83 / 100 based on 5 expert reviews

  • 88 / 100 | Sota Sato | Level 1 expert

    Insane shoe, made for high performance athletes.

  • 78 / 100 | Gearist | | Level 5 expert

    The closer to the ground feel and construction gives excellent ground feel and the response, thanks again to the stiff strobel board/Speedboard construction is very good.

  • 70 / 100 | Runner's World | Level 5 expert

    It's not pillowy soft, but you wouldn't expect it to be, given that you're only an inch from paved surfaces.

  • 93 / 100 | Men's Health | Level 4 expert

    Like its predecessor, the Cloudracer 2’s impressive mix of cushioning, stability and swiftness is hard to beat.

  • 93 / 100 | Men's Health | Level 4 expert

    This very impressive performer may have been built primarily for your PB-busting efforts at road races and triathlons – Ironman competition even.

  • On made very slight changes to the Cloudracer in order to maintain the top quality and performance of the original model. The biggest change in the 2nd version of the Cloudracer is the Speedboard in the midsole. This greatly influences the stability and responsiveness of the shoe.
  • Another notable change that will certainly boost the shoe’s performance is the removal of basically all stitching. What makes this change even more significant is the fact that the mesh upper is incredibly very light, flexible, and softer now. Without the stitching, there should be very little risk of getting an irritation or rubbing.

On made sure to retain the fit and sizing of the original model, which are on the dot. Runners with average foot will find the medium heel and midfoot fit superb. However, as with most racers, the forefoot is a bit snug so sizing up is always an option for those who want more wiggle room in the toe box. Available widths are D and B while sizes are from 7 to 15 for the men’s and 4 to 13 for the women’s.


The outsole makes up a large portion of the shoe as the On’s patented Cloudtec technology is found here. Cloudtec is made up of 13 pods, 9 in the forefoot and 4 in the heel, that compress upon landing and lock themselves together for enhanced propulsion and traction. The Clouds also basically serve as the shoe’s cushioning system. Beneath the clouds is a honeycomb pattern of rubber for traction and durability. This CloudTec technology is also used in the On Cloud running shoes and other running shoes from ON Running.


A high-grade EVA is located in the midsole for cushioning properties as well. The main feature, however, is the new Speedboard. This technology uses a plastic material built with rails that are specifically designed for the forefoot, the midfoot, and the heel for respectable stability and decent smoothness through the gait cycle.


An Ultra Light Airmesh offers unbelievable breathability. It is so porous that runners can literally see their feet through the mesh. As the mesh is now softer, it also feels very comfortable to the skin for a really nice wrap on the foot. A Super Light perforated tongue keeps up with the pace of the mesh regarding ventilation. On includes a reflective material on the TPU heel counter while a non-slip lining is part of the nice fit.
