Details & care
Nike's supercharged ReactX foam amps the energy return under a new-generation running shoe that still delivers the plush, smooth ride of earlier iterations.
Perfect for: Runners looking for a supportive, well-cushioned ride that transforms every stride into returned energy to help increase speed without increasing effort.
Upper: Internal FlyKnit fit band locks your foot in place and moves comfortably to provide stretchy, secure support. Wider toe box allows for unrestricted movement and toe spread on longer runs. Water-repellent toe keeps splashes and moisture at bay.
Midsole drop: 9 mm. Classified as a high-drop measurement, it allows for more cushioning to absorb the impact of heel strikes.
Lower: Springy ReactX foam amps up energy return while minimizing environmental impact. Tuned support and targeted cushioning efficiently transition every stride from heel strike to toe-off. Waffled rubber tread puts traction and confidence under every stride.
- Cushioning: absorbs impact and distributes weight for consistent, buoyant comfort under each step
- Support: enhances the fit with targeted contouring and cushioning in the footbed
- Energy return: transforms every heel strike into responsive, explosive forward movement
- Lace-up style
- Flyknit upper provides a snug, socklike fit that flexes with every movement
- Removable, cushioned insole allows for custom orthotics
- Nike ReactX foam provides more energy return than Nike React foam and leaves a smaller carbon footprint under every step
- Synthetic and textile upper and lining/rubber and synthetic sole
- Imported

My favorite Nike running shoes
The Nike InfinityRN 4 is one of my favorite Nike running shoes out there. For runners looking for a cushioned, durable, and stylish road running shoe. With Nike’s ReactX foam, it offers a noticeably softer and more responsive ride compared to previous models, making long runs more comfortable. The Flyknit upper provides a snug yet breathable fit, and the wider forefoot adds extra stability.
While the shoe excels in comfort and daily training, some runners may find it a bit bulky for speed workouts. However, if you prioritize impact protection and smooth transitions, the InfinityRN 4 is a reliable option for casual and serious runners alike.
Pros:
✔️ Soft and responsive ReactX foam
✔️ Breathable Flyknit upper
✔️ Stable and supportive for long runs

Change colors when wet.
First. Review process is too much. Shopping in app takes you to a website which forces you complete almost 10 steps just to do a simple review.
Anyways. Shoes are comfortable, but as soon as they get just a little water or rain on them, they turn purple.

Color is completely different from website photos
The color of the olive model of these sneakers is dramatically different in the website photos than it is in person. See photo taken of shoes once received. Pretty disappointed in this discrepancy, the color is more of a sage/pale green than olive.

I bought a pair when the shoe first came out and I loved them but after buying my second pair a year later, the fit isn’t as great as the first pair and the material seems a bit different.

Great shoe for ancient aging knees
Great shoe. After 100,000+ miles of running over 65+ years this, shoe with great cushioning and stability, is the only reason I am able to continue running.

This is my third pair. They fit like a glove! Very durable and comfortable for all day wear.
