The On Running Cloudflash is the fastest On ever. It has been refined over four years by elite athletes to get you the seconds that matter most. These shoes are great for road racing, 5k, 10k, tempo training, interval training.
Built by Athletes
Two layers of Helion-powered CloudTec means better cushioning and ground feeling. The Carbon-fiber-infused Speedboard delivers our smoothest, most responsive race-day feel yet. And the new heel, created with athletes like world-champion Javi Gomez, has a lower curve and molded padding for a secure fit.
The single layer of engineered mesh is ultralight, reactive and highly breathable. No-sew support in the forefoot and metatarsal areas aid feet as they tire at the end of the race.The nonlinear lacing setup locks feet in place and a new traction pattern offers superior grip even in wet conditions.
For The Most Important Seconds in Life
The fastest On ever made even faster with feedback from elite athletes. Perfect for track work and high-speed cross-city dashes, but it's built to race. Two layers of CloudTec meet an aggressive rocker shape for unrivaled speed and explosivity in an impossibly light shoe. Let them chase.
