The Nike Space Hippie 01 ‘Electric Green’ adds fluorescent accents to a lifestyle sneaker composed of at least 50% recycled materials. The sock-like FlyKnit upper is made with Space Waste Yarn — 100% recycled material that includes plastic water bottles, T-shirts and yarn scraps. In lieu of a traditional eyestay, laces are integrated into neon green cords stitched directly onto the upper. Matching green yarns are woven into the side panels to form the signature Swoosh. Lightweight cushioning arrives via a Crater Foam midsole, featuring a blend of Nike Grind and standard foams compounds.
