Y-3 FYW S-97 Trainers in White / Black. Taking on a Three Stripes icon this season, Y-3 reimagine the ‘90s-hailing FYW S-97 sneaker with elevated appeal. Struck with Yohji Yamamoto’s signature on foot, this white pair feature multiple layers of Primeknit to the upper, with suede and leather overlays filtered throughout the design. To the toe, shell-like molds contour the foot, while springy Boost™ cushioning promises to provide a smooth ride through the city.
