Cloudboom Strike

Purpose-built for long-distance speed, the On Cloudboom Strike delivers a refined carbon-plated racing platform engineered for maximum propulsion and marathon efficiency. Its top layer of Helion HF supercritical foam creates an ultra-light underfoot feel with explosive rebound, while a drop-in Bounceboard™ layer boosts energy return to keep turnover smooth late into the race. Beneath it all, a full-length spoon-shaped carbon Speedboard® drives forceful forward motion with a seamless roll, and minimal CloudTec® elements reduce weight while supporting a clean, uninterrupted transition from stride to stride.

A translucent, single-piece race upper secures the midfoot with breathable precision, maintaining lockdown without bulk or friction during decisive pacing. Underfoot, a generous high-grip rubber outsole enhances confidence on the road, optimizing cornering and responsiveness during surges. Stripped back, propulsive, and marathon-ready, the Cloudboom Strike brings On’s sharpest carbon technology to runners aiming for personal-best breakthroughs.
