World Wide, Inc. (the “Company”) is a leading designer, manufacturer, marketer and licensor of a broad range of quality casual footwear and apparel; performance outdoor and athletic footwear and apparel; children’s footwear; industrial work shoes, boots and apparel; and uniform shoes and boots. The Company’s portfolio of owned and licensed brands includes: Bates^®, Cat^®, Chaco^®, Harley-Davidson^®, Hush Puppies^®, HyTest^®, Keds^®, Merrell^®, Saucony^®, Sebago^®, Sperry^®, Stride Rite^® and Wolverine^®. Licensing and distribution arrangements with third parties extend the global reach of the Company’s brand portfolio. The Company also operates a consumer-direct division to market both its own brands and branded footwear and apparel from other manufacturers, as well as a leathers division that markets Wolverine Performance Leathers™. 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 fiscal 2016 Form 10-K. 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 2017 and 2016 both have 52 weeks. Prior to fiscal 2017, the Company reported its quarterly results of operations on the basis of 12-week periods for each of the first three fiscal quarters and a 16 or 17-week period for the fiscal fourth quarter. Beginning in fiscal 2017, the Company's fiscal year will be comprised of 13-week quarters for each of the first three fiscal quarters and a 13 or 14-week period for the fiscal fourth quarter. There is no change to the Company’s annual fiscal year reporting. References to the “quarter ended” or “third quarter” refer to the 13-week period ended September 30, 2017 or the 12-week period ended September 10, 2016. References to the “first three quarters” refer to the 39-week period ended September 30, 2017 or the 36-week period ended September 10, 2016. Revenue Recognition Revenue is recognized on the sale of products manufactured or sourced by the Company when the related goods have been shipped, legal title has passed to the customer and collectability is reasonably assured. Revenue generated through licensees and distributors involving products bearing the Company’s trademarks is recognized as earned according to stated contractual terms upon either the purchase or shipment of branded products by licensees and distributors. Retail store revenue is recognized at time of sale. The Company records provisions for estimated sales returns and allowances at the time of sale based on historical rates of returns and allowances and specific identification of outstanding returns not yet received from customers. However, estimates of actual returns and allowances in any future period are inherently uncertain and actual returns and allowances may differ from these estimates. If actual or expected future returns and allowances were significantly greater or less than established reserves, a reduction or increase to net revenue would be recorded in the period this determination was made. Cost of Goods Sold Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs. Warehousing costs are included in selling, general and administrative expenses. Seasonality The Company’s business is subject to seasonal influences that can cause significant differences in revenue, earnings and cash flows from quarter to quarter; however, the differences have followed a consistent pattern in recent years. Prior to fiscal 2017, the Company’s fiscal year had 12 weeks in each of the first three fiscal quarters and, 16 weeks in the fourth fiscal quarter, which also impacted the comparability from quarter to quarter.

New Accounting Standards

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) that have been adopted by the Company during fiscal 2017. The following is a summary of the effect of adoption of these new standards.



Standard	Description	Effect on the Financial Statements or Other Significant Matters
ASU 2015-11, Simplifying the Measurement of Inventory	Requires that an entity measure inventory at the lower of cost and net realizable value. This ASU does not apply to inventory measured using last-in, first-out.	The adoption of the new standard in fiscal 2017 did not have, nor does the Company believe it will have, a material impact on the accounting for its inventory.
ASU 2016-05, Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships	Clarifies that the novation of a derivative contract (i.e., a change in the counterparty) in a hedge accounting relationship does not, in and of itself, require dedesignation of that hedge accounting relationship, provided that all other hedge accounting criteria continue to be met.	The adoption of the new standard in fiscal 2017 did not have, nor does the Company believe it will have, a material impact on the accounting for its derivatives.
ASU 2016-09, Improvements to Employee Share-Based Payment Accounting	Seeks to provide simplification to issues of share-based payment awards in relation to income tax consequences, forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows.	The adoption of the new standard in fiscal 2017 did not have a significant impact on the Company’s results of operations and cash flows.
ASU 2017-01, Clarifying the Definition of a Business	Clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.	The adoption of the new standard in fiscal 2017 did not have a significant impact on the Company’s results of operations and cash flows.

