Just like all other models from the Nike Space Hippie Line, the Nike Space Hippie 01 is made of at least 50% recycled material by weight. It starts off with a “Space Waste Yarn” upper that is made up of 90% recycled polyester made from recycled plastic bottles, t-shirts and yarn scraps. The tonal upper is accented by the Dark Grey stitched Swooshes, while Black pull tabs atop its signature chunky Crater Foam sole round out the main features of the sneaker.
