Space Hippie is the story of trash transformed. By weight, the Space Hippie 04 is made from at least 25% recycled material, from the upper to the outsole. Not only is it the lightest design in the collection, it also has the smallest environmental impact. The 'Space Waste Yarn' upper consists of approximately 75% recycled material (by weight) made from recycled plastic bottles, T-shirts and leftover patches of fabric. A soft Crater foam midsole combines Nike Grind with different types of foam for stability and a unique look.
