Made from at least 40% recycled materials by weight, the Nike Air VaporMax 2021 FK is airy and easy to wear with super-stretchy, recycled Flyknit fabric, plus a soft collar that sculpts your ankle.The stitched-on Swoosh and recycled TPU heel clip add a splash of intrigue as you float down the streets on incredibly soft VaporMax cushioning.Like New, after few wears I found out that these sneakers are not designed for people with FLAT FEET, so I decided to sell it
