The Nike ReactX Infinity Run 4 is designed for adult male runners seeking a balance of high-level responsiveness and daily comfort. Its primary benefit lies in the advanced ReactX cushioning technology, which provides significant energy return to help reduce fatigue during long runs. One caveat to consider is that the structured, supportive design may feel firmer or bulkier compared to minimal racing flats, making it best suited for training miles rather than sprinting.

The ReactX Infinity Run 4 is optimized for road and pavement running. While it can handle light, flat paths, it does not have the deep lugs required for technical trails.
Most users find that Nike trainers fit true to size. If you prefer a bit of extra room for toe splay during long runs, some runners prefer a half-size up.
Depending on your running surface and gait, you can typically expect between 300 to 500 miles of performance from the ReactX foam.
Yes, the insoles are removable, allowing you to insert your own custom orthotics if needed.
ReactX foam is an updated version designed to provide higher energy return while maintaining the same comfort levels, and it is more environmentally conscious in production.
Loosen the laces across the midfoot section and try using a different lacing pattern to distribute pressure more evenly.
Use the extra eyelet at the top of the shoe to perform a runner's loop (heel lock) to secure the ankle.
Rotate the shoes out of your daily rotation for 24-48 hours to allow the ReactX foam to fully expand and recover.
To ensure the best performance, verify your specific UK size, such as the 7.5, to ensure a snug fit that prevents slipping. Upon unboxing, allow the foam to acclimate to room temperature for optimal responsiveness.
