Nike ReactX Infinity Run 4 - Trainers - UK 7

The ReactX foam offers enhanced cushioning and improved energy return compared to previous Nike React foam, providing a more responsive and comfortable ride with reduced environmental impact.

These trainers are primarily designed for road running. While the outsole offers durable traction, they are not specifically built for the demands of technical trail running.

The trainers should feel snug but not tight. Ensure there is adequate room in the toe box, and your heel does not slip. Refer to Nike's sizing guide for accurate measurements.

No, machine washing is not recommended as it can damage the materials and construction. Hand clean with a damp cloth and mild soap, then air dry.

The lifespan varies depending on usage frequency, running surface, and individual gait. Generally, running shoes are recommended to be replaced every 300-500 miles or when signs of significant wear appear on the midsole or outsole.

This specific product guide focuses on the 'Triple White' colorway. Other color options may be available through different product listings or retailers.

Colors may differ slightly due to variations in lighting, environment, and screen settings during photography and viewing.

New shoes, especially with advanced foam technology, may require a few runs to fully conform to your foot shape. Wear them for shorter distances initially to allow them to break in.

Ensure the correct UK size has been selected. The secure lacing system can be adjusted to fine-tune the fit. Consider trying different lacing techniques if needed.
