This model weighs 295g (for a UK 9.5). This weight balances its maximal cushioning and performance features.

The On Cloudmonster 2 is specifically engineered for road running. Its outsole pattern and maximal cushioning are best suited for paved surfaces. For technical trails or uneven terrain, a dedicated trail running or hiking shoe would provide better grip and stability.

Ensure you are wearing appropriate running socks. Adjust your lacing technique; try different patterns to relieve pressure points. Allow for a break-in period of a few runs if the shoes are new. If discomfort persists, check your size.

Running shoe midsoles degrade over time with mileage. Most running shoes have a lifespan of 300-500 miles (500-800 km). If you've surpassed this range, it's likely time to consider replacing your shoes as the cushioning has compressed beyond recovery.

A squeak can often be caused by the insole rubbing against the shoe's footbed, especially if it's damp. Try removing the insole, cleaning both surfaces, ensuring they are dry, and reinserting it. If the issue persists, a new insole might be needed, or it could be a structural component that requires inspection.

Ensure you are using a secure knot, such as a double knot or surgeon's knot. The new eyestays are designed for enhanced lockdown, so proper lacing tension is key. You can also consider replacing the laces with ones that have more grip.
