Let your boys run like the clouds are cheering them on with the ON Cloudsurfer. The first-ever running shoe built specifically for kids, these shoes feature adapted CloudTec Phase technology that ensures every stride feels smooth and effortless for growing feet. Complemented by extra channels and grooves, the grippy rubber outsole stretches over the toe box for improved flexibility, so nothing slows your kids down. Light and responsive, the ON Cloudsurfer turns every run into a ride on the air. Built from the ground up for growing runners, the On Cloudsurfer Youth brings Swiss-engineered performance to grade school feet for the first time. Adapted CloudTec Phase technology makes every stride feel smooth and effortless, absorbing impact on landing and transitioning seamlessly into a responsive toe-off — so nothing slows them down, from practice laps to weekend runs. Cushioning & Road Feel On's CloudTec Phase system sits at the heart of the ride — individual cloud elements compress on impact and lock together at toe-off, delivering a cushioned landing followed by a propulsive, springy push. Paired with the lightweight Helion foam midsole and a multi-grooved outsole, the Cloudsurfer Youth keeps every run feeling airy and effortless from the first step to the final stretch.
