Midsole

The midsole is made of React foam, which consists of a combination of thermoplastic elastomer (TPE) and ethylene vinyl acetate (EVA). Nike's React foam provides a lot of cushioning and is extremely responsive thanks to this unique combination of polymers. It is specifically used by Nike to prevent running injuries. As a result, Nike React foam is one of the most complete foams 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.
