On Running Cloudflash Women's


Cushioned landing, explosive take-off

The 14 Cloud elements below the Cloudflash are shaped to transform and transfer more impact energy from the runner into fast, forward momentum.


The Cloudflash Speedboard, built from Pebax, is unparalleled in energy transition and fatigue resistance. It loads with impact energy to change toe-off to take-off at release.

Secure fit

Shaped like a race car seat, the performance heel-cap keeps your feet strapped in at high velocity. Accelerate in complete security.
