Introducing Nike's all-new Space Hippie collection - one big step with a small footprint. From top to bottom, the Space Hippie 04 is made of at least 25% recycled material, and as well as being the lightest silhouette within the collection, it also has the lowest carbon footprint. Its 'Space Waste Yarn' upper utilises around 85% recycled polyester, made up from a mix of recycled plastic bottles, tees and factory floor scraps. On the underside, the eco-theme continues Nike's innovative 'Crater Foam' midsole which fuses a combination of standard Nike foams, 15% NikeGrind rubber and recycled ZoomX foam for responsive cushioning and a unique aesthetic.
