A supportive and cushioned shoe built for a smooth run on any terrain.

With supportive cushioning built for a smooth run, the Nike InfinityRN 4 is a brand-new take on a familiar favorite. It's made from our all-new Nike ReactX foam, which gives you 13% more energy return compared with Nike React foam, to help you stay fresh and bouncy. (What's more? Nike ReactX reduces its carbon footprint in a pair of midsoles by at least 43% compared to Nike React foam.*) This version has GORE-TEX fabric to help you stay dry for your miles. It’s the kind of shoe that supports every step in style.

*The carbon footprint of ReactX is based on cradle-to-gate assessment reviewed by PRé Sustainability B.V and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered.

What's New About the Nike InfinityRN 4?

This version of the Nike InfinityRN 4 still provides a plush and smooth ride, with ReactX foam delivering more support. The wider toe box helps your foot feel stable and secure.

• Dry Design:Waterproof GORE-TEX fabric helps keep you dry so you can focus on the adventure.
• Super High Cushioning:The more cushioning that you have underfoot, the softer and more comfortable your running experience can be. Cushioning helps soften impact as your feet hit the ground. ReactX foam gives you an incredibly smooth feeling, helping you push your limits.
• High Support:The more supportive the shoe, the more stability it can give to your natural stride. A combination of tuned support and intentionally placed cushioning helps you feel secure with every step. A curved outsole helps your foot rock smoothly from heel to toe and through your stride to footstrike. It makes every step feel more natural and adds efficiency to your run, helping you waste less energy as you hit your stride.
• Responsiveness:The more responsive the shoe, the more energy return you can get back with each step. Whether you want to run a little bit faster or with a little less effort, responsive shoes help give you slightly more spring in your step to get more out of your run. ReactX foam gives you 13% energy return compared to React foam, helping you stay fresh and bouncy during your run.
• Reliable Traction:A Storm Tread outsole provides reliable traction on wet and slippery surfaces. The rubber wraps around the front of the shoe for extra durability. Its generative traction pattern combined with rubber lugs gives you grip when going uphill or downhill.
