Men's Nike React Infinity Run 4



Elevate your runs with the Nike InfinityRN 4—one of the best running shoes from Nike.

Featuring Nike ReactX foam, the InfinityRN 4 delivers a remarkable 13% more energy return than its predecessor to give you an even more responsive and bouncy ride. Beyond your run, this innovative foam also reduces the midsole's carbon footprint by 43% (so it supports your feet and the planet).

Nike’s breathable Flyknit upper keeps your foot locked in and supported during your workouts, while the curved outsole with a wide base smoothly rolls your foot forward to make each stride feel stable and effortless.


  • Upper: An internal Flyknit fit band around the middle of your foot offers elastic, secure support. The Flyknit tongue is adjustable and plush, while the foam collar is soft and supportive to the touch. Plus, a water-repellent liner in the toe helps keep you dry if the weather turns.
  • Midsole: ReactX foam gives you 13% more energy return compared to React foam for an incredibly smooth feeling. A curved outsole and intentionally placed cushioning gives you a stable base to help your feet rock smoothly from heel to toe.
  • Outsole: Waffle outsole provides durable traction
