The sleek new Nike Air VaporMax 2020 FK (£190) is designed with sustainability at the core. Despite the fact that a majority of Nike's existing sneakers are not entirely sustainable, the VaporMax 2020, along with other select styles, is a step in the right direction. Made from at least 50 percent recycled content by weight, and a Nike Air-Sole made from at least 75 percent recycled thermoplastic polyurethane, this silhouette is a small step in Nike's wider journey to zero carbon and zero waste.
