Cloudboom Men's

by On

Boom.  That's the sound of another PB or record breaking.  On's Swiss engineers worked hand-in-hand with elite athletes to sculpt the ultimate marathon running shoe...  Welcome the Cloudboom!  Fitting instantly to your foot and staying comfortable over long-distances, the twin CloudTec® cushioning and a carbon-fiber-infused Speedboard® will propel you straight to the finishing line of your fastest ever marathon ever.  Boom.

On Cloudboom Features

Double level Cloudtec®

On Cloudbooms incorporate a unique double layer of Helion Superfoam CloudTec®, with one layer of Cloud elements sitting above the Speedboard™.  This upper layer of Clouds adapts to the underfoot, resulting in optimum comfort and performance.

Speedboard®: carbon-fiber-infused 

The Cloudboom Speedboard® is an explosive combination of carbon fiber and TPE materials to optimise efficiency over long distances.  The extreme rocker shape of the bottom unit translates the natural motion of the foot into propulsive power.

Traction you can rely on

The optimally redesigned traction pattern on the sole is constructed in a new grip-rubber compound which works with the natural rolling motion of the foot.  Power through wet urban courses in confidence.

Engineered mesh upper

The ultra-lightweight single layer engineered mesh upper gives the very best breathability.  Combined with reinforced side sections for additional forefoot support, your feet will thank you right through to the end of the race.
