Midsole

The midsole of this shoe is made of React foam. For this foam, Nike combined different polymers: thermoplastic elastomer (TPE) and ethylene vinyl acetate (EVA). The Nike React foam provides a lot of cushioning and is very responsive due to this unique combination. Nike uses this foam specifically to reduce the risk of running-related injuries. The Nike React foam is therefore one of the most complete foams from Nike. 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. Instead of laces, this shoe uses Flywire technology, which uses high-tensile strength wires that function to provide ultimate precision support.
