Nike React Infinity Run Flyknit 4 Running Shoes

Hit the ground running and leave all your worries in the rearview with the React Infinity 4s. Instilled with soft cushioning and updated with the best Flyknit yet, you can take off anytime, anywhere without all that wear-and-tear attrition living rent-free in the back of your brain.

Flyknit Upper

The Nike React Infinity Run Flyknits feature 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 you with coverage and protection from light rain and moisture. The Flyknit tongue is easily adjusted and is cushioned to help you remain comfortable, therefore preventing irritation and abrasion being caused during extended runs. Alongside this, the foam collar is exceptionally soft and supportive further preventing irritation and abrasion during movement. The shoes have an internal Flyknit fit band, which 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 you with 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 the use of superfluous muscle power, diminishing fatigue and enhancing 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 forwards and cushioning during ground contact.

Durable Rubber Outsole

Increased rubber on the outsole completes the React Infinity Run Flyknit 4 Running Shoes to provide enhanced traction and increased durability. It ensures a strong grip and works to protect itself from damage, and protects users from losing control and slipping.
