This is Trash. The Space Hippie is all about the concept “Trash Transformed”. From upper to outsole, the Space Hippie 04 is made of at least 25% recycled materials. The shoe is not only the lightest weight shoe in the Space Hippie collection, but also the model with the smallest carbon footprint. The “Space Waste” yarn in the upper is 85% recycled polyester made from plastic bottles, T-shirts and yarn waste. The soft Crater Foam midsole combines Nike Grind Rubber with a combination of a wide variety of foams for stability and a unique look.
