ASICS GEL-CUMULUS 16 Trainers - Grey - Silver - UK 7

The GEL-CUMULUS 16 are designed primarily for training and everyday comfort. While they offer good cushioning, they may not provide the specialized support or responsiveness required for competitive marathon running. For marathon distances, consider shoes specifically engineered for long-distance running.

Refer to the size chart provided by ASICS and measure your foot length. The UK size for this specific listing is 7. It's recommended to try them on if possible, or ensure you understand the return policy if ordering online.

It is not recommended to machine wash these trainers. Machine washing can damage the GEL cushioning, mesh, and adhesives. Hand-wash gently with mild soap and water, and air dry.

The GEL technology in the midsole is designed to absorb shock effectively, providing cushioning and reducing stress on your feet and joints during impact.

No, the mesh upper is designed for breathability and is not waterproof. They are suitable for dry conditions and light rain but will not keep your feet dry in heavy downpours.

The lifespan varies depending on usage frequency, intensity, and surface type. For regular training and walking, they typically last between 300-500 miles or 6-12 months of moderate use before significant performance degradation occurs.
