The Nike Air VaporMax 2021 Flyknit ‘Triple Black’ presents a monochromatic rendition of a lifestyle runner predicated on comfort and sustainability. A stitched-on Swoosh adorns the black Flyknit upper, composed of post-industrial recycled yarn and supported with a recycled TPU heel clip. Dual pull tabs and an elastic sock-like collar enable easy on and off. The sneaker sits on a low-profile Air-sole unit that runs the length of the rubber outsole, made in part with Nike Grind.
