Performance running heritage goes green! Made from at least 40% recycled material by weight, the Nike Air VaporMax Flyknit 2021 is airy and easy-to-wear. Originally designed for running, this Nike Air features a super stretchy recycled FlyKnit, a soft, seamless collar that sculpts your ankle, and the 1st one-piece Air unit that runs the entire length of the shoe. The FlyKnit upper is made from post-industrial recycled yarn and offers a lightweight, seamless, breathable feel while the recycled TPU heel clip adds heritage styling to the sneaker. Its classic-meets-modern construction is evident in the traditional lacing system flattered by the modern webbing eyelets. Nike Air VaporMax Flyknit 2021 features: • Regrind rubber details provide traction and durability. • The lacing system provides ease of entry and the padding on the heel adds to the comfort. • The Air unit provides cushioning and allows for smoother transitions. • The recycled rubber on the sole adds durability and traction
