Nike just introduced their brand new Nike Epic React Flyknit. Not only is it a new model, it’s also the first Nike running sneaker to utilize Nike’s React technology.

The Nike Epic React Flyknit features Nike’s latest foam technology designed to cushion the impact of each stride and offer the energy return needed to stay fresh late in a run. The design of the shoe consists of a forefoot, toe and arch with the help of the one-piece Nike Flyknit bootie that is precision-engineered for support, flexibility and breathability in areas where we need it most. It is minimal and close to the foot but still supportive.

Nike React foam is significantly softer than EVA-based foams used in past models. So whenever you hit a bump on the road, it manages to smooth it out more effectively. In addition, the midsole had to be taller in order to avoid “bottoming-out” and wider to give runners a supportive base. To solve for that, designers extended the midsole beyond the perimeter of its upper around the heel to provide both the cushioning runners want and the stability they need.

Computational design, which enables rapid data-driven ideation, was used to create the midsole, which is one piece of Nike React foam (with no carrier, cement or glue). This method allowed for engineering the surface of the midsole 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 visually complex pattern varies in depth, where deeper parts indicate areas of more cushioning and shallower portions produce more firmness.

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.
