The Background Behind On’s Production of Cloudmonster: The Brand and Its History of Innovation
On is a relatively young brand founded in Zurich, Switzerland in 2010, yet it has become a notable company that has gained global support from top athletes and running enthusiasts.
The concept advocated by founder and former triathlon world champion Olivier Bernhard, together with David Allemann and Caspar Coppetti, was “running on clouds.”
The CloudTec® sole embodies this idea, and the technology that combines soft landings with powerful push-offs has been patented.
In recent years, the brand has expanded beyond running shoes, becoming increasingly active through collaborations with tennis legend Roger Federer and fashion-oriented design developments. It was within this context that the “Cloudmonster” series was born.
Featuring cloud pods with an overwhelming volume befitting the name “Monster,” along with refinements to the sole shape, this model has attracted attention for reducing fatigue during long-distance runs, intense training, and even everyday city walking.
Why Cloudmonster Is Chosen: Functionality and Design
1. Outstanding Cushioning Performance from Large Cloud Pods
The biggest feature of “Cloudmonster” is its cloud pods, which are designed to be larger than those of standard models. These oversized pods absorb impact upon landing to deliver a soft underfoot feel, while simultaneously generating excellent rebound performance.
CloudTec® is not simply soft; during toe-off, the pods return from a compressed state, using that restoring force to create propulsion. With the enlarged pods, this energy return is further enhanced, delivering truly “monster-class” performance.
2. Smooth Transitions with a Rocker-Shaped Design
The sole design of the Cloudmonster features a gently curved rocker shape across the entire sole, tailored to match the large cloud pods. This allows for smooth rolling movement when shifting weight from the heel to the forefoot.
The rocker shape is a design philosophy gaining attention in the running shoe world, helping to reduce strain on the ankles and knees and expected to lessen fatigue during long-distance running and everyday walking alike.
3. Lightweight, Highly Breathable Upper Materials
At first glance, “Cloudmonster” may appear rugged, but its upper utilizes lightweight, highly breathable mesh and synthetic materials. This design prevents heat buildup during running and maintains a comfortable internal environment for the foot.
In addition, reinforcement is applied where necessary to firmly support the foot even during long periods of activity. The extensive use of mesh materials also gives the shoe a light visual impression and serves as a design accent.
4. A Unique Silhouette and Design That Stands Out on the Street
On sneakers are generally known for their minimalist and refined aesthetic, but “Cloudmonster” lives up to its name with a sole volume that immediately catches the eye.
While maintaining its performance as a running shoe, it also features a form that looks great in street fashion, making it versatile enough for everything from casual weekend outfits to everyday city life.
Bold print designs not found on other On models add a strong accent to styling, giving the shoe a high level of visual impact on the street.
With a wide range of color variations—from understated monotones to vivid colorways—another appeal is the ability to choose according to your personal taste.
What Is the New Model Cloudmonster Void?
Cloudmonster Void is a new model redesigned from the Cloudmonster with a more comfortable design that suits an even wider range of situations.
While retaining its monster-level cushioning powered by CloudTec cushioning technology and Helion superfoam, the upper has been upgraded to a mesh inspired by functional materials to enhance breathability.
In addition, three-dimensionally molded overlays have been applied.
Featuring stylish bonded detailing and a microfiber tongue with ventilation holes, the Cloudmonster Void delivers a premium level of comfort from the moment you step in, allowing you to wear it comfortably all day long.

Comfort of Cloudmonster
The flexible cushioning of the cloud pods may feel unique at first, especially for those wearing On shoes for the first time. However, once you get used to it, many users say the soft landings and responsive push-off become addictive, making other shoes feel lacking.
In addition, thanks to the rocker-shaped sole, weight transfer to the forefoot is especially smooth. It provides comfort that helps reduce fatigue not only during long runs and walks, but also during city movement and standing work.
