The Nike Space Hippie 01 ‘Grey Volt’ is a unique addition to Nike's innovative footwear collection, which creatively repurposes discarded materials, or 'space junk,' gathered from their own factory floors. This sustainable approach is demonstrated through the use of recycled plastic water bottles, T-shirts, and yarn scraps in the construction of the engineered knit upper. Furthermore, the Crater Foam midsole is a testament to Nike's commitment to sustainability, as it combines standard foams with 15% Nike Grind rubber. Adding to the shoe's sustainable design, the ZoomX foam insole is crafted using leftover scraps from the production of the Vaporfly 4%. By utilizing these otherwise unused materials, Nike exemplifies their dedication to reducing waste and promoting eco-conscious practices in the fashion industry.
