From the upper to the outsole, the Nike Space Hippie 01 “Vast Grey” is made of 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. The Space Waste Yarn upper assumes a “Vast Grey” coloring, allowing for the aforementioned green applied to the lace loops and stitched profile Swooshes to stand out. Black loops on the heel and tongue further create a graphic look. The eco-conscious style is complete with a chunky Crater foam sole, which sees a speckled design that differs with each pair.
