Space Hippie 01 is made from at least 50% recycled material by weight. Its "Space Waste Yarn" upper includes about 90% recycled polyester made from recycled plastic bottles, t-shirts and yarn scraps. A soft, Crater Foam midsole combines Nike Grind with a blend of foams for stability and a unique aesthetic, while the shoe's insole is made from ZoomX foam scraps, the same cushioning that creates the running shoes.
