On Running CLOUDMONSTER Void Trainers - Green - UK 4

Yes, the maximum cushioning and energy return make them an excellent choice for marathon training and racing, especially for runners who prioritize comfort and joint protection over maximal speed.

These trainers are primarily designed for road running. While they might handle very light, well-groomed gravel paths, they lack the aggressive traction and protection needed for technical or muddy trails.

The rocker design promotes a forward-rolling motion, which can feel very natural and efficient. If you experience discomfort, it might mean your natural stride doesn't align well with this type of geometry, or a break-in period is needed.

The Cloudmonster features On's most substantial CloudTec® cushioning and a pronounced rocker compared to many other On models, prioritizing maximum comfort and energy return for longer runs and road surfaces.

Running shoe mileage varies, but typically, trainers like the Cloudmonster should be replaced after 300-500 miles (500-800 kilometers) of use, or when you notice significant wear on the outsole or a loss of cushioning responsiveness.

Color representation can vary slightly based on screen settings and lighting. The 'Green' variant offers a distinct shade intended for visibility and style.

The shoes often require a short break-in period. Wear them for shorter runs or walks initially to allow the cushioning and materials to adapt to your feet.

Ensure the laces are tied securely using a double knot. Consider replacing the laces with a pair that has better grip if the issue persists.

The outsole provides good traction on dry roads. For wet conditions, exercise caution as with any running shoe. Ensure the outsole is free from debris.

This could be due to the shoe's specific support geometry or your foot's natural arch. Try adjusting the lacing or consider using an aftermarket insole with a different arch profile.
