Today is a big day for sneaker heads: not only is Riccardo Tisci’s Nike Air Force 1 collaboration officially on sale, we're also lucky enough to get a closer look at the latest collaboration between Raf Simons, the head of Christian Dior, and Adidas. Simons first teamed up with Adidas last year, remixing two shoes from the '90s, the Response and Oweego. He's taking on the Stan Smith tennis shoe and Bounce trainer, reimagining them with patterns from his own apparel in comic book and lego-inspired colors. Priced at $440-570, the 20-piece collection will drop in the coming weeks at Adidas Originals store and boutiques and retailers carrying Raf like oki-ni. Check out some of the styles below.
