Blazing a trail on the New York retail scene back in the late 80′s, Union NYC would be the first outlet for many different brands over the course of its illustrious history. As a well-respected cornerstone of streetwear retail, the store links up with Nike Sportswear on a Dunk High Challenge Supreme. Borrowing the iconic aesthetics of the Agassi signature Tech Challenge II, we see bits of this applied to the Dunk High. A logo strap is also added to the product with Union NYC icons on the heel as well. Only 100 pairs are rumored to be in existence and available now via Osneaker.com.