Cloudmonster Size & Fit Review
As with On shoes in general, some users feel that “Cloudmonster” has a slightly snug fit in terms of width. This is said to be influenced by its design, which minimizes instability as a running shoe.
Therefore, those with wider feet or higher insteps may want to consider going up about half a size. Conversely, those with standard or slightly narrow feet often find their usual size to be a good fit.
From here, we introduce actual size impressions based on staff wear tests.
If you are unsure about sizing, we hope this will serve as a helpful reference.
Female Staff Review: Usually wears 23.5cm (e.g. adidas SAMBA)
At the usual size of 23.5cm, the width felt appropriate, but the toe area felt slightly tight.
At 24cm, there was more room in the toe box, and it felt like an ideal size for sports use.
The insole features gentle contours, making it a welcome design for those with flat feet. The outsole curves toward the toe, allowing the body’s center of gravity to move forward easily, making it very comfortable to walk in.
Male Staff Review: Usually wears 26cm (e.g. adidas SAMBA)
At the usual size of 26cm, both the toe area and width felt just right. There was also room over the instep, resulting in a very comfortable fit. It felt perfect for sports use.
At 26.5cm, there was less contact between the foot and the upper around the toe area, creating more room. This size may be better suited for town use.
At 27cm, there was too much room in the toe area and it felt harder to walk, so the impression was that true-to-size or half a size up is recommended.
Is Cloudmonster True to Size or Does It Run Small?
Based on these staff reviews and feedback from customers who tried them on in-store, although individual differences apply, many people tend to choose either their true size or half a size up.
If you are unsure about sizing, we also recommend referring to the On size guide, which compares actual measurements of standard models and includes staff reviews.
Tips for Incorporating Cloudmonster into Your Fashion
Cloudmonster features a technical, unmistakably running-shoe look, but with the recent fashion trend favoring volume-sole sneakers, it blends seamlessly into a wide range of styles such as streetwear, sports-mix, and athleisure.
For example, pairing it with wide pants or long skirts to draw attention to the feet, or combining it with sporty leggings or shorts to create an active, mode-inspired style is highly recommended.
Color choice also greatly affects the overall impression. Neutral whites and grays offer a versatile look that blends easily with any outfit, while vivid colorways or accent-colored models instantly become the focal point of your coordination.
Matching colors with outerwear, bags, or hats is another technique to enhance cohesion. Not only suitable for everyday wear, Cloudmonster also delivers both comfort and style during travel and leisure activities.

Maintenance Tips for Long-Lasting Wear
“Cloudmonster” combines lightweight mesh, synthetic materials, and a rubber sole, so with proper care you can maintain both its performance and appearance for a long time.
- Removing surface dirt: After use, lightly wipe off dust and dirt with a dry cloth or soft brush. If moisture or mud is present, gently rinse with lukewarm water.
- Avoid using a washing machine: As it may damage stitching or the sole, it’s best to avoid machine washing. Hand washing followed by air drying in a well-ventilated area is ideal.
- Cleaning the sole grooves (cloud pods): Small stones and sand can easily get trapped in the deep grooves, so check regularly and remove them with a brush. This is important for maintaining cushioning performance.
- Avoid direct sunlight during storage: High temperatures, humidity, and direct sunlight can accelerate deterioration of adhesives and materials, so storing them in a breathable shoe rack or shoe box is recommended.
Conclusion: Experience Next-Level Comfort with Cloudmonster
“Cloudmonster” takes the cushioning of conventional On sneakers to the next level, paired with a distinctive silhouette. Its monster-class shock absorption and rebound from large cloud pods, smooth weight transfer enabled by the rocker shape, and the comfort of its lightweight upper make it an outstanding pair.
Not only ideal for running and training, it also has great potential for everyday city movement and fashion scenes, and its popularity is sure to continue growing.
By choosing the right size to suit your foot width and intended use, and by providing proper care, you can enjoy them comfortably for a long time. Take this opportunity to get your hands on the “On Cloudmonster” and experience a whole new dimension of comfort.
