On Cloudboom - Sandstorm/Eclipse

The On Cloudboom is designed to be the ultimate Marathon running shoe – built with input from elite athletes to be suitable for 40km road races and long-distance interval running, while also ensuring comfort, this shoe brings Swiss engineering and innovation to the fore. The layers of Cloudtec cushioning in the On Cloudboom use a series of pods or clouds that collapse under the impact section of your stride, but then become a solid base to push off from in the later stage. This provides a soft cushioned feel (like running on clouds) in the early stage, that transforms for explosive take offs later. This Helion Superfoam ensures a comfortable and adaptive fit, keeping you on your feet and kicking through the Carbon Fiber-infused Speedboard for responsive performance, with updated traction pattern for enhanced grip. Above the sole, a single-layer ultralight engineered mesh material provides high breathability and low weight, with a reinforced forefoot that holds you in place on tights corners.
