Nike React Infinity Run 4 - Trainers - UK 9.5

Measure your foot length from heel to toe. If your measurement falls between two sizes, we recommend choosing the larger size.

While they offer good responsiveness, they are primarily designed as daily trainers for consistent comfort and support rather than for pure speed racing.

No, the Nike React Infinity Run 4 is designed for road running and general training. The outsole may not provide adequate grip or durability for trail surfaces.

Generally, running shoes should be replaced every 300-500 miles (480-800 km) or when you notice significant wear on the outsole or a loss of cushioning.

The React Infinity Run 4 features the new ReactX foam, which offers improved energy return and reduced environmental impact compared to previous React foams.

Yes, they can be used for general gym workouts, but they are optimized for running. For activities requiring significant lateral stability, like weightlifting, dedicated training shoes might be more suitable.

Use a soft brush or cloth with a mild soap and water solution to gently clean the engineered mesh. Avoid harsh chemicals.

Try loosening the laces and re-tying them, ensuring they are not overtightened. If the snug fit persists after trying them on indoors, consider exchanging for a half-size larger, especially if your foot length is between sizes.

Ensure you have the correct size. The ReactX foam is designed for a balanced feel; if you require maximum plushness, this model might offer less than some specialized maximalist shoes. Consistent use may also break in the foam further.

The rubber outsole provides good traction, but wet surfaces can be inherently slippery. Exercise caution in wet conditions. Ensure the outsole is free of debris that might impede grip.
