Nike ReactX Infinity Run 4 - White - UK 10.5

ReactX foam is Nike's latest cushioning innovation, designed to provide a softer feel, improved energy return, and a reduced environmental footprint compared to previous foams.

Yes, the ReactX Infinity Run 4 is designed with ample cushioning and support, making it suitable for long-distance running, including marathons.

Refer to Nike's official size guide for accurate measurements. This model is designed for adult male runners, and the UK 10.5 size is specified.

While they offer good support, they are primarily optimized for running. For dedicated cross-training, shoes with more lateral stability might be preferable.

Generally, running shoes should be replaced every 300-500 miles, or when you notice significant wear on the outsole or a reduction in cushioning.

The primary difference is the introduction of ReactX foam in the midsole, offering enhanced sustainability, softer cushioning, and better energy return.

Allow for a break-in period of 10-15 miles. Wear them for shorter runs first to let them mold to your feet. Ensure laces are not overtightened.

Ensure the shoes are clean and free of debris. Check if the ReactX foam has been exposed to extreme temperatures, which could affect its properties. Proper care as outlined above will help maintain cushioning.

While the outsole offers good traction, extremely slick surfaces can still pose a risk. Run with caution on wet or icy conditions. Ensure the outsole is clean of mud or debris.
