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 durable materials.

Upperwork

The upper of the shoe is made of Flyknit, a material that uses a weaving technique to provide support. 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.
