Minimal Running Shoe/Racing Flat/Competition



-Lightweight (Weight: 225 g | 7.9 oz. (US W 7) | 8.6 oz. (US M 8.5)

-Fits true to size

-Flexible with light and quiet impact

-Extra thin tongue, which holds foot in place without the added weight

-Use with or without socks without problems


-Oddly enough, “weight” was a pro for me with these shoes, but it’s also my first con:  Although, the Cloudracer still feels lightweight, a women’s size 7 weighs around 8.0 ounces.  Other brand’s racing shoes, such as Saucony’s Type A5 racing flat weighs in around 5.0 ounces.  Most other racing flats are around 6.0 ounces or less.  Quite a difference when it comes to the shorter, faster racing.

-User mileage.  On suggests replacing them after the mileage of 4-5 marathons, somewhere around 130 miles.  The price can be pretty steep if one intends to train and race in these shoes.


The new technology behind these shoes is the 18 rubber pods, known as clouds.  Their job is to cushion for a soft landing, then lock for a powerful takeoff, therefore reducing impact on the body.  Initially, I found the the rubber pod technology to provide some cushion during the run, but not as much as I expected.  Being that I do not like lots of cushion in my running shoes, I feel like On got it just right.  As a side note, I did notice a squeezing noise from the pods when I would run on wet roads.  This did not negatively impact the shoe’s performance.


The upper part of the shoe is made of extremely lightweight and breathable mesh.  This mesh was great at drying quickly post rainy runs.  However, due to the barely there upper, I do recommend a heavy sock or double socks when running in the colder winter temps.  I had a few runs where my toes were frozen by the end of the run.  Double layers or wool socks definitely helped.


I can be picky when it comes to trying, and actually liking new running shoes.  Fortunately, after a run or two, I realized I really liked these shoes.  Normally, I run in the Saucony Kinvara 4, and found these shoes to be comparable in width and flexibility.  It was an easy transition from the Kinvara 4 to the Cloudracers.


Overall, I found the Cloudracers to be a good running shoe.  I do prefer a lighter weight shoe for shorter races, but found the weight of these to be perfect for training, despite the shoe being tagged for competition.  The rubber pods did not make a dramatic difference in the feel of the landing for me, however the overall ride of the shoe was still a positive.  I enjoyed the lightweight design of the upper as well as the fit of the shoe.

    I honestly have never tried On running shoes, but this was a great review! I too like lighter shoes and the heaviest ones I have are about 6 oz right now. I don’t know how i would respond to a heavier shoe.