The FASB has issued the following ASUs that have not yet been adopted by the Company. The following is a summary of the planned adoption period and anticipated impact of adopting these new standards.



Standard	Description	Planned Period of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities	Enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This ASU addresses certain aspects of recognition, measurement, presentation and disclosure of financial statements.	Q1 2018	The Company is evaluating the impacts of the new standard on its consolidated financial statements.
ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	Sponsors of benefit plans would be required to present service cost in the same line item or items as other current employee compensation costs, and present the remaining components of net benefit cost in one or more separate line items outside of income from operations, while also limiting the components of net benefit cost eligible to be capitalized to service cost.	Q1 2018	The Company does not expect the adoption of the new standard to have a significant impact on its consolidated financial position, results of operations or cash flows. The new standard will require the Company to present the non-service pension costs as a component of expense below operating profit.
ASU 2016-02, Leases	The core principle is that a lessee shall recognize a lease asset and lease liability in its statement of financial position. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term.	Q1 2019	The Company is evaluating the impacts of the new standard on its existing leases.
ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities	Seeks to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities and to reduce the complexity of and simplify the application of hedge accounting. This ASU eliminates the requirement to separately measure and report hedge ineffectiveness.	Q1 2019	The Company is evaluating the impacts of the new standard on its existing derivative contracts.
ASU 2016-13, Measurement of Credit Losses on Financial Instruments	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 [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.



(In millions, except per share data)	13 Weeks Ended September 30, 2017			12 Weeks Ended September 10, 2016			39 Weeks Ended September 30, 2017			36 Weeks Ended September 10, 2016

For the 13 and 39 weeks ended September 30, 2017, options relating to 1,006,123 and 1,804,594 shares of common stock outstanding, respectively, have not been included in the denominator for the computation of diluted earnings per share because they were anti-dilutive.

For the 12 and 36 weeks ended September 10, 2016, options relating to 1,968,599 and 4,636,609 shares of common stock outstanding, respectively, have not been included in the denominator for the computation of diluted earnings per share because they were anti-dilutive.

Goodwill and Indefinite-Lived Intangibles

GOODWILL AND INDEFINITE-LIVED INTANGIBLES

The changes in the carrying amount of goodwill and indefinite-lived intangibles are as follows:



(In millions)	Goodwill		Indefinite-lived intangibles			Total
Balance at January 2, 2016	$	429.1	$	685.4		$	1,114.5
Purchase of intangibles	—		0.2			0.2

Sale of intangibles	—		(5.4		)	(5.4		)
Foreign currency translation effects	5.6		—			5.6
Balance at September 30, 2017	$	429.9	$	673.1		$	1,103.0

In the fourth quarter of fiscal 2016, the results of our indefinite-lived intangible impairment test based on the Company's outlook for future operating results continued to support the book value of the Sperry^® trade name. If the operating results for Sperry^® were to decline in future periods, the Company may record a non-cash indefinite-lived intangible asset impairment charge. The carrying value of the Company’s Sperry^® trade name indefinite-lived intangible assets was $586.8 million, as of September 30, 2017.

In the third quarter of fiscal 2017, the Company sold certain intangible assets related to its Sebago^® brand. See Note 16 for additional information.

ACCOUNTS RECEIVABLE

The Company has an agreement with a financial institution to sell selected trade accounts receivable on a recurring, nonrecourse basis. The agreement, which expires in the fourth quarter of fiscal 2017, will renew for a one year term if not otherwise terminated or amended. Under the agreement, up to $200.0 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 for all periods presented. For receivables sold under the agreement, 90% of the stated amount is paid for in cash to the Company at the time of sale, with the remainder paid to the Company at the completion of the collection process. The following is a summary of the stated amount of accounts receivable that was sold as well as fees charged by the financial institution.

