Nike InfinityRN 4 "Pro Green" FZ4019-100

The Nike InfinityRN 4’s ReactX foam delivers an incredibly smooth feeling underfoot, softening the impact as your feet hit the ground. This plush cushioning not only enhances comfort but also helps you push your limits, ensuring a softer and more comfortable running experience with every step.

Experience stability like never before with the high support offered by the Nike InfinityRN 4. A combination of tuned support and intentionally placed cushioning ensures that you feel secure with every stride. The curved outsole allows your foot to rock smoothly from heel to toe and through your stride to footstrike, making every step feel more natural and efficient. Additionally, a new internal Flyknit fit band provides elastic, secure support, wrapping around the middle of your foot like a rubber band to keep you stable and secure throughout your run.

While the Nike InfinityRN 4 offers moderate responsiveness, it still delivers impressive energy return with every step. ReactX foam provides a +13% increase in energy return compared to React foam, ensuring that you stay fresh and bouncy throughout your run. Whether you’re aiming to run faster or simply want to conserve energy, the InfinityRN 4 gives you that extra spring in your step to get more out of your run.
