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. The dual-density midsole (firm foam on the outside and soft foam on the inside) provides responsive cushioning for long-lasting comfort. The midsole is also made of sustainable materials.

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. Thanks to the FlyEase technology, the shoe is extremely easy to put on and take off. You can open the shoe with a zipper on the heel and a strap over the top ensures a snug fit. Light textiles provide ventilation to keep you cool. The heel overlay provides support and stability during multi-directional twists. Flywire technology replaces laces with high-tensile wires that act like suspension bridge cables and provide precise support.
