The Nike Space Hippie 04 is composed of at least 25% recycled material by weight making it the lightest model from the collection and also has the lowest carbon footprint. This pair gets equipped with an all-White “Space Waste Yarn” upper that includes about 75% recycled content by weight-made from recycled plastic bottles, t-shirts and yarn scraps. Down below we see the signature Crater Foam midsole and outsole to wrap things up.
