Gently Used. The Nike Cosmic Unity Space Hippie is made of sustainable materials. It is dressed in Chambray Blue and Particle Grey color tones. It features Particle Grey shades while the midsole extends to the heel and the outsole comes in Chambray Blue hue. The Nike text logo on the tongue is embedded on a Space tag, while the Swoosh is featured on the medial side and on the top eye stays in orange. Almost every component of the shoe is made of recycled materials, including the full-length Zoom Air Strobel and Crater Foam midsole, which are both partially made of recycled TPU and stitched onto the layered textile top. This variant has a very tough rubber outsole. Our experts think the unique aspect of the Space Hippie line is in its innovative use of recycled materials, such as Nike Grind rubber, recycled foam scraps, and recycled yarn, in the construction of the shoe. The Nike Cosmic Unity Space Hippie was released on March 12, 2021. The pair initially retailed at the price of $150.
