Nike ReactX Infinity Run 4 - Trainers - UK 11 - White

Measure your foot length from the heel's most prominent point to the tip of your longest toe. If your measurement falls between two sizes, it is recommended to choose the larger size for optimal comfort.

While they offer excellent cushioning and support for training, they are designed more for comfort and durability on daily runs rather than for competitive racing where lighter, more minimalist shoes are often preferred.

It is generally recommended to replace running shoes every 300-500 miles (480-800 km) or when you notice a significant decrease in cushioning and support, or signs of wear on the outsole.

No, machine washing is not recommended as it can damage the materials and construction of the shoe. Hand wash using mild soap and cool water.

The ReactX foam provides enhanced energy return and a softer, more responsive cushioning experience compared to previous Nike foam technologies, leading to improved comfort and reduced fatigue during runs.

No, the upper is made of breathable mesh materials designed for ventilation, not waterproofing. They are suitable for dry conditions and light moisture but not for heavy rain.

Ensure you have measured your foot accurately according to the sizing guide. If between sizes, choose the larger one. Consider trying on different sizes if possible.

The cushioning may naturally compress after extensive use. Ensure the shoes are clean and the midsole is free of debris. For significant degradation, replacement may be necessary.

While designed for good traction, grip on very wet surfaces can be reduced. Clean the outsole regularly to remove any embedded debris. For very slick conditions, consider specialized footwear.

Check sock type and thickness, ensure laces are tied correctly to provide a secure but not overly tight fit, and confirm correct sizing. Break-in periods may be required for new shoes.