Total debt	$	796.7		$	820.7		$	1,052.4

On September 15, 2016, the Company amended its credit agreement (as amended, the "Credit Agreement"). The Credit Agreement provided a $588.8 million term loan facility (“Term Loan A”) and a $600.0 million revolving credit facility (the “Revolving Credit Facility”), both with maturity dates of July 13, 2020. 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 July 13, 2020. The scheduled principal payments due over the next 12 months total $48.8 million as of September 30, 2017 and are recorded as current maturities of long-term debt on the consolidated condensed balance sheet.

The Revolving Credit Facility allows the Company to borrow up to an aggregate amount of $600.0 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 $2.5 million, $2.6 million and $2.6 million as of September 30, 2017, December 31, 2016 and September 10, 2016, 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 0.25% to 1.00%, or (2) the Eurocurrency Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 1.25% to 2.00% (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 30, 2017, Term Loan A had a weighted-average interest rate of 2.97%.

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; a maximum Consolidated Secured 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 30, 2017, 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 $3.6 million, $1.8 million and $1.2 million as of September 30, 2017, December 31, 2016 and September 10, 2016, respectively.

The Company has a capital lease obligation with payments scheduled to continue through February 2022.

The Company included in interest expense the amortization of deferred financing costs of $0.7 million and $2.1 million for the 13 and 39 weeks ended September 30, 2017, respectively. The Company included in interest expense the amortization of deferred financing costs of $0.8 million and $2.2 million for the 12 and 36 weeks ended September 10, 2016, respectively.

Financial Instruments and Risk Management

Financial Instruments and Risk Management

DERIVATIVE FINANCIAL INSTRUMENTS

The Company follows FASB ASC Topic 815, Derivatives and Hedging ("ASC 815"), which is intended to improve transparency in financial reporting and 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 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 extend out to a maximum of 363 days, 356 days and 335 days, as of September 30, 2017, December 31, 2016 and September 10, 2016, respectively. The Company also utilizes foreign currency forward exchange contracts that are not designated as hedging instruments to manage foreign currency translation 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, one of which matured on October 6, 2017, and the other, unless otherwise terminated, will mature on July 13, 2020. 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 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 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 USD 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 accumulated other comprehensive income (loss), offsetting the currency translation adjustment related to the underlying net investment that is also recorded in accumulated other comprehensive income (loss). All other changes in fair value are recorded in interest expense.

The notional amounts of the Company’s derivative instruments are as follows:



(Dollars in millions)	September 30, 2017		December 31, 2016		September 10, 2016
Foreign exchange contracts:
Hedge contracts	$	159.8	$	169.2	$	161.4
Non-hedge contracts	—		2.1		10.8
Interest rate swaps	464.0		496.0		537.9
Cross currency swap	106.4		—		—

The recorded fair values of the Company’s derivative instruments are as follows:

Interest rate swaps	(3.0		)	(5.3		)	(12.1		)
Cross currency swap	(11.8		)	—			—

Hedge effectiveness on the foreign exchange contracts is evaluated by the hypothetical derivative method. Any hedge ineffectiveness is reported within the cost of goods sold line item in the consolidated condensed statements of operations. Hedge ineffectiveness was not material to the Company’s consolidated condensed financial statements for the quarters ended September 30, 2017 and September 10, 2016. If, in the future, the foreign exchange contracts are determined to be ineffective hedges or terminated before their contractual termination dates, the Company would be required to reclassify into earnings all or a portion of the unrealized amounts related to the cash flow hedges that are currently included in Accumulated other comprehensive income (loss) (“AOCI”) within stockholders’ equity.

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 borrowings, as well as its risk management objective and strategy for undertaking the hedge transaction. This process included linking the derivative to the specific liability or asset on the balance sheet. The Company also assessed at the hedges’ inception, and continues to assess on an ongoing basis, whether the derivatives used in the hedging transaction are highly effective in offsetting changes in the cash flows of the hedged item. The effective portion of unrealized gains (losses) is deferred as a component of AOCI and will be recognized in earnings at the time the hedged item affects earnings. Any ineffective portion of the change in fair value will be immediately recognized as a component of interest expense.

