Description

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.
