Walk through any airport terminal or high-end grocery store right now. You’ll see that distinctive, perforated "Cloud" sole everywhere. It’s the On Mens Cloud 5 sneakers. They’ve basically become the unofficial uniform for tech bros, nurses, and commuters who value their arches. But let's be real—seeing a shoe everywhere doesn't always mean it's the best tool for the job.
I’ve spent months looking at how these things hold up. On, the Swiss company founded by Olivier Bernhard, Caspar Coppetti, and David Allemann, didn't just stumble into this. They engineered a specific sensation. It’s "running on clouds," supposedly.
The Cloud 5 is the evolution of their flagship model. It’s lighter than previous versions and, honestly, a bit more refined. It’s the shoe you grab when you’re running late and can’t be bothered to tie laces. That's the selling point. It’s convenience wrapped in Swiss engineering.
What’s Actually New in the On Mens Cloud 5 Sneakers?
Most people don't realize the Cloud 5 isn't just a re-release. It’s a total overhaul from the older Cloud 4.0. The midsole is thicker. They used a higher percentage of recycled materials—about 44% total. That's a huge jump.
The fit changed too. If you ever tried the older models, they felt narrow. Like, "squish your toes until they go numb" narrow. The Cloud 5 fixed that with a bit more volume in the forefoot. It’s still a slim-looking shoe, but it doesn't feel like a vice grip on your metatarsals anymore.
Then there’s the speed-lacing system. This is the hallmark of the On Mens Cloud 5 sneakers. You don't tie them. You just slide your foot in. The elastic laces maintain tension. It sounds like a gimmick until you’re juggling a toddler and a latte and need to get out the door in ten seconds. For the traditionalists, they still throw a pair of classic laces in the box, but almost nobody uses them.
The Tech Beneath the Surface: CloudTec and Speedboard
Let’s talk about that Swiss cheese sole. It’s called CloudTec. Those little hollow pods (or "clouds") compress horizontally and vertically. When you hit the pavement, they collapse to absorb the shock. Then, they lock into a firm base for your takeoff.
Inside that foam is the Speedboard. Think of it as a liquid-injected plate of thermoplastic polymer. It sits between the upper and the midsole. Its job is to flex and then snap back. It converts the energy of your landing into forward motion. It’s why these shoes feel "snappy" rather than "mushy" like a pair of Hoka Bondis.

Performance vs. Lifestyle: The Great Divide
Are they running shoes? Technically, yes. Would I recommend them for a marathon? Probably not.
The On Mens Cloud 5 sneakers are built for "urban exploration." That’s marketing speak for walking a lot on concrete. If you’re hitting the gym or doing a light 5k, they’re fantastic. But for serious long-distance training, they lack the high-level cushioning and structured support found in the Cloudmonster or the Cloudsurfer.
The Cloud 5 is a lifestyle shoe disguised as a performance trainer. It excels in the "all-day" category. If you’re a doctor on a 12-hour shift or a traveler walking 20,000 steps through Rome, this is your shoe. It stays comfortable because it's insanely lightweight—we’re talking roughly 250 grams. You almost forget you’re wearing them.
Breathability and the "Hot Foot" Problem
One thing On nailed is the antimicrobial mesh. It’s breathable. Really breathable.
I’ve seen plenty of guys wear these without socks. While I wouldn't personally recommend that for the longevity of the footbed, the airflow is legit. It keeps your feet cool in July. The downside? These are not "wet weather" shoes. That mesh lets water in just as fast as it lets air out. If you live in Seattle or London, you might want to look at the Cloud 5 Waterproof version instead. The standard mesh will soak through in a light drizzle.
The Durability Question: How Long Do They Last?
Here’s where we get into the weeds. I’ve talked to dozens of owners. The consensus is mixed.
The CloudTec pods are brilliant for comfort, but they have a fatal flaw: rocks. If you walk on gravel, you will eventually pick up a passenger. A small stone will get wedged in the central channel of the sole. It’s annoying. You’ll hear a click-clack on the sidewalk and realize you have to perform surgery with a car key to get it out.

