Product Information
Full details
The Nike ReactX Infinity 4 trainers are designed for adult male runners seeking a balance of high-level cushioning and reliable support for daily mileage. Featuring the advanced ReactX foam, these shoes provide significant energy return and a smoother transition through every stride, making them an excellent choice for injury-prevention-focused training. However, the substantial cushioning profile may feel slightly bulky to runners who prefer a minimal or lightweight racing-style shoe.

FAQs
Are these shoes suitable for high-arch feet?
Yes, the ReactX Infinity 4 provides a supportive structure that works well with a variety of foot types, including high arches.
Can I use these for trail running?
These shoes are designed primarily for road and light pavement running; they lack the aggressive lugs necessary for technical trail terrain.
How often should I replace these trainers?
Generally, it is recommended to replace running shoes every 300 to 500 miles, depending on the intensity and surface of your runs.
Are they waterproof?
No, the trainers feature a breathable mesh upper that is not waterproof.
Does the ReactX foam lose its bounce?
ReactX foam is engineered for long-term durability and retention of energy return compared to traditional EVA foams.
Troubleshooting
Feeling of stiffness out of the box
The foam requires a short break-in period of 10-15 miles to fully adapt to your foot strike and flexibility.
Build-up of debris in the tread
Use a specialized shoe brush or a toothpick to gently dislodge gravel or small stones from the outsole grooves.

Setup, Compatibility & Care
To ensure the longevity of your Nike ReactX Infinity 4 trainers, it is essential to follow a few maintenance steps. Ensure you are wearing the correct size, as this model is specifically calibrated for a secure fit in UK size 9.5. To clean, remove loose dirt with a soft brush and wipe the mesh upper with a damp cloth and mild soap; avoid machine washing or drying, which can compromise the foam integrity. Allow the shoes to air dry naturally away from direct heat sources.
