Nike has just unveiled its late innovation in running, its new runner: the Epic React Flyknit.

The shoe boasts a new foam React cushioning, which will replace the usual EVA foam.

Before delivering to market, the new technology was tested for a total of 17,000 miles by Nike’s best runners. It is lighter, softer and offers greater “energy return” than the first model, the Lunar Epic 2.

The Epic React Flyknit features a one-piece Nike Flyknit bootie upper, engineered for support, flexibility and breathability where it’s needed the most.

Both the midsole and outsole are a single piece of Nike React foam, with rubber underneath for grip and traction.
