Midsole

The midsole is made of React foam, a combination of thermoplastic elastomer and ethylene vinyl acetate (EVA) that Nike combined to create the Nike React foam. This unique combination makes the Nike React foam provide great cushioning and responsiveness. Nike uses this foam to minimize running injuries, making it one of Nike's most complete foams.

Upper

In the upper, the shoe has a Flyknit material made from strong, yet lightweight yarns. The midfoot is reinforced with a denser fabric, while the forefoot is flexible and breathable. Flywire technology replaces laces with high-tensile wires that act like suspension bridge cables and provide precise support.
