NIKE REACTX

Nike ReactX foam reduces the carbon footprint of the midsole by at least 43% compared to prior Nike React foam, so it helps support the planet too. ReactX foam gives you +13% energy return compared to React foam, helping you stay fresh and bouncy during your run.

FLYKNIT

An innovative upper material, constructed entirely of tightly woven polyester yarn that varies in density: more open in targeted areas that need greater flexibility or ventilation and tighter in areas that demand support. Precise knit construction process integrates stretch and support for a more exact fit.
