Nike ReactX Infinity Run 4 - Blue - UK 8.5

ReactX foam provides approximately 43% more energy return than Nike's previous React foam and significantly reduces the carbon footprint of the midsole foam, offering a more sustainable and responsive ride.

The Nike ReactX Infinity Run 4 features a redesigned upper that offers a more adaptable fit. However, if you have significantly wide feet, you may find them snug. Consider trying them on first or checking for wider fit options if available.

These shoes are designed as a versatile daily trainer, suitable for everyday runs, long-distance efforts, and recovery runs. They provide ample cushioning and support for sustained mileage.

The outsole is constructed with durable rubber designed to withstand high mileage on paved surfaces, offering consistent traction and longevity.

While the outsole offers some grip, the ReactX Infinity Run 4 is primarily engineered for road running. For trail running, it is recommended to use shoes with more aggressive traction patterns and protective features.

The release date for this model was December 13, 2023.

The engineered mesh upper is designed to stretch and conform to your foot over time. Wear them for shorter runs initially to break them in.

While the outsole offers good traction, wet surfaces can be challenging for any road running shoe. Exercise caution and reduce speed if necessary.

Ensure you are running on appropriate surfaces (roads, paved paths). Uneven wear can sometimes indicate pronation issues; consider consulting a running specialist.
