Nike's revolutionary runner is back in a sleeker look! Nike Vapormax 2021 Flyknit boasts of lightweight, durable construction and Vapormax cushioning like its predecessors with a little tweak in function and aesthetics. Its design utilizes recycled polyester, foam, and a Nike Air sole made from at least 75% recycled TPU. Hard to believe, this beauty is part-trash! Foam tongue gives a soft and comfortable feel. TPU heel and toe clip provides a secure fit and adds durability.
