Nike React Infinity Run Flyknit 4 Running Shoes

With supportive cushioning built for a smooth run, the Infinity Run 4 helps you hit the ground running. Made with soft, comfortable Nike ReactX foam and updated with Nike Running's best-fitting Flyknit yet, this road runner helps you take off any time, anywhere. It's the kind of shoe that can grant you the peace of mind to go faster and further, thanks to high foam stacks and an intuitive, supportive design.

Flyknit Upper

The Nike React Infinity Run Flyknit 4 features a Flyknit upper construction that promotes exceptional breathability and comfort. This design prevents your feet from feeling suffocated, ensuring a comfortable fit. Perforations within the fabrics allow for optimal breathability, keeping your feet feeling fresh while wearing the shoes. Alongside this, a water-repellent lining in the toes provides coverage and protection from light rain and moisture. The Flyknit tongue is easily adjusted and cushioned to help you remain comfortable, preventing irritation and abrasion from occurring during extended runs. Alongside this, the foam collar is exceptionally soft and supportive preventing irritation and abrasion during movement. The shoes have an internal Flyknit fit band that provides your foot with elastic, secure support, preventing feet from slipping around in the shoes. Compared to previous versions the toe box is wider, providing additional room and increased comfort when training. Completing the uppers, the shoes have a traditional lace-up structure, for a secure, locked-in fit, and help to prevent in-shoe movement from occurring.

Nike ReactX Midsole

Providing you with soft, lightweight and durable foam, the shoes utilise Nike ReactX so that you can get even closer to the ground without sacrificing comfort and speed. This, therefore delivers you with feathery durability plus smooth responsiveness. ReactX foam reduces the carbon footprint of the midsole by at least 43% compared to prior Nike React foam, so it helps support the planet too. The reactive nature of this clever midsole material means it absorbs impact and then expels it back out for a bounce-like effect. This energy-return technology reduces superfluous muscle power, diminishes fatigue and enhances performance, keeping you going for longer. Soft, generous, and substantial, React will spare your joints as you strike down onto hard, unforgiving concrete and infuse every stride with the kind of zealous power that is often elusive in the running world. The shoes also have a curved rocker outsole which allows every step to feel more natural, therefore adding efficiency to your run, and helping you to waste less energy as you hit your stride. The midsole offers you flexibility when your foot rises off the ground, a smooth ride when your foot is moving forward and cushioning during ground contact.

Durable Rubber Outsole

Increased rubber on the outsole completes the React Infinity Run 4 providing enhanced traction and increased durability. It ensures a strong grip, works to protect itself from damage and protects users from losing control and slipping. A new waffle outsole pattern has been used on the rubber outsole to enhance multi-surface traction ensuring confident footing wherever your next race takes you.
