On Running Cloudmonster - Black - UK 12

While the Cloudmonster Void offers exceptional cushioning for comfort, it is primarily designed for casual jogs and daily active wear. For serious marathon training or competitive racing, you might find more specialized On Running models that are engineered for higher mileage and race-day performance.

We recommend measuring your foot length and width, then consulting the official On Running size chart. For running shoes, it's often advised to go up half a size from your regular shoe size to accommodate for foot swelling during activity and to ensure enough toe room.

Yes, the comfortable and supportive design of the Cloudmonster Void makes them suitable for general gym activities, including cardio machines (like treadmills and ellipticals) and light weight training. However, for highly specialized training requiring maximum stability or ground feel, other shoe types might be more appropriate.

The rubber outsole is designed to provide steady grip and traction primarily on paved surfaces such as roads, sidewalks, and well-maintained paths. They are not recommended for rugged off-road trails or highly technical terrains, where specialized trail running shoes would perform better.

To clean the mesh upper, first gently brush off any loose dirt with a soft brush or dry cloth. For deeper cleaning, dampen a cloth with cool water and a small amount of mild soap, then carefully wipe the affected areas. Avoid scrubbing aggressively. Always allow the shoes to air dry completely afterwards.

CloudTec® is On Running's signature cushioning system, featuring individual 'cloud' elements on the sole. These elements compress horizontally and vertically upon impact, providing soft landings and absorbing shock. They then lock firm for a powerful and explosive push-off, creating a unique 'running on clouds' sensation.

The Speedboard® is a liquid-injected plate integrated into the midsole. Its purpose is to stabilize the foot, distribute pressure, and act as a spring, providing a propulsive feeling that aids in a smooth transition from landing to push-off, enhancing the shoe's responsive feel.

Re-evaluate your lacing. Ensure even tension across the entire foot. You might try different lacing techniques to customize the fit, such as skip-lacing for pressure points or heel-lock lacing for slippage. Also, confirm you are wearing appropriate athletic socks.

Check if the insoles are correctly seated. Remove them, clean any debris or moisture from underneath, and reinsert them firmly. Sometimes, new shoes might produce a temporary squeak due to friction between materials, which often resolves after a few wears. If it persists, ensure no moisture is trapped inside the shoe.

Running shoes have a finite lifespan, typically ranging from 300 to 500 miles, after which the cushioning material begins to degrade. If your shoes have accumulated significant mileage or if you notice persistent discomfort or lack of responsiveness, it may be time to replace them. Proper storage away from extreme conditions can also help preserve cushioning.
