The Nike Space Hippie 04 Mystic Navy is inspired by the concept of utilizing materials that would otherwise go to waste and giving them a second life, reflecting the ethos of the Space Hippie movement. This model features a woven texture on the upper with a sole made from Nike's proprietary ZoomX foam, sourced from foam scraps collected at Nike factories. The incredibly lightweight ZoomX foam offers excellent cushioning and energy return, while the outsole, crafted from Nike Grind material, is durable and provides superior traction across various surfaces, all while reducing the carbon footprint. A highlight of the Nike Space Hippie 04 Mystic Navy is its unique construction, featuring a partially translucent upper made from recycled materials, including plastic bottles, t-shirts, and yarn scraps. Released on December 8, 2020, at a retail price of $130, this model is notable for its cool color palette and commitment to sustainable design, utilizing asymmetrical lacing with a Flyknit upper made from recycled yarns. The speckled Crater Foam midsole effectively combines Nike grind rubber with standard foam compounds.
