Complemented by extra channels and grooves, the grippy rubber outsole stretches over the toe box for improved flexibility, so nothing slows your kids down.

Extra grooves in the outsole improve flexibility and range of motion. 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. Breathable mesh upper delivers all-day comfort, airflow, and a supportive fit for active kids. Adapted CloudTec Phase midsole cushions impact and promotes a natural, smooth gait tuned specifically for growing feet. Helion foam core keeps the midsole lightweight and resilient mile after mile. Grippy rubber outsole extends over the toe box for enhanced flexibility and confident push-off. Extra channels and grooves throughout the outsole improve range of motion and adapt to varied surfaces. 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.
