The Nike Epic React Flyknit White is loaded with state of the art technology from heel to toe. The Epic React Flyknit Running Shoe is the first to feature Nike’s proprietary React Foam, which has been specifically designed to offer better cushioning and better energy return, while also being lightweight and durable.
Nike React foam is significantly softer than EVA-based foams of the past and so it smooths bumps in the road more effectively. The midsole is taller in order to avoid “bottoming-out” and wider to give runners a supportive base. Designers extended the midsole beyond the perimeter of its upper and around the heel to provide both the cushioning and stability needed.
