The Nike Space Hippie 01 Carbon Green showcases a sustainable design with a knit upper composed of around 90% recycled polyester derived from various recycled Nike products, including t-shirts and bags. The sneaker features a responsive Crater foam sole that offers both stability and comfort. Released in October 2021 with a retail price of $130, it combines a sock-like Flyknit upper made from recycled water bottles, T-shirts, and yarn scraps. The tonal green color palette, including shades from dark to neon green, is complemented by an embroidered Swoosh and rope laces integrated into webbing eyestays for a secure fit. Neon green pull tabs at the tongue and heel provide easy on and off, while the speckled Crater Foam midsole is constructed with approximately 11% Nike Grind rubber and standard foam materials.
