On - Cloudflow 5 Lumos Glacier / Black Running Shoes

The men’s On Running Cloudflow 5 Lumos running shoes in Glacier and Black are engineered for fast, forward-rolling runs with advanced cushioning and responsive propulsion.

At the core is a layer of Helion™ HF superfoam, a Swiss-engineered technology that fuses stability and flexibility for unmatched energy return, delivering a soft yet springy ride that powers your stride. This foam is complemented by a propulsive nylon-blend Speedboard® reinforced with glass fibers, storing and releasing energy to accelerate toe-off, while the rockered geometry of the midsole ensures a fluid, fast transition with each step.

The engineered woven mesh upper offers breathability and ultralight comfort inspired by On’s pinnacle race-day shoes. Reflective elements enhance visibility for safety during low-light conditions, and the updated toebox design allows for targeted support during high-speed training sessions.

Forefoot grip rubber enhances traction for confident toe-off and quick directional changes, making the On Running Cloudflow 5 Lumos Glacier and Black Running Shoes are ideal for tempo runs, intervals, and race-day performance.
