The Nike Air VaporMax 2021 Flyknit ‘Monochrome’ brings together buoyant cushioning and a sustainable build, featuring 40% recycled content by weight. Outlined in black embroidery, a stitched-on Swoosh decorates the pale grey Flyknit upper, composed of recycled polyester and equipped with a stretchy sock-like cuff. A molded heel clip made with recycled TPU offers rearfoot stability. The lightweight build rests on a one-piece VaporMax unit, supported underfoot by a speckled Nike Grind outsole.
