Still one of our most tested shoes, the Nike React Infinity Run Flyknit 2 is designed to help you feel the potential when your foot hits the pavement. A refreshed upper uses Flywire technology combined with Flyknit fabric to give you support and breathability where you need it. The high foam heights provide soft responsiveness and long-lasting comfort.
Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. Shaped like a rocker, the foam provides support for the 3 phases of a runner's stride. It offers flexibility when your foot rises off the ground, a smooth ride when your foot is moving forward and cushioning at ground contact.
Ventilated Where Needed
An evolved Flyknit upper has breathable zones right where you need them. It's strong and durable, helping to keep your foot secure mile after mile. Flywire technology offers extra support and stability through the midfoot.
Cushioned Feel, Higher Stacks
Less material between the insole and midsole means you're closer to the foam. This helps create a more responsive experience. The foam itself has a higher height, providing a softer feel.
Celebrate the Swoosh
Nike celebrates its 50th anniversary by intertwining the past and present. The original Swoosh is outlined over the current version, representing the path Nike has taken from yesterday to today.
A wide shape provides a more stable ride, helping release energy with every step.
Cushioned collar provides soft comfort.
More rubber at the outsole helps give you traction and durability.

Testing shows* that the Nike React Infinity Run 2 reduces injuries at a similar rate as the Nike React Infinity Run, which, in a separate study, was shown to reduce injuries by 52% compared to the Nike Air Zoom Structure 22, our traditional motion control shoe. *In an external study of 226 men and women during a 12-week variable training program conducted in 2019, the Nike React Infinity Run reduced running injuries by 52% compared to the Nike Air Zoom Structure 22 (injury = missing 3 or more consecutive runs due to running related pain). Participants reported on progress and injuries via online questionnaires. Our study found that 30.3% of Nike Air Zoom Structure 22 runners experienced an injury but only 14.5% of Nike React Infinity Run runners experienced an injury. In a second study conducted in 2020 using the same protocol, Nike React Infinity Run 2 showed no statistically significant difference in the incidence of injuries over the previous year’s Nike React Infinity Run model.
