On Cloudboom: Booming into a new milestone

The On Cloudboom may be considered as a special shoe of sorts. It is the first model from the brand to use a carbon fiber plate in the midsole. Thus, if you are after increased propulsion or improved efficiency, this shoe is worth looking into.

Who is it for? The On Cloudboom is designed for neutral pronators. Its 9mm drop might be most appealing to midfoot strikers, but definitely okay to use no matter your running form.

What is it for? The Cloudboom is meant for city surfaces. You can use them for marathons or even short races on the road. If not for competitions, the Cloudboom will also do well in fast-paced workout runs.

Fast facts of the On Cloudboom

  • From the get-go, the On Cloudboom aims to be set apart from its counterparts. Unlike the usual racing shoe, the Cloudboom has a higher drop and a lower stack height. This results in moderate cushioning and ample ground feel, thus bringing a novel running sensation.
  • Other racing shoes, like the Nike Alphafly Next%, employ a cushioned sole. The Cloudboom offers a firmer platform. Such a quality promotes a snappy ride. Not to mention, a robust form and a more durable structure.
