The Nike Space Hippie 01 ‘Carbon Green’ pairs sustainable construction with a tonal color palette. Varying shades of green are applied to a sock-like Flyknit upper made with a blend of recycled water bottles, T-shirts and yarn scraps. An embroidered Swoosh decorates the minimalist build, secured with rope laces integrated into stitched-on webbing eyestays. Neon green pull tabs at the tongue and heel deliver easy on and off. The sneaker is mounted on a speckled Crater Foam midsole, made with approximately 11% Nike Grind rubber and standard foam materials.
