With this new silhouette, Nike is promising a shoe that can "do it all" by aiming to offer more cushioning and better energy return in a lightweight package, and to maintain these properties long term. While the shoe's upper is relatively simple with its sculpted Flyknit construction, the tooling has been given a boost. It may look derivative of Adidas' popular foam-based cushioning, but according to Nike, the surface was engineered "to deliver cushioning and support in the specific spots needed during a run, while eliminating material wherever it’s not absolutely necessary in order to keep weight to a minimum." The one-piece foam unit is also softer than traditional EVA, which necessitated a thicker design to prevent bottoming out. The Nike Epic React Flyknit is scheduled to hit retail on Feb. 22. No pricing information is available at this time.
