On Cloudultra Pro

Built to go further, faster, the On Cloudultra Pro is engineered for runners tackling ultra-distance trails where efficiency matters as much as speed.
Developed alongside elite athletes and proven at some of the toughest multi-day mountain races in the Alps, it is designed to conserve energy over long distances without sacrificing responsiveness. A dual-layer Helion™ HF hyperfoam midsole works with a Speedboard® rebound system to deliver a highly efficient blend of cushioning, propulsion and stability, helping you maintain rhythm across climbs, descents and technical terrain.

Up top, a zoned Leno weave upper provides lightweight breathability, quick-drying performance and secure support where it is needed most. Underfoot, the latest Missiongrip™ outsole features an advanced lug pattern developed using Finite Element Analysis (FEA), delivering exceptional grip and traction across varied mountain terrain.
