Cloudboom is a lightweight, carbon-fibre-infused shoe engineered for fast marathons and road races.

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.

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’ll need for your fastest marathon ever.

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.

What our customers say: “Everything about this shoe says speed. The lightweight upper means your foot can breathe while the plated midsole delivers a superfast ride. A winner in every sense.”
