Nike React Pegasus Trail 4 GTX - Pale Ivory/Bright Mandarin-SAIL-JAD - UK 5

Nike React is a responsive foam cushioning that provides a soft yet energetic feel, designed to absorb impact and return energy with each stride.

While they can be used on roads, their primary design and tread pattern are optimized for trail surfaces. For dedicated road running, a road-specific Pegasus model might be more suitable.

The UK size 5 is a specific measurement. Ensure there is a thumb's width of space between your longest toe and the end of the shoe. The shoe should feel snug but not tight, with no heel slippage.

The rubber tread is designed for durability on trail conditions, offering good wear resistance. However, aggressive use on abrasive surfaces can still lead to wear over time.

It is not recommended to machine wash these shoes, as it can damage the materials and the GORE-TEX membrane. Hand washing with mild soap and water is the preferred method.

GTX stands for GORE-TEX, a brand of waterproof and breathable membrane used in the shoe's construction to keep your feet dry from external moisture while allowing sweat vapor to escape.

Ensure laces are tied properly and the tongue is fully engaged to prevent water ingress. Check for any damage to the GORE-TEX membrane. Allow shoes to dry completely after wet use.

The rubber tread is designed for trails. For extremely slick surfaces like polished concrete when wet, grip may be reduced. Clean any mud or debris from the outsole tread for optimal performance.

Ensure the correct UK size is being worn. Try wearing different types of running socks. Break in the shoes with shorter runs before attempting long distances.
