Nike Space Hippie 03’Grey Volt’ is based on a series around sustainability and radical design themes. This pair adopts high-cut collar and innovative FlyEase technology, which is easy to insert and fit firmly. The knitted upper is made of Space Waste Yarn with recyclable plastic water bottles and T-shirts, while the Crater Foam midsole combines standard foam with Nike Grind rubber. The regenerated ZoomX foam midsole provides a comfortable riding experience. At the foot, an angled midsole component was created by Nike’s other brand-new sustainable technology “Cratter Foam”, which incorporates the remaining fragments of ZoomX technology and other recyclable materials. If you are looking for a pair of practical shoes with high specifications, then these shoes are enough!
