by Stella McCartney UltraBoost x Parley Running Shoe (Women)

Designed in an earth-friendly collaboration with Stella McCartney and marine custodian Parley for the Oceans, this lightweight running shoe provides cushioning and stability engineered exclusively for a woman's foot. The sock-like adidas Primeknit upper maintains a flexible, breathable fit with a responsible twist: It's knit with yarn made of reclaimed and recycled ocean plastic. To keep you comfortably ahead of the pack, the adaptive arch lifts free from the sole to provide snug support atop a bed of boost™ responsive cushioning. The layered sole is molded with grippy, perforated Continental™ Rubber over ultra-flexible STRETCHWEB rubber for a supercharged ride that delivers reliable traction on dry ground or even in ocean spray.