Hedge effectiveness on the cross currency swap is assessed using the spot method. 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 hedges’ 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 effective portion of unrealized gains (losses) is deferred as a component of AOCI and will be recognized in earnings at the time the hedged item affects earnings. Any ineffective portion of the change in fair value will be immediately recognized as a component of interest expense.

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 generally lower 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 has not provided for U.S. taxes for earnings generated in foreign jurisdictions because it intends to reinvest these earnings indefinitely outside the U.S. However, if certain foreign earnings previously treated as permanently reinvested are repatriated, the additional U.S. tax liability could have a material adverse effect on the Company’s results of operations and financial position. The Company’s effective tax rates for the 13 and 39 weeks ended September 30, 2017 were 15.9% and 14.6%, respectively. The Company’s effective tax rates for the 12 and 36 weeks ended September 10, 2016 were 19.5% and 24.1%, respectively. The lower effective tax rate in the current year periods reflects a reduction in U.S. income due to higher restructuring and impairment costs and organizational transformation costs. The Company is subject to periodic audits by domestic and foreign tax authorities. Currently, the Company is undergoing routine periodic audits in both domestic and foreign 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 2012 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 30, 2017			December 31, 2016			September 10, 2016
Financial assets:
Derivatives	$	0.2		$	6.7		$	2.5
Financial liabilities:
Derivatives	$	(20.4	)	$	(5.6	)	$	(14.2	)

The fair value of foreign currency forward exchange contracts represents the estimated receipts or payments necessary to terminate the contracts. The 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.

Nonrecurring Fair Value Measurements

The following is a summary of assets and impairments that were measured at fair value on a nonrecurring basis.



	39 Weeks Ended September 30, 2017
(In millions)	Fair Value		Impairment
Property and equipment	$	—	$	9.6

The property and equipment was valued using an income approach based on the discounted cash flows expected to be generated by the underlying assets (Level 3).

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 carrying value and the fair value of the Company’s debt, excluding capital leases, are as follows:



(In millions)	September 30, 2017		December 31, 2016		September 10, 2016
Carrying value	$	796.2	$	820.2	$	1,051.8
Fair value	815.2		827.6		1,092.1

The fair value of the fixed rate debt was based on third-party quotes (Level 2). The fair value of the variable rate debt was calculated by discounting the future cash flows to its present value using a discount rate based on the risk-free rate of the same maturity (Level 3).

Litigation and Contingencies

LITIGATION AND CONTINGENCIES

The Company is involved in various environmental claims and other legal actions. The environmental claims include sites where the U.S. Environmental Protection Agency, state or local regulators have notified the Company that it is a potentially responsible party with respect to environmental remediation activities. These claims are subject to ongoing environmental impact studies, assessment, remediation, allocation of costs between responsible parties, where applicable, and concurrence by regulatory authorities and have not yet advanced to a stage where the Company’s liability is fixed. However, after taking into consideration legal counsel’s evaluation of all actions and claims against the Company, it is management’s opinion that the outcome of these matters are not expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

The Company is also involved in routine 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.

The Company used Scotchgard™, a product that included compounds commonly referred to as PFAS, in the Company’s former tannery operations. PFAS have recently been detected in ground water samples taken at the former tannery site and near sites where the Company disposed of tannery byproducts. This may result in claims against the Company or other liabilities. The Company is working with state and local regulators to investigate and monitor the situation.

Minimum future royalty and advertising obligations for the fiscal periods subsequent to September 30, 2017 under the terms of certain licenses held by the Company are as follows:



