Brand:On Running

Code:37.99641 M

Hear that? That’s the sound of your PR falling and records breaking. Of Swiss engineering colliding with elite athlete input to create the ultimate marathon shoe. Introducing the Cloudboom. Engineered with twin CloudTec® cushioning for instant fit and long-distance comfort. Featuring a carbon-fiber-infused Speedboard™ to kick right through the 42.2/26.2. Everything you need for your fastest marathon ever. Boom.

A higher level of Cloudtec®
The Cloudboom incorporates a layer of Cloud elements above the Speedboard™ for the first time, creating a unique new twin layer of CloudTec® in Helion superfoam. The upper layer of Clouds also provides an adaptive fit underfoot.

New carbon-fiber-infused Speedboard®
Engineered for efficiency over long distances, the Cloudboom Speedboard® is made from an explosive combination of carbon fiber and TPE. The extreme rocker shape of the bottom unit optimizes the rolling motion for even more propulsive power.

Optimized traction
A new grip-rubber compound in an advanced traction pattern is designed according to the natural rolling motion of the foot. The result? A firm hold as you crush wet city courses at speed.

Engineered mesh upper
The single layer of engineered mesh ensures low weight and maximum breathability. Reinforced sections provide additional forefoot support as feet tire toward the end of the race.
