Midsole

The shoe has a React foam midsole made of ethylene vinyl acetate (EVA) and thermoplastic elastomer (TPE). This unique combination of polymers ensures that Nike React foam is very responsive and cushioning. This foam is specially designed to reduce the risk of injuries while running. This makes the React foam one of the most complete foam types currently available.

Upper

The upper of the shoe is made of Flyknit. This is made from strong, but lightweight yarns woven into one piece. The midfoot is reinforced with a denser weave, while the forefoot is flexible and breathable. Instead of laces, the shoe features Flywire technology, made from high-tensile wires used in suspension bridges and providing ultimate precision support.
