The Air VaporMax 2020 Flyknit 'Summit White' brings a neutral look to its bold, sustainable construction. The shoe's Flyknit upper is built with recycled polyester yarns, supported by FlyEase technology in place of traditional laces. Tongue and heel pull-loops provide easy on and off, while the molded heel counter, built with 60% recycled TPU, sports a swirling design. Underfoot, the VaporMax unit, also built with recycled TPU, provides cushioning.
