The Nike Air Force 1 Flyleather Triple Black is a new iteration of the silhouette and upgraded with a sustainable Flyleather material that is made with at least 50% leather fiber. According to Nike, Flyleather is lighter, more durable, and has a lower carbon footprint. This pair looks just like any other AF1, but the sneaker also receives Swoosh branding on the heel tabs and custom insoles that promote the sustainable design.
