    Well Deserved Motto, Trustworthy Race Shoe

    Since you are reading this overview, I assume that you all know what “runner’s high” mean. It's the hormonal state of the body after completing a run.

    When Swiss brand Cloudflow just before New York Marathon in 2017, they used marketing motto of “Shortcut to Runner’s High”.

    Well, after covering around 100k in different surfaces and achieving personal best in 2 half marathons within a month, I can say that the shoe deserves its marketing motto.

    It is obvious how the Cloudflow supported the World Ironman record to be broken.

     

    Fit

    I was running with Cloudflyer for over a year and I picked the exact same size with the Cloudflow.

    When I opened the box and saw the shoe, I was a little bit nervous and concerned because it has a narrower toebox than Cloudflyer. However, after putting them on, I was surprised that I did not feel what I observed.

    Cloudflow provides enough room inside even if it has a stiffer structure. It has a close and firm fit, which provides support when you would like to speed up.

     

    Outsole and Speedboard

    Cloudflow has 18 cloud pods that provide you enough cushioning.

    I believe that the different sizes of the pods have a role to provide in terms of stability since as a mild overpronator, I didn’t feel any problem at any distance; Cloudflow provides the necessary stability I was looking for.

    What makes the Cloudflow different is the speedboard that provides responsiveness and natural rolling.

    The Speedboard serves as a midsole in the Cloudflow being placed between cloud pods and insole. Built with a responsive flex and rocker, it provides flow-motion.

     

     

    Whenever you would like to speed up, Cloudflow isn’t acting as an obstacle/challenge to handle, it supports you to keep the natural running form and reach the target pace.

    While running with it, I was feeling much more explosive take-offs and it is easier to maintain my posture.

    The 6mm drop allows you to feel the ground. In general, I am running on asphalt roads and I feel more connected to the ground during my runs with Cloudflow.

    User Experience

    I have a very positive experience with Cloudflow.

    First of all, I should say that I achieved personal best time in half marathon distance twice with my Cloudflow on. I was expecting some traction control loss on wet surfaces and on rainy days and I experienced what I expected.

    I am not talking about slipping and losing balance, however, I clearly felt that some of my energy for takeoff is being lost on wet surface. I had read many negative comments on laces.

    Mainly said, laces are too thin and easily becomes untied. Contrary to that, even when I am not utilizing the second hole for tying up my laces, I did not experience any untied laces during my runs.

     

     

    At first sight, I definitely acknowledge the sleek and high-end finishing of the shoe. ON keeps paying attention to every detail and it really satisfies me on an aesthetic level.

    If you do not mind the small sized stones sticking, you can easily wear Cloudflow (or any other ON product) for daily use.

    With Cloudflow, I felt its minimal lightness (230 grams approximately) but not at the cost of losing comfort. 

     

     

    One another item I would like to mention is how ankle coverage has been designed.

    With some of my other shoes, I’m feeling like the shoe covered my ankle way too much and not providing enough mobility. However Cloudflow’s ankle coverage is pretty well, I feel the mobility room I have without feeling like the shoe can come off easily.

    I do believe that most runner would feel this detail after they take their Cloudflow for a couple of runs.

    Finally, I can say that I felt pretty proud by receiving positive comments about how “good and handsome” my shoe looks. I observe several runners having a look at my shoes at the start line, and some of them approached to ask my experience.

    The Verdict

    As final words, I am very pleased and happy to choose race shoe.

    It fits very close to my feet and the responsiveness provided with Speedboard impact is amazing!

    I was expecting some negative impact on my joints since I have mild overpronation, however never had a problem with it, not after interval training nor half marathon distances.

Updates to On Cloudflow

  • The On Cloudflow is a running shoe that’s created for those who want to have faster running outputs. Those with a natural foot-roll are the ones who are going to enjoy what this package has to offer. There are different colorways for both the men and women’s versions. They’re flashy, but not distracting to the eyes. Top-quality materials were used in this shoe.
  • The upper unit of this shoe features engineered mesh, which actually resembles woven cloth. It’s durable, supportive and it has an antimicrobial finish. Breathability is also at the top of its game because it accommodates the flow of environmental air into the foot-chamber. This model also has a built-in sock, which heightens the comfort felt by the foot. One can even wear it without putting on actual socks first.
  • The sole unit of the On Cloudflow utilizes the Zero-Gravity EVA foam, a lightweight material that’s responsive yet durable. The platform also takes a unique shape, which is visible outside the shoe: 18 semi-circular pods make up the rest of the cushioning system. Called ‘clouds’, they deliver responsible cushioning from the foot-strike to the toe-off.
  • Layered underneath the individual ‘clouds’ is a durable rubber material. It protects the foam material from the abrasive nature of the asphalt. A textured pattern ensures additional traction and surface control.

On Cloudflow size and fit

The On Cloudflow runs a bit bigger than the standard, so it is recommended for runners to choose ½ size smaller in order to get a more relaxed fit. The available width for both the men and women’s versions is medium. It accommodates those with medium sized feet.


Outsole

The outsole unit of the On Cloudflow uses the CloudTec rubber, which is a durable material that covers the cushioning ‘clouds’. It’s actually also responsive, so it adds a bit more cushioning to the runner and a bit of energy for the toe-off.

A honeycomb pattern is used in the outsole. This design is meant to improve the shoe’s grip on the surfaces, not unlike the traction patterns on a vehicle’s tire.


Midsole

Zero-Gravity EVA is the material used for the main sole unit of the On Cloudflow. It’s durable, yet it’s lightweight and responsive. It delivers reliable underfoot cushioning. It’s also the material used for the ‘cloud’ pods.
The Clouds are pods that deliver additional cushioning throughout the gait cycle. They attenuate the impact shock during the landing phase, and they push off the ground in a responsive and energized way. There are 18 of these ‘clouds’ on the surface of the sole unit.

The Speedboard is an add-on that facilitates natural foot-motion as the runner goes through the gait cycle, ending with an explosive toe-off. It also delivers torsional rigidity, which is helpful in reducing the strain and fatigue felt by the muscles of the underfoot.

A cushioned sock liner has been added to provide additional underfoot cushioning. It’s been treated with an anti-microbial coating to prevent the buildup of odor-causing bacteria.


Upper

The upper unit of the On Cloudflow features engineered mesh. It’s a breathable material that has the feel of a woven cloth. It wraps around the foot securely, but it allows the runner to move as naturally as possible.
The perforated tongue permits additional airflow into the foot-chamber. It’s thin, but it doesn’t easily fold over itself.

This running shoe has a built-in sock in its inner sleeve. It makes the interior environment more comfortable and secure. Also, it won’t allow the foot to slip around while inside the foot-chamber, thus preventing skin irritation or deviation in the running output.

The upper has been treated with an anti-microbial coating, therefore effecting a clean and healthy running experience.

A pull-loop in the heel area allows the runner to wear and remove the shoe easily.
