Mr Yohji Yamamoto refers to adidas' expansive archives to find inspiration for Y-3's designs. These 'FYW S-97' sneakers are an update to 1997's landmark 'Salvation' sneakers, which were the first running style to have 'Feet You Wear' responsive technology. They're made with sock-like Primeknit uppers, have flexible yet supportive cages around the forefeet and are set on layered foam and rubber boost™ soles.
