On Running Cloud X 3 AD - Black - UK 7

The Cloud X 3 AD is designed for versatility and shorter to medium-distance runs. For marathon distances, athletes may prefer a shoe with more specialized long-distance cushioning and support.

Ensure there is a thumb's width of space between your longest toe and the front of the shoe. The heel should feel secure without slipping, and the midfoot should be snug but not constricting.

The mesh upper offers breathability but is not waterproof. While they can handle light moisture, they are not ideal for prolonged exposure to heavy rain or wet conditions.

The Cloud X 3 AD is specifically engineered as an ultra-light, highly reactive trainer for a broad range of activities. Other ON Running models might focus more on maximum cushioning, stability, or specific running disciplines like trail running.

This depends on usage frequency and intensity. For regular runners, it's generally recommended to replace trainers every 300-500 miles, or when you notice significant wear on the outsole or a loss of cushioning.

Typically, the insoles in ON Running trainers are designed to be removable, allowing space for custom orthotics or preferred insoles. Check the specific product details or try carefully removing them.

Adjust the lacing system. Ensure you are using the correct UK size. For persistent discomfort, consider wearing them for shorter periods initially to allow them to break in.

Over time, cushioning can naturally degrade. Ensure the shoes are clean and free of debris. If performance significantly declines, it may be time to consider replacing them, especially if used frequently.

Be mindful of abrasive surfaces during activities. Clean gently with a damp cloth and avoid harsh scrubbing.
