Bar setting efficiency! Unlike traditional shoe construction, the Nike Crater Impact's thoughtful and modern design takes pattern efficiency and waste reduction seriously. Its straight-edged overlays mean no extra scraps. Its Crater foam midsole is made from waste found on the cutting-room floor and adds stability with a unique aesthetic. From eye-catching webbing accents made from recycled fabric to deco-stitching, no detail is overlooked so you can do good by looking good.
