NBA player Bob Lanier had big feet. Imelda Marcos has a big shoe collection. Founder of Blippy, AdBrite, and F*cked Company, Phil Kaplan, a.k.a. "Pud," has big feet and a collection of 40 Adidas sneakers all at the same time.
With that kind of collection, Phil Kaplan is undoubtedly an Adidas Advocate. He participates on the Adidas boards explicitly, and wears them all the time so you know he loves these sneaks.
