Product Information

Full details

The Nike ReactX Infinity Run 4 trainers are designed for adult female runners seeking a blend of high-level stability, support, and plush cushioning for their daily training sessions. By incorporating advanced ReactX foam technology, these shoes offer impressive energy return to keep your legs feeling fresh; however, users should note that the stability-focused construction may feel slightly firmer than pure plush-comfort racing shoes.

FAQs

Is this shoe suitable for trail running?

The ReactX Infinity Run 4 is specifically designed for road and smooth surface running and does not offer the lug depth required for technical trails.

How do I know if I need a stability shoe?

If you notice your ankles rolling inward (overpronation) during your run, a stability shoe like this model provides the necessary support to correct your stride.

Are these shoes true to size?

Yes, they generally follow standard Nike sizing, but it is recommended to allow for a thumb's width of space at the front of the toe box for swelling during exercise.

Can I use these for gym workouts?

While excellent for running, the stack height of the foam may feel less stable for heavy lifting. They are best reserved for cardio-based training or treadmill work.

How often should I replace these trainers?

Most runners benefit from replacing their shoes every 300 to 500 miles, depending on surface type and running form.

Troubleshooting

Feeling discomfort in the arch area

Ensure the laces are not tightened unevenly; adjust the lacing pressure to allow natural foot expansion.

Slippage inside the shoe

Check that you are using the correct size and try a 'runner's loop' lacing technique for a tighter heel lock.

Foam feels 'packed out' after heavy use

Rotate between two pairs of shoes to allow the foam cell structure to fully recover between runs.

Setup, Compatibility & Care

To ensure the longevity of your ReactX Infinity Run 4 trainers, always ensure you have the correct size for your gait cycle. When cleaning, avoid machine washing; instead, gently wipe the mesh upper with a damp cloth and mild soap. Allow the shoes to air dry away from direct heat sources, such as radiators, which can warp the foam and synthetic materials. If the insoles become saturated, remove them to dry separately.
