83 / 100 based on 5 expert reviews

  • 88 / 100 by Sota Sato • Sota Sato • Level 1 expert

    Insane shoe, made for high performance athletes.

  • 78 / 100 by Gearist • Brandon Wood • 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 by Runner's World • 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 by Men's Health • 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 by Men's Health • 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.

Updates to On Cloudracer 2

  • On made very slight changes to the Cloudracer 2 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 Cloudracer 2 size and fit

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.


Outsole

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.


Midsole

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.


Upper

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.
