The Nike Space Hippie 02 ‘This Is Trash’ is drawn from a sustainable collection that uses Space Waste Yarn on the upper of each shoe. The material is built with roughly 90% recycled polyester, itself made with recycled plastic bottles, T-shirts and yarn scraps. The slip-on silhouette rides on a Crater Foam midsole, comprising a blend of standard Nike foams with Nike Grind Rubber. A sockliner made with recycled ZoomX foam delivers lightweight cushioning.
