Year It First Dropped: 2003

In 2003, adidas asked legendary Japanese designer Yohji Yamamoto to create a pair of sneakers. Limited to 50,000 pairs worldwide, they sold out in no time. That led to the creation of Y-3, a whole new brand where Yamamoto was the creative director. The Y stood for the designer of course, and the 3 represented adidas' three-stripe logo. The aim of this project was to blur the line between athletic wear and fashion, and the debut collection all contained some variation of adidas' trademark stripes. Of course, it was so successful that Y-3 is about to celebrate its 10th anniversary.
