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 is made of Nike Flyknit. This is made of strong, but light yarns that are woven into one whole. Around the midfoot the material is more densely woven to provide support, while at the forefoot the material is made flexible and ventilated. Flywire technology replaces laces with high-tensile wires that act like suspension bridge cables and provide precise support.
