The Nike women’s Waffle Racer Crater ‘White Black’ highlights neutral tones on a modern, sustainable interpretation of the 1977 original. White recycled twill makes up the composition of the upper, reinforced with grey suede overlays at the toe and heel. Zigzag stitching surrounds a black leather Swoosh, while recycled polyester is used on the eyestay webbing, tongue and vamp. The sneaker rides on a Crater Foam midsole made with 10% Nike Grind rubber and standard foam materials. Underfoot, the speckled waffle outsole is built with 15% Nike Grind rubber.
