For AW'15 Raf Simmons has continued his unique approach to the art of collaboration, bringing back some of Adidas long lost performance footwear and reinventing it in his own inimitable style. The Adidas x Raf Simons Response Trail is constructed with suede and mesh uppers play host to a adjustable heel strap alongside a variety of multicoloured silicone bubbles that play with this classic running silhouette. A directional reworking of an adidas classic, this new design plays host to a variety of performance technology, with a Formotion sole unit, Adiprene midsole and rugger Traxion outsole.
