Our verdict

The On Cloudflyer is a mild stability shoe best used for steady runs in wet weather. My feet remained dry on the runs accompanied by rain and the grip never failed me. However, I do believe that ON has a long way to go before coming anywhere close to being a competitor in the rapidly evolving market of shoe technology.

Audience verdict


A foreword about On

Consumers are intrigued with the brand's unique method of providing cushioning: multiple holes in a segmented midsole known as 'Cloudtec' and 'Zero Gravity Foam' which compress upon impact.

Consumers are further bought over thanks to the clever wordplay utilized in marketing the shoes. A great example would be the Cloudflyer. Bombastic words such as 'supreme cushioning' and 'running on clouds' are coupled with a premium price point and 'swiss engineering.' One would immediately think of a shoe that is as soft as a marshmallow and of excellent construction. 

Before delving into the review, here’s some of my background. For the past 6 months, I’ve worked in a sports shop specialized in running shoes and gear. This shop carries brands such as New Balance, ASICS, Saucony, and Hoka but places great emphasis on ON running shoes.

As a result, ON shoes are the best-selling brand in the store. Working in a store like this has allowed me to test and compare ON shoes fairly with the offerings of other brands and how ON stacks up against the rest of the market.

Upper of the Cloudflyer Waterproof

Waterproof and breathable

The Cloudflyer Waterproof uses a fully waterproof yet breathable engineered mesh that keeps both wind and water out of the shoe. There are also reflective elements in many parts of the upper material which allows for safer running at night or in heavy rain.

The waterproof layer is surprisingly breathable. I expected a hot shoe especially at 32°C weather, but the shoe remained decently cool even at such conditions. The waterproof layer serves it’s purpose well.

I ran about 5-6 runs in moderate rain, and I’m pleased that my feet were kept dry. The only area that got wet was near the ankle collar, which did not really bother me. Also, the reflective elements are good looking and work very well for me at low light conditions.

The ankle collar is cushioned well and irritation free

The padding at the sides reminds me of a car seat. It hugs the ankle nicely and provides great comfort to my ankle.

However, the padding on the medial side of the shoe should be done away with. With reference to the picture below, the padding makes the shoe look less aerodynamic and more out of shape. It ruins the look from an aesthetic point of view but does not affect the performance of the shoe.

The heel counter is a great contributor to the stability of the shoe. The Cloudflyer comes with a substantial heel counter which cradles the foot and keeps it from shifting around in the shoe.

No lacing pressure

In the Cloudflyer, the tongue is well cushioned. It protected the top of my feet well from any lacing pressure.

An important thing to note is the tongue is fixed to the shoe. This means that consumers would not have to worry about the tongue shifting all over the place.

The Cloudflyer runs on the narrow side

I had to change the special 'star lacing' at the front of the shoe to accommodate and allow my feet to spread.

The star lacing at the front was intended by ON to provide more stability and a better fit for the user. However, for people with wide feet, this lacing technique just cramps up the toe box further.

Changing the lacing did not result in any noticeable loss of support or comfort for me. Even with the laces changed, the shoes continue to squeeze my foot mildly but not to the extent of discomfort.

Midsole & ride quality


The Midsole is made of EVA foam molded into unique 'CloudTec' pods. The pods collapse upon impact, softening the landing of the runner. The compressed pods would then provide a firm platform for the take-off.


I’m not sure what makes the ride of the shoe uninspiring - the type of foam used or the concept behind the midsole technology. I find the ride rather dull and unresponsive. I don’t get any softness from the shoe, everything is just firm.

At recovery places, the shoe felt too harsh. At paces up-tempo and above, the weight and the unresponsive feel made it unenjoyable to run in. Running on the treadmill or at steady paces are quite smooth.

The shoe is definitely stable, to the point that it feels clunky sometimes. With the cushioning setup, this shoe will be a great crossfit shoe for gymming and the occasional run on the treadmill.


The Speedboard is made from a semi-flexible plastic that provides smoother heel-to-toe transitions and increased stability overall. I found the Speedboard to work especially well on treadmill runs.

The Speedboard definitely balances out the pods evenly and make them work as a cohesive unit. This prevents uneven pressure to be applied to individual pods.

A drawback of the Speedboard is that it firms up the shoe significantly. ON tends to place the Speedboard so close to the foot as it’s impossible for the Speedboard to be positioned anywhere else due to the design of the midsole.

Having the Speedboard this close to the foot results in a ride that is far from plush. Think of it as lying down on a wooden plank on a pillow compared to a pillow on a wooden plank.

The description of the latter would definitely be more comfortable. ON has made an effort to soften the ride through the use of a special insole, which will be addressed below.


The insole is made up of two sections. The first section is a green memory-like foam that compresses easily. It is soft but does not have good rebound properties. The insole shines at walking paces but fails to impress when paces are picked up.

The second section is a black foam material that starts from the middle covering and cupping the first section at the heel. The intended purpose is to center the heel on the green platform. The function seems to work decently well as I don’t find my heel slipping around.

I remember in my first ON shoe review on the ON Cloud that I hoped for a different insole material to make for a more forgiving ride. ON did change the material to the current memory foam variant. However, I’m not sure if this was a step in the right direction for ON as the foam does not return to its original form fast enough to cushion the next few steps while running.

I really do hope ON reads this and starts to consider thermoplastic-polyurethane for its insole foam or adding a thin layer below the insole. Having a Speedboard in a shoe is fine, but having it so close to the foot means that the ride will be more firm in nature. Utilizing a soft yet responsive material in between the foot and the board would dilute some of the firm characteristics and allow more forgiving and enjoyable ride at slower paces.



The Outsole is strategically placed with black rubber patches at high wear areas in both the forefoot and heel for added durability and grip.


The outsole is pretty grippy in dry conditions and decent in wet conditions. I did not slip in wet weather when running on asphalt. I wonder if the outsole compound is an improvement from that of the non-waterproof version which lacked a lot of wet weather grip.



The midsole is holding up well with 80km (50mi) in. However, I worry that with this combination of EVA material and individual segmented holes in the cushioning, the pods are bound to collapse sooner than if the midsole was one-piece.


The outsole shows little signs of wear on the black rubber pieces that cover most of the shoe. The tread of the 3 segments that are not covered is holding up better than I expected.


ON Cloudflyer Waterproof vs. Nike Odyssey React Shield

Two mild stability shoes with waterproofing technology. Both companies technology works effectively, keeping water out during wet weather.

The Cloudflyer is slightly more breathable which makes it more suitable for hot and humid weather. The Odyssey weighs 43 grams lighter and runs softer than the Cloudflyer. Both shoes fit on the narrow side.

Choosing between these shoes will be a matter of preference. One thing to note is that the Odyssey is cheaper than the Cloudflyer by a significant amount.

ON Cloudflyer Waterproof vs. Nike Pegasus Turbo

The Pegasus Turbo is one of the best versatile trainers in the market right now. The Cloudflyer Waterproof is 54 grams heavier than the Turbo and offers a much firmer ride despite being marketed as 'supremely cushioned.'

The Turbo is much softer and responsive, performing well for recovery runs to track intervals. Other than the added stability and waterproofing on the Cloudflyer, the Turbo is just on a different level.
