The On CloudMonster 3 is the newest version of On’s max-cushioned running shoe, and I’ve spent weeks putting it through its paces to see if it actually delivers on its bold design and premium price. At £190, it’s definitely a high-end choice in a market already full of maximalist trainers.
Here’s my honest take on how the CloudMonster 3 performs, whether the fit and comfort make the price worth it, and who’ll get the most out of this eye-catching trainer. If you’re thinking about adding these to your rotation, this should help you figure out if they’re the right fit for your running plans.
Performance and Ride Experience
The Cloudmonster 3 gives you a firm, mechanical ride that’s all about forward momentum, not plushness. The triple-layer CloudTec system, paired with the Speedboard, creates a feel that’s more propulsive than soft. It works for everything from recovery walks to quicker tempo runs.
Cushioning and Energy Return
The CloudTec midsole uses Helion foam for a firm but protective feel underfoot. When you land, the pods compress and snap back fast. It’s a different sensation from the soft, sinking feel in most max-cushion shoes.
The 35mm stack height soaks up impact on long runs. I found the cushioning especially effective on concrete, where the foam took the edge off repeated pounding without feeling harsh.
The Speedboard adds some tension through the midfoot, keeping the ride snappy and stopping it from feeling mushy. I pushed these to 7:00 per mile tempos and the pop kept things lively, not sluggish.
The pods are noticeable when walking, giving a bouncy, almost playful feel that turns into a rolling motion once you’re running.
Stability and Support
The wide base and 6mm drop give the shoe a stable feel for daily training. The CloudTec pods compress evenly, so you don’t get much side-to-side wobble.
With 35mm of stack, you do notice the height on sharper turns. It’s fine for road running, but not built for tight corners or technical trails.
The rocker shape and Speedboard help guide your foot through each stride, so the Cloudmonster 3 feels stable even at quicker paces where some high-stack shoes get a bit wobbly.
The redesigned upper holds the midfoot securely without needing to crank down the laces. My foot stayed put during transitions, which helped with stability at faster paces.
Suitability for Daily Training and Long Runs
The Cloudmonster 3 shines as a daily trainer for racking up miles. It keeps your legs protected on 15 to 20-mile runs and still feels responsive enough for steady tempos. The firm ride keeps things fresh without weighing you down.
At 10.4oz, you’ll notice the weight if you’re doing speed work or intervals. It’s not made for all-out sprints or track days; it’s better for steady efforts where impact protection matters more than speed.
The upper breathes well on hot days. I never got that stuffy, overheated feeling you sometimes get with thick uppers, so these work well for summer training.
Durability and Shock Absorption
The Helion foam and CloudTec pods should easily get you past 300 miles, based on previous models. The outsole rubber grips well on both dry and wet pavement, and I didn’t see any early signs of wear.
The shock absorption stands out. The triple-layer setup handles repeated pounding on concrete and tarmac without feeling harsh or bottoming out. My joints felt protected even on back-to-back long runs.
The pod gaps don’t pick up stones or debris like older CloudTec models. I ran on regular roads and didn’t have any issues with rocks getting stuck, which used to be a complaint.
The outsole gives steady grip, even on slick morning roads. The rubber stays consistent across different surfaces, so you can trust your footing in typical weather.
Fit, Comfort, and Value
The Cloudmonster 3 fits true to size for most, with a roomier toebox than earlier versions and a price at £170, putting it up against premium trainers.
Sizing and Width Options
The toebox is noticeably roomier than the Cloudmonster 2, which is great if you’ve got wide feet or just want more space up front.
If you’re between sizes, I’d still stick with your regular size. On doesn’t offer official wide widths, but the updated fit works for a lot more foot shapes than before.
Price and Comparisons
You’re paying for On’s unique CloudTec tech and that recognizable brand look. The build quality feels solid. The outsole and midsole suggest these should last 400-500 miles if you rotate them.
Value really depends on your preferences. If you want a softer, more traditional max-cushion ride, the Bondi 9 or 1080 v15 might be a better deal. But if you’re after firm, responsive cushioning with that unique On vibe, the price makes more sense.
User Profiles and Suitability
I really enjoyed them for long, steady runs when I wanted protection but still wanted to feel connected to the ground. They’re a great match for neutral runners putting in serious road miles.
If you’re after a plush recovery shoe for those easy days, honestly, these probably won’t hit the mark. The firmness just doesn’t lend itself to slow, gentle jogs, some folks will find them a bit too stiff for that.
The midsole and outsole grip gave me more confidence on uneven ground. Versatile enough for walking too, but at £170, it’s a tough sell just for casual strolls.
