Initial Impressions and Design
One of the first things to note about the On Cloudmonster 2 is its distinct look. The shoe adopts On’s signature Swiss cheese-like style but takes it to the extreme. From a distance of about 25 meters, you won’t mistake these for anything else. Besides the eye-catching design, the shoe comes in some appealing colorways. The all-white variation, for instance, is notably clean and modern. Looks aside, stepping into the shoe for the first time feels pretty good and comfortable.
The Upper: Style vs. Functionality
The upper of the Cloudmonster 2 is a point of contention. While it’s comfortable, having ample padding around the heel, it’s a bit too spacious in the toe box. The upper mesh material fails to provide the structured support needed to get a secure fit. This bagginess in the toe area can be especially problematic if you have narrower feet. Some people might find themselves needing to size down considerably to avoid swimming in their shoes.



Midsole Magic
The heart of the Cloudmonster 2 lies in its midsole. Sporting a dual-density Helion midsole and the largest-ever CloudTec pods, the shoe offers a firm yet cushioned ride. The Speedboard is nested between the two layers, contributing to a unique rocker sensation when running. It’s a firm ride for a max-cushion shoe, which may take some getting used to, but it delivers exceptional stability and protection. The dual-density foam adds a bit of extra push during toe-off, making each stride feel just a bit more powerful.


Outsole and Durability
The outsole of the Cloudmonster 2 is as distinct as the rest of the shoe. The large CloudTec pods act like mini tank treads, providing grip and impact absorption. The resilience of the outsole material suggests good durability, and we expect it to stand up well to regular use. However, don’t expect nimbleness from this shoe; the design is meant for straight-line comfort over long distances.

Weight Issues
One of the significant drawbacks is the shoe’s weight. The men’s size 10.5 comes in at over 11 ounces, which is quite hefty by modern standards. Even smaller sizes aren’t exactly lightweight, clocking in around 10 ounces. This added weight might not bother everyone, particularly for more leisurely or recovery runs, but it’s worth noting if performance is a top priority.
Fit and Sizing Challenges
The Cloudmonster 2’s fit is all over the place. Most runners will need to size down, sometimes even more than just a half-size. If the fit is off initially, expect a lot of roominess, especially in the toe box. On the flip side, if you have wider feet, you might actually appreciate the extra space. The lacing system does allow for a good lockdown, so it’s possible to achieve a decent fit eventually.
Performance on the Run
In terms of actual performance, the Cloudmonster 2 delivers a stable and cushioned ride that’s perfect for longer runs. The firm foam and rocker motion keep you rolling forward efficiently, though the shoe’s heaviness can become noticeable during extended efforts. This shoe excels as a daily trainer for those who appreciate a firmer, more grounded feel. However, it might fall short for those looking for a lighter, more responsive option.

Conclusion
The On Cloudmonster 2 offers a blend of unique style and sturdy performance, making it a compelling choice for casual runners who want something different. Despite its weight and sizing quirks, the Cloudmonster 2 delivers reliable stability and cushioning, ideal for long, straight-lined miles. While it might not displace your go-to trainers, it’s definitely worth adding to your rotation if you’re curious about On’s innovative approach to running shoes.
