With the Nike x MMW Free TR 3 SP, Alyx founder and creative director Matthew M. Williams extends the investigations in balancing technical processes with traditional craft that have characterized his collaborative efforts to date. The shoe follows themes introduced in the MMW Series 2 collection, creating conversation between interior and exterior spaces and finding opportunity for transformative elements that shape-shift depending on environment. Specifically, Nike and Williams worked with outsole specialists Vibram to create a detachable crampon, extending the use of the traditional trainer. "This shoe embodies the multi-functionality of our modern urban existence," says Williams. "We are proud to have collaborated with Vibram on the detachable crampon rubber sole, which allows for the shoe to be used as a minimal trainer inside of a gym or as a resilient boot on city streets or park trails."
