FAQs
Are these shoes good for marathon training?
Yes, the ReactX Infinity Run 4 is specifically engineered for long-distance running, providing the support and cushioning necessary for high-mileage training.
Can I use these for trail running?
These trainers are designed primarily for road running. They lack the aggressive lug patterns and protective rock plates required for safe technical trail running.
How often should I replace these shoes?
Generally, running shoes should be replaced every 300 to 500 miles, depending on your running surface and biomechanics.
Do they provide arch support?
The shoe is built with a stable base that provides neutral support, which is suitable for most runners needing a secure, cushioned ride.
How do I clean the white fabric?
Spot clean with a soft brush and mild soap. Avoid high heat or direct sunlight when drying to prevent material yellowing or damage.
Troubleshooting
Feeling of decreased responsiveness
Foam may be compressed from back-to-back runs; rotate with another pair to allow the foam to decompress for 24-48 hours.
Visible dirt on the white upper
Use a soft-bristled brush with a mixture of warm water and mild soap to spot clean, then air dry away from direct heat sources.
Slipping inside the shoe
Re-lace the shoes using the top eyelet (runner's loop) to secure the heel and improve overall lockdown.

Setup, Compatibility & Care
To ensure the longevity of your Nike ReactX Infinity Run 4, proper care is essential. Since the upper is primarily white, it is recommended to spot-clean the fabric with a soft brush and mild detergent after runs in dusty or muddy conditions. Avoid submerging the shoes in water or using a washing machine, as this can degrade the foam and adhesive integrity. Rotate your shoes with another pair to allow the foam to fully decompress between runs, which significantly extends the lifespan of the cushioning system. Ensure you are wearing the correct size, as a proper fit is critical to the shoe's stability features.
