Nike ReactX Infinity Run 4 - Blue - UK 10

The Nike ReactX Infinity Run 4 is best suited for neutral runners looking for a daily trainer that offers excellent cushioning and responsiveness for road running, long distances, and recovery runs.

ReactX foam is designed to offer increased energy return and enhanced cushioning compared to previous ZoomX and React foams, while also being more sustainable.

Yes, the shoe's cushioning and comfort make it a great option for marathon training, particularly for long runs and easier pace days.

Clean with a soft brush to remove dirt. For tougher stains, use a mild soap and cold water with a soft cloth or brush. Always air dry away from heat.

The lifespan typically ranges from 300 to 500 miles, depending on running style, surface, and maintenance. Look for signs of wear on the outsole and midsole compression.

While the outsole offers some grip, these shoes are primarily designed for road running. They can handle light, well-maintained trails but may not provide sufficient traction or protection for technical terrain.

Loosen the laces and re-tie them, ensuring a comfortable but secure fit. If still too tight, consider a half-size larger or alternative lacing techniques.

While ReactX foam is durable, cushioning may subtly decrease with extensive mileage. Regular cleaning and proper drying can help maintain performance. Consider replacing after approximately 300-500 miles.

The outsole provides good traction but can be less effective on very wet, smooth surfaces. Exercise caution during wet runs.
