Full details

FAQs

Are these shoes suitable for flat feet?

The ReactX Infinity Run 4 is designed with a stable geometry that provides inherent support, which many runners with flat feet find beneficial.

Can I use these for trail running?

These trainers are optimized for road surfaces and paved paths; they lack the aggressive lugs required for technical trail terrain.

How often should I replace these trainers?

Generally, running shoes should be replaced every 300 to 500 miles depending on your running surface and weight.

Is the material waterproof?

The upper is designed for breathability, meaning it is not waterproof and will absorb water in wet conditions.

Do these run true to size?

They generally follow standard Nike sizing; if you prefer extra room for foot swelling during long runs, some users prefer a half-size up.

Troubleshooting

Foot discomfort or pressure points

Try adjusting the lacing pattern to a 'runner's loop' to secure the heel without putting excessive pressure on the midfoot.

Foam feels less responsive after many miles

Check the tread wear. If the outsole rubber is worn smooth, the midsole foam may have reached the end of its intended performance lifespan.

Difficulty cleaning light-coloured mesh

Use a specialized sneaker cleaning solution and a soft brush, focusing on small circular motions rather than scrubbing.

Pros and Cons

Pros

  • Excellent energy return from ReactX foam
  • Stable and supportive ride for daily miles
  • Versatile aesthetic suitable for workouts and casual wear
  • Responsive cushioning reduces impact fatigue

Cons

  • Slightly heavier than dedicated speed-racing shoes
  • The stability-focused architecture may feel restrictive to some neutral runners
  • Limited to road and light gym use

Setup, Compatibility & Care

To ensure the longevity of your ReactX Infinity Run 4 trainers, it is recommended to allow the foam to decompress for 24 hours between long runs. For cleaning, use a soft-bristled brush or damp cloth with mild soap to wipe away surface dirt; never machine wash or tumble dry your trainers, as high heat can damage the foam properties and adhesive bonds. Ensure the shoes are stored in a cool, dry place away from direct sunlight to prevent material degradation. If you use custom orthotics, the factory-fitted insoles are removable to accommodate your specific arch support needs.
