The On Men's Cloudflash Running Shoes are the fastest pair ever, refined over four years by elite athletes. Two layers of Helion™ powered CloudTec® means better cushioning and ground feeling. The Carbon-fiber-infused Speedboard™ delivers the 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. The On Men's Cloudflash Running Shoes deliver unrivaled speed and explosivity in an impossibly light design.
