Nike’s Epic React was unveiled in January of 2018 and launched the following month as what was essentially the Swoosh’s answer to the UltraBOOST. The first shoe to employ Nike’s energy-returning React foam cushioning, the Epic React is billed as a running shoe that can do it all and pairs the proprietary sole unit with a simple one-piece Flyknit bootie inspired by the Flyknit Racer. Because React is significantly softer than traditional EVA-based foams, Nike made the midsole both taller and wider than more prototypical designs to prevent bottoming-out during runs. The Swoosh also used computational data-driven ideation to design the midsole, which allowed Nike to keep weight to a minimum and ditch any carrier, cement or glue.
