The lightweight, carbon-fiber-infused shoe engineered for fast marathons and road races.
Sustainability
We’re constantly working on reducing the global footprint of all our products. In the near future, sustainability information will be available for this product too.
Technology
Powered by Carbon The Cloudboom features a new carbon-fiber-infused Speedboard™ for serious explosivity and speed. And for the first time ever, we created a twin layer of CloudTec® in Helion superfoam. One above the Speedboard™ and one below, delivering a unique, adaptive fit underfoot.
Materials
Optimized for Agility A single layer of ultralight engineered mesh keeps weight and temperature down. Reinforced sections at the forefoot add the stability needed to handle sharp turns on asphalt. Team this with a new traction pattern on the sole and you’re ready to crush city courses, even in wet conditions.
Design
The Sound of Unstoppable We 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.
Best For
Fast marathons, Road races between 10 – 42.2km, long-distance intervals
