On Cloudsurfer 2 Trainers - White/Blue - UK 11

CloudTec Phase is On's proprietary midsole technology featuring strategically placed voids that compress on impact and then expand, creating a forward-rolling sensation for a smooth transition from heel to toe.

While the cushioning is excellent for daily training and recovery, marathon runners seeking maximum energy return might prefer a more performance-oriented shoe. However, it can be a good option for marathon training or for runners who prioritize comfort on long runs.

The Cloudsurfer 2 features a new, softer Helion foam compound, providing a more luxuriously cushioned and comfortable sensation compared to previous iterations.

The shoe weighs approximately 260g (based on a men's size). This contributes to its lightweight feel during runs.

The Cloudsurfer 2 has a heel-to-toe drop of 9mm, which is a moderate offset suitable for many runners.

These trainers are primarily designed for road running and hard surfaces. The outsole is not optimized for the grip and protection required for trail running.

Refer to standard UK men's shoe sizing charts. It's always recommended to try shoes on if possible, or measure your foot length and compare it to the brand's sizing guide.

Small stones or debris might be caught in the outsole voids. Carefully inspect and clean the outsole grooves.

New running shoes often require a short break-in period. Try shorter runs initially and ensure the lacing is appropriate for your foot.

The foam is designed for durability, but its responsiveness may naturally decrease with very high mileage. Consider replacement after 300-500 miles for optimal performance.
