Re: Wolverine World Wide, Inc. – Registration Statement on Form S-4

Ladies and Gentlemen:

We have examined the Registration Statement on Form S-4 (the “Registration Statement”) of Wolverine World Wide, Inc., a Delaware corporation (the “Company”), and certain direct and indirect wholly-owned subsidiaries of the Company listed as co-registrants thereto (collectively, the “Guarantors”), filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), in connection with the offering by the Company of up to $375,000,000 aggregate principal amount of its 6.125% Senior Notes due 2020 (the “Exchange Notes”) and the guarantees of the Company’s obligations under the Exchange Notes (the “Guarantees”), in exchange for a like principal amount of its outstanding 6.125% Senior Notes due 2020 (the “Outstanding Notes”).

We have examined the originals, or copies certified or otherwise identified to our satisfaction, of the Indenture, dated as of October 9, 2012 (the “Indenture”), among the Company, the Guarantors and Wells Fargo Bank National Association, as Trustee (the “Trustee”), and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed relevant and necessary as the basis for the opinions set forth below. The Exchange Notes, the Guarantees and the Indenture are each governed by the laws of the State of New York and are sometimes collectively referred to herein as the “Documents.” In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies.

We are not admitted to practice law in the States of Massachusetts or Michigan. Therefore, with the Company’s consent and at its request, we have relied upon the legal opinions of Barnes & Thornburg LLP and Seyfarth Shaw LLP of even date herewith, filed as exhibits to the Registration Statement, with respect to matters governed by the laws of Massachusetts and Michigan, respectively, that are material to our legal opinion and are assuming the accuracy of such opinions without independent verification.

1. With respect to the Exchange Notes, when the Exchange Notes are executed and authenticated in accordance with the provisions of the Indenture and issued and delivered in exchange for the Outstanding Notes in the manner described in the Registration Statement, the Exchange Notes will constitute valid and binding obligations of the Company.

2.
