FAQs
Is the Nike ReactX Infinity 4 suitable for trail running?
These trainers are primarily designed for road and gym surfaces. The outsole pattern is not aggressive enough for loose or uneven trail terrain.
How does ReactX foam differ from standard React foam?
ReactX is an updated formulation that provides higher energy return and improved responsiveness while maintaining a lightweight feel.
Can I use these for cross-training?
Yes, their stable platform makes them suitable for general gym workouts, though they are primarily optimized for linear running movements.
How do I determine if size 10.5 fits correctly?
You should have approximately a thumbnail's width of space between your longest toe and the front of the shoe.
How often should I replace these trainers?
Generally, running shoes like these should be replaced every 300-500 miles, depending on your running style and surface conditions.
Troubleshooting
Shoes feel slightly tight after long runs
Feet often swell during exercise; consider loosening the lacing system during the latter half of your workout.
Dirt buildup on white sole accents
Use a damp microfiber cloth with a small amount of dedicated sneaker cleaner to wipe away debris immediately after use.
Slippage during intense movement
Ensure the heel is fully seated in the counter and utilize the top eyelet to create a 'runner's knot' for a more secure lock-down.

Setup, Compatibility & Care
To ensure the best fit, ensure you are wearing the appropriate athletic socks you intend to use for training, as this can affect the sizing feel. The ReactX Infinity 4 fits true to standard Nike sizing. For maintenance, keep the shoes away from extreme heat sources, such as radiators, which can degrade the foam chemistry. To clean, use a soft-bristled brush and mild soap with lukewarm water; air dry naturally in a shaded, well-ventilated area. Avoid machine washing or tumble drying, as these processes can damage the adhesive components and structural integrity of the upper.
