The Epic React Flyknit is Nike's latest running shoe, and may point to a new range of performance shoes. Replacing the Lunar Epic Flyknit, the Epic React Flyknit advances overall performance with a focus on a new midsole technology.
The upper is a monosock design, a new version of Flyknit which is quite thin with no additional ankle collar padding, welded overlays reinforce the eye stay, and a TPU heel counter adds a little structure. The stretch of the Flyknit, as well as the laces, do an excellent job of securing the foot, with no pressure, slippage, or discomfort. The React midsole material is a proprietary foam developed specifically by Nike, dialed in after hundreds of chemical combinations. The ride has a resilient bounce to it, is durable, as well as protective. The outersole features crystal rubber at heel and toe, with the rest a tough skinned foam. The weight of the shoe is quite light, noticeably lighter than the Lunarlon foam that it replaces. While the price tag has placed the shoe in the premium range, the performance matches it, and the promise of more to come may well point to something for everybody.
