The lightweight, carbon-fiber-infused shoe engineered for fast marathons and road races.
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.
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.
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.
