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.
The upper of the Cloudflash has one goal: deliver everything with nothing. Ultra-thin nano-mesh supported by a skeletal-structure work together to achieve impossible lightness.
Shaped like a race car seat, the performance heel-cap keeps your feet strapped in at high velocity. Accelerate in complete security.

When looking for a replacement for my old pair of running shoes, I came across the On Cloudflash. I could not be happier. This shoe provides a cushioned landing, explosive return, and so much stability and comfort that it makes you forget the shoe is there. I recently completed a full marathon in mine, with zero blisters, hot spots, or missing toe nails. This is a testament to the perfect fit of the shoe. Thank you On for making a shoe that far exceeds expectations of a shoe!
Bought these shoes for training for Obstacle Course Races, best running shoes I've ever had. Kept me going and made me enjoy running even more with these on my feet. These are the first running shoes I've owned that completely alleviate any pain I have in my feet while running, allowing me to run longer and harder. I even wore these to an OCR trail through mud water and 30+ obstacles and they held up better than other brands made for trail running I've owned. Won't ever buy another brand. Highly recommend.