(In millions)	2017		2018		2019		2020		2021		Thereafter

Minimum advertising	0.7		2.9		3.0		3.1		3.2		10.2

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 $0.7 million and $1.8 million for the 13 and 39 weeks ended September 30, 2017, respectively. For the 12 and 36 weeks ended September 10, 2016, the Company incurred royalty expense, in accordance with these agreements, of $0.5 million and $1.4 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 $2.5 million for the 13 and 39 weeks ended September 30, 2017, respectively. For the 12 and 36 weeks ended September 10, 2016, the Company incurred advertising expense, in accordance with these agreements, of $0.7 million and $2.3 million, respectively.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2017
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Wolverine World Wide, Inc. (the “Company”) is a leading designer, manufacturer, marketer and licensor of a broad range of quality casual footwear and apparel; performance outdoor and athletic footwear and apparel; children’s footwear; industrial work shoes, boots and apparel; and uniform shoes and boots. The Company’s portfolio of owned and licensed brands includes: Bates^®, Cat^®, Chaco^®, Harley-Davidson^®, Hush Puppies^®, HyTest^®, Keds^®, Merrell^®, Saucony^®, Sebago^®, Sperry^®, Stride Rite^® and Wolverine^®. Licensing and distribution arrangements with third parties extend the global reach of the Company’s brand portfolio. The Company also operates a consumer-direct division to market both its own brands and branded footwear and apparel from other manufacturers, as well as a leathers division that markets Wolverine Performance Leathers™.
Basis of Presentation	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 fiscal 2016 Form 10-K.
Fiscal Period, Policy [Policy Text Block]	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 2017 and 2016 both have 52 weeks. Prior to fiscal 2017, the Company reported its quarterly results of operations on the basis of 12-week periods for each of the first three fiscal quarters and a 16 or 17-week period for the fiscal fourth quarter. Beginning in fiscal 2017, the Company's fiscal year will be comprised of 13-week quarters for each of the first three fiscal quarters and a 13 or 14-week period for the fiscal fourth quarter. There is no change to the Company’s annual fiscal year reporting. References to the “quarter ended” or “third quarter” refer to the 13-week period ended September 30, 2017 or the 12-week period ended September 10, 2016. References to the “first three quarters” refer to the 39-week period ended September 30, 2017 or the 36-week period ended September 10, 2016.
Revenue Recognition	Revenue Recognition Revenue is recognized on the sale of products manufactured or sourced by the Company when the related goods have been shipped, legal title has passed to the customer and collectability is reasonably assured. Revenue generated through licensees and distributors involving products bearing the Company’s trademarks is recognized as earned according to stated contractual terms upon either the purchase or shipment of branded products by licensees and distributors. Retail store revenue is recognized at time of sale. The Company records provisions for estimated sales returns and allowances at the time of sale based on historical rates of returns and allowances and specific identification of outstanding returns not yet received from customers. However, estimates of actual returns and allowances in any future period are inherently uncertain and actual returns and allowances may differ from these estimates. If actual or expected future returns and allowances were significantly greater or less than established reserves, a reduction or increase to net revenue would be recorded in the period this determination was made.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs. Warehousing costs are included in selling, general and administrative expenses.
Seasonality	Seasonality The Company’s business is subject to seasonal influences that can cause significant differences in revenue, earnings and cash flows from quarter to quarter; however, the differences have followed a consistent pattern in recent years. Prior to fiscal 2017, the Company’s fiscal year had 12 weeks in each of the first three fiscal quarters and, 16 weeks in the fourth fiscal quarter, which also impacted the comparability from quarter to quarter.

Earnings Per Share (Policies)	9 Months Ended
Earnings Per Share (Policies)	Sep. 30, 2017
Earnings Per Share [Abstract]
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.

Description

Planned Period of Adoption

Effect on the Financial Statements or Other Significant Matters

ASU 2014-09, Revenue from Contracts with Customers (as amended by ASUs 2015-04, 2016-08, 2016-10, 2016-12 and 2017-10)

The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also amends the required disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

The Company does not expect the adoption of the new standard to have a significant impact on its consolidated financial position, results of operations or cash flows. The effect on results is not expected to be material because the Company’s analysis of contracts under the new revenue recognition standard supports the recognition of revenue at a point in time for the majority of contracts, which is consistent with the current revenue recognition model. Revenue on the majority of contracts will continue to be recognized at a point in time because of the distinct transfer of control to the customer. The Company will adopt the standard using the modified retrospective method.
