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.
The forefoot, toe and arch are very sculpted thanks to the one-piece Nike Flyknit bootie (which takes cues from the Nike Flyknit Racer) that was precision-engineered for support, flexibility and breathability in the spots where runners need it. It’s minimal and close to the foot but still supportive.
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.
Because the upper sits on one piece of foam, the outsole is essentially the same as the midsole, but with a segment of rubber under the forefoot and heel for added traction and to help enhance the shoe’s durability.
- The one-piece Nike Flyknit bootie has been precision-engineered for support flexibility and breathability.
- The midsole extends beyond the upper around the heel to provide the cushioning runners want and the stability they need.
- Deeper parts on the midsole and outsole indicate areas of more cushioning and shallower portions produce more firmness.
