Product Information
Full details
The Nike ReactX Infinity 4 is a premier athletic trainer designed for adult men who prioritize long-term comfort and reliable support during their running and training routines. Featuring the innovative ReactX foam technology, this shoe delivers significant energy return and a smooth, stable ride for daily mileage. While its performance-focused design is excellent for consistent athletes, the supportive structure may feel slightly firmer than dedicated racing shoes, making it best suited for training rather than high-speed sprints.

FAQs
Is this shoe suitable for marathon training?
Yes, the ReactX foam is designed specifically for high-mileage runs and provides the support needed for long-distance training.
Can I put these in the washing machine?
No, machine washing can damage the foam and the structure of the shoe. Use a damp cloth to spot clean.
What is the primary difference between React and ReactX foam?
ReactX foam is a further evolution of the classic React technology, specifically engineered to provide higher energy return.
Are these shoes true to size?
They are designed for a precise fit. If you prefer extra room in the toe box, some users may prefer a half-size up, but they generally fit standard UK sizing.
Are these suitable for wet surfaces?
The outsole provides reliable traction on standard road surfaces, though caution should always be used on slick or icy pavement.
Troubleshooting
Feeling of excess pressure in the midfoot
Try adjusting the lacing technique to a parallel lacing style to relieve pressure while maintaining lockdown.
Outer sole picking up small debris
Regularly inspect the tread pattern after runs and gently remove trapped pebbles with a blunt tool.

Setup, Compatibility & Care
To ensure the best experience, verify your specific UK size, as the ReactX Infinity 4 is designed with a precise fit; it is recommended to wear standard performance socks to maintain this sizing accuracy. Compatibility is highest on paved surfaces and gym flooring. For care, keep the trainers away from excessive heat to prevent foam degradation. Clean the surface with a soft, damp cloth and mild soap; do not submerge in water or place them in a washing machine, as this can damage the structural adhesives and foam integrity.
