These black Rick Owens x Birkenstock Arizona leather sandals feature an open round toe, two extended adjustable buckle-fastening straps, a leather insole and rubber sole. What's better than a pair of classique Birks? A pair designed by Mr. Owens, ofc. In the words of the American designer: 'it’s funny—you just assume that they have [collaborated], because everyone has done their ‘version of,’ but there’s never been an official Birkenstock-endorsed one. That’s why I wanted to do it'. Well Rick, we're so glad you were the first. We're wearing ours to the beach.
