On Cloudsurfer 2 Trainers - White/Blue - UK 12.5

The Cloudsurfer 2 features updated midsole foam (softer Helion foam), an improved, more breathable upper, a refined tongue design, and a new, more durable computer-generated outsole for enhanced performance and comfort.

While the Cloudsurfer 2 offers excellent cushioning for daily training and shorter to medium distances, marathon runners seeking maximum long-distance support might prefer shoes with a more robust stability system or higher stack height.

CloudTec Phase technology is designed to create a smooth and seamless transition from heel to toe, absorbing impact by collapsing voids within the midsole as you run, leading to an effortless stride.

These trainers are primarily designed for road running. The outsole is optimized for paved surfaces and may not provide adequate grip or durability on rough trails.

Refer to the sizing chart provided by the manufacturer. It's also recommended to try the shoes on, preferably later in the day when feet are slightly swollen, to ensure a comfortable fit.

The On Cloudsurfer 2 weighs approximately 260g.

Clean with a damp cloth and mild soap, then air dry away from direct heat. Avoid machine washing.

Ensure you have selected the correct size. If the issue persists, try lacing them differently or consider a different size or model.

The foam may compress slightly with use. Ensure the shoes are clean and dry, as debris can sometimes affect performance perception.

This is uncommon with the new Helion foam compound. Ensure there is no debris trapped between the sole and the upper. If the squeak persists, contact customer support.

Ensure you are using the shoes on appropriate surfaces (primarily roads). Avoid abrasive surfaces like concrete extensively or rough trails. Check for any embedded objects that could be causing excessive wear.
