The Nike Air VaporMax 2020 Flyknit ‘Obsidian Siren Red’ showcases vibrant accents on a lifestyle runner built with sustainability in mind. Post-industrial recycled yarns make up the composition of the navy Flyknit upper, secured with Barely Volt quick-pull straps connected to the FastFit lacing system. The slip-on silhouette rests on a low-profile one-piece VaporMax unit that runs the entire length of the shoe, offering plush cushioning and a smooth ride.
