FAQs

Is this shoe suitable for trail running?

These are primarily designed for road and paved surfaces. They lack the aggressive lugs necessary for technical trail running.

How should I clean the white upper?

Gently wipe with a microfiber cloth dipped in mild soapy water and let them air dry.

Can I replace the insoles?

Yes, the insoles are removable if you prefer to use custom orthotics.

Are these shoes true to size?

Most users find them to be true to standard Nike sizing, though those with wider feet may prefer a half-size larger.

How long will the ReactX foam last?

Depending on surface and running style, the foam typically maintains its responsiveness for 300 to 500 miles.

Troubleshooting

Feeling of slippage inside the shoe

Re-lace the shoes using a runner's loop (heel lock) method to secure the ankle.

Foam appearing compressed after use

ReactX foam requires time to recover; allow 24 hours between runs for the material to decompress.

Setup, Compatibility & Care

To ensure the longest lifespan for your Nike ReactX Infinity Run 4, proper care is essential. When fitting, ensure you have approximately a thumb's width of space at the front of the shoe to accommodate natural foot swelling during exercise. For cleaning, remove loose dirt with a soft brush and use a damp cloth with mild soap; avoid machine washing as this can damage the foam and adhesive. Always air dry in a cool, shaded area away from direct sunlight or heat sources to prevent the materials from warping or degrading.
