On Cloudmonster 3 Trainers - Black - UK 9.5

Yes, the exceptional cushioning and responsive nature of the Cloudmonster 3 make them highly suitable for marathon distances, providing comfort and energy return over many miles.

While their design is optimized for running, the supportive nature and comfort make them acceptable for light gym activities. However, for activities requiring lateral stability, dedicated cross-training shoes are recommended.

You should have about a thumb's width of space between your longest toe and the end of the shoe. The heel should feel secure without slipping, and the midfoot should feel comfortably snug, not constricting.

The Cloudmonster 3 typically features updated cushioning compounds and outsole designs for enhanced performance, comfort, and durability compared to earlier versions.

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

No, the On Cloudmonster 3 are not waterproof. They are designed with breathable materials for ventilation, which means they will not keep your feet dry in wet conditions.

Ensure you have selected the correct size. Try loosening the laces and re-lacing them for a more customized fit. Consider using the extra eyelets for a heel lock if needed.

Cushioning technology can feel different as it adapts to your foot. If cushioning truly diminishes, ensure the shoes are not excessively worn or damaged. For significant loss of performance, consider replacement.

The outsole is designed for road grip. For significantly wet or slippery conditions, proceed with caution. Clean the outsole periodically to ensure optimal traction.
