On Cloudmonster Trainers - Black - Size 11.5

The On Cloudmonster trainers are primarily designed for road running and offer excellent comfort and energy return for daily training, long runs, and even half-marathon distances.

We recommend hand washing with cold water and mild soap. Use a soft brush to remove dirt and always air dry them away from direct heat.

The generous cushioning offers a unique blend of softness and responsiveness. While not a racing flat, many runners find the Helion superfoam provides sufficient energy return for tempo runs and even some faster efforts, though it might feel less aggressive than dedicated speed shoes.

The Cloudmonster features significantly more cushioning than most other On models, utilizing a double layer of CloudTec Phase and a substantial amount of Helion superfoam to deliver a softer, more impactful ride focused on long-distance comfort.

These trainers are optimized for road surfaces. Their outsole design and cushioning are best suited for pavement and light gravel paths, not technical trails.

The Cloudmonster generally offers a true-to-size fit. The engineered mesh upper and built-in tongue provide a secure, encompassing feel. It's always recommended to try them on or consult a sizing chart if unsure.

Ensure the shoes are clean and dry. Significant dirt buildup can affect foam performance. If the issue persists after cleaning and drying, the foam may have naturally compressed over extended use.

Verify the lacing is not too tight or too loose. Ensure you are wearing appropriate running socks. If discomfort persists, the shoe size or fit may not be suitable for your foot shape. Consider trying a different size or model.

While the rubber outsole provides good grip, wet surfaces can always reduce traction. Run with caution and be mindful of footing on slick terrain.
