If you are looking for a reliable neutral all-round running shoe, the Nike React Infinity Run Flyknit 4 is the shoe you need! No matter what pace you run - a 5k or a long run - you can rely on the React Infinity Run Flyknit shoe. Choose versatility and reliability with this all-round running shoe!
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. The midsole is made from a combination of firm foam and soft foam made from durable material for responsive cushioning for long-lasting comfort.
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.
Outsole
The shoe has a rubber outsole and provides good grip and traction while running. The Nike React Infinity Run Flyknit 4 is the all-rounder that will boost your running experience!
