FAQs
Is the ReactX Infinity Run 4 suitable for trail running?
These shoes are designed primarily for road and pavement use; the outsole does not have the deep lugs required for technical trail terrain.
How do I know if the UK size 13 fits correctly?
You should feel a snug hold in the midfoot with enough room in the toe box to wiggle your toes comfortably.
Can I use these for marathon training?
Yes, their stable design and cushioning make them an excellent choice for the high-mileage training weeks required for marathon preparation.
What is the primary difference between ReactX and standard React foam?
ReactX foam is engineered to provide higher energy return and a more responsive feel, while maintaining the signature softness of the original React foam.
Are these shoes machine washable?
No, machine washing can damage the adhesives and the cellular structure of the foam. Manual cleaning is recommended.
Does this shoe offer arch support?
The ReactX Infinity Run 4 is designed with a stable geometry that provides inherent support suitable for a wide variety of foot types.
Troubleshooting
Visible dirt or mud on the upper
Use a soft-bristled brush to remove dried dirt, then wipe the fabric with a cloth dampened with water and mild detergent.
Shoes feel tight after a long run
Your feet naturally swell during exercise. Ensure you are wearing appropriate running socks and consider loosening the lacing system during your run.
Foam starting to show creases
Creasing is a normal characteristic of performance foams due to compression. It does not typically indicate a loss of performance or structural integrity.

Setup, Compatibility & Care
To ensure the longevity of your trainers, focus on proper fit and routine maintenance. When you first receive the shoes, ensure you have approximately a thumb's width of space at the front of the toe box for comfort during foot swelling on long runs. For care, avoid putting your trainers in the washing machine, as the heat and agitation can degrade the foam properties. Instead, wipe the exterior with a damp cloth and mild soap. If the insoles become wet, remove them and allow them to air dry in a well-ventilated area away from direct sunlight.
