On worked with athletes to Swiss-engineer the ultimate shoe for marathons and road races. It’s ultralight, but powerful. It’s agile enough to handle sharp turns, but without compromise to cushioning. It’s everything you need for your fastest marathon ever. This is the sound of unstoppable. Boom.
A single layer of ultralight engineered mesh keeps weight low while increasing breathability. Reinforced sections at the forefoot hold the foot for fast cornering on the sharp turns of city courses.
Twin layers of CloudTec® in Helion™ superfoam provide both instant adaptive fit and long-distance responsive comfort.
The explosive carbon-fiber infused Speedboard increases efficiency every step and explosive kick when needed.
An updated traction pattern in a new rubber compound delivers enhanced grip.
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. Working in sync, this new CloudTec® system delivers a responsive race-day ride and protects against impact on asphalt. The upper layer of Clouds also provides an adaptive fit underfoot, so you feel the difference from the very first step.
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 – and a PR-shattering kick into the finish.
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.
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.
