The On Running CloudSurfer are road running shoes designed to offer exceptionally soft cushioning and a smooth transition from heel to toe. This is made possible by CloudTech Phase® technology, which uses Cloud elements in the midsole that compress in sequence, providing a smooth stride and enhanced cushioning. The Cloud elements compress one after the other as the foot strikes, providing a smooth transition and extra soft cushioning. The breathable mesh upper provides lightness and ventilation, keeping your feet cool during even the most intense running sessions. The Helion™ Superfoam midsole provides dynamic energy return, enhancing momentum during the run.
