Nike InfinityRN 4
With supportive cushioning built for a smooth run, the InfinityRN 4 helps you hit the ground running. Made with soft, comfortable Nike ReactX foam and updated with Nike Running's best-fitting Flyknit yet, this road runner helps you take off anytime, anywhere. It’s the kind of shoe that can grant you that priceless peace of mind to go faster and farther, thanks to high foam stacks and an intuitive design that supports every stride.
Cushioning: Super High
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.
Support: High
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. A new internal Flyknit fit band (like a rubber band around the middle of your foot) offers elastic, secure support.
Responsiveness: Moderate
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.
What's New About the Nike InfinityRN 4?

Great road running shoe
Babak - Aug 30, 2024
Love these road running shoes. Love them so much, I have purchased 6 of them in the past 3 mos. The cushioning and all around look & feel of these shoes are amazing. I highly recommend this shoe to any avid city runner.

Nice toe room. Lack of lock-down below the top of the foot. Not a lot of pop/energy-return. Bottoms-out quickly. Good arch support. Too squishy if you've got metatarsal sensitivity. I'm glad I stocked up on previous React cushioning models.. I think React's more durable/comfortable, overall.
