Stylish, lightweight and cushioned, the On Cloudsurfer gives you a smooth ride to roll through the miles. This shoe is a complete reboot of the On Cloudsurfer. New CloudTecreg Phase midsole technology gives you active cushioning that compresses and springs you forward. It collapses in a domino-like sequence to deliver cushion and a gentle heel-to-toe transition. On uses a midsole that consists of a Heliontrade Superfoam in an entirely new construction based on computer-optimized FEA engineering. Designers then eliminated the Speedboardreg present in many of their other shoes to make the Cloudsurfer lighter, give you a more cushioned feel and reduce the chance of catching stones during your run. In our On Cloudsurfer review, one runner stated, ldquoAfter the first mile, I could confidently say that the Cloudsurfer is the softest pair of On running shoes Irsquove ever run in.rdquo Super lightweight, this shoe can be used for walking, running and speedwork. Plus, lightweight rubber pads on the outsole give you durable traction in all conditions. The upper gives you a plush step-in feel with a breathable engineered mesh. On continues their efforts to make their shoes more sustainable by eliminating plastic overlays, while 30 of the shoe is made from recycled materials and uses dope dye technology that saves significant water in the dying process. Feel like you are running on clouds in the On Cloudsurfer.