The outsole durability has improved in the Cloud 5, though. They reinforced the traction pads. In previous versions, the foam would wear down to nothing in a few months. Now, the rubber compounds are tougher. You can expect 300 to 400 miles of walking before the grip starts to fail.
Sizing Advice You Actually Need
Listen closely: buy a half-size up.
Despite the "new and improved" fit, the On Mens Cloud 5 sneakers still run a bit small compared to brands like New Balance or Brooks. If you’re a 10 in a Nike Pegasus, you’re almost certainly a 10.5 in these. Also, the heel cup is relatively low. If you have high-volume feet or use custom orthotics, the fit might feel a bit shallow.
Aesthetics and Why Your Boss is Wearing Them
There is a certain "tech-minimalist" aesthetic that On has mastered. The colorways are usually muted—clays, navys, blacks, and sands. They don't scream "I just came from the track." They look intentional.
This is why they’ve exploded in corporate environments. You can wear a pair of Triple Black Cloud 5s with chinos and a button-down, and you don't look like you gave up on life. It’s a "performance" look that fits in a boardroom. It says you’re active, you value engineering, and you probably have a standing desk.
Sustainability is More Than a Buzzword Here
On is trying. They aren't perfect, but the Cloud 5 uses a significant amount of recycled polyester. The "do-good" factor is part of the brand identity. They even have a subscription service called Cyclon for other models where you recycle the shoe entirely. While the Cloud 5 isn't part of that specific circular program yet, the move toward 44% recycled content is a step in the right direction for a mass-produced sneaker.
Common Misconceptions About the Cloud 5
People think the "clouds" will pop. They won't. They aren't air-filled like a Nike Air Max unit. They are structural foam. If you puncture one, nothing happens. The shoe keeps its shape.

Another myth is that they are "orthopedic" shoes. They aren't specifically designed for people with severe overpronation or fallen arches. They are neutral shoes. If you need heavy-duty stability, the Cloud 5 might actually feel a bit too flexible for you. You’d be better off looking at the Cloudflyer.
Real-World Use Cases: Where the Cloud 5 Shines
- The Airport Hustle: This is the undisputed king of TSA lines. No laces to faff with. Easy off, easy on.
- Office Commuters: If you walk a mile from the train to the office, your knees will thank you.
- Light Gym Work: Great for lifting and rowing machines. The flat-ish profile of the Speedboard provides a decent stable base for squats, though they aren't dedicated lifting shoes.
- Hospital Shifts: Nurses swear by them for the weight alone. When you're on your feet for 14 hours, every gram matters.
The Competition: Cloud 5 vs. The World
How does it stack up against the Allbirds Tree Dashers or the Nike Free?
Allbirds are softer, sure. But they lack the structure of the On Mens Cloud 5 sneakers. Allbirds feel like a sock with a sole; the Cloud 5 feels like a piece of equipment. Compared to the Nike Free, the On has much better energy return. The Speedboard really does make a difference in how "alive" the shoe feels underfoot.
But if you want pure, squishy comfort? New Balance Fresh Foam or Asics Novablast will beat the Cloud 5. The Swiss shoe is for people who want a firmer, more responsive ride. It’s a "sporty" feel, not a "pillowy" one.
Is It Worth the $140 Price Tag?
Let's talk money. At $139.99 (usually), these aren't cheap. You’re paying for the R&D, the Swiss branding, and the specific aesthetic.
If you want a shoe that does everything reasonably well—looks good, feels light, and lasts a year of daily use—the investment makes sense. If you’re a hardcore runner looking for a marathon PB, your money is better spent elsewhere.
Honestly? Most people buy them for the "cool factor" and stay for the convenience of the speed laces. It’s a lifestyle upgrade. It simplifies your morning routine.
Actionable Steps for Buying Your Pair
Don't just click "buy" on the first pair you see.
- Check your gait: If you heavily roll your ankles inward (overpronation), go to a store and try them on first. The Cloud 5 is a neutral shoe and might not give you the support you need.
- Size up: Seriously. Order a half-size larger than your standard dress shoe or casual sneaker.
- Consider the color: The lighter colors (like "All White" or "Sand") look incredible but they stain easily and the mesh is hard to clean. If you're a daily commuter, the "Zinc/White" or "Black/White" colorways hide city grime much better.
- Test the laces: When you get them, try the speed laces for three days. If you hate the "slipping" feeling, swap them for the traditional laces included in the box before you decide to return them.
- Look at the terrain: If your daily walk involves gravel paths or woodchips, be prepared to pick stones out of the sole. If that sounds like a dealbreaker, look at the Cloudultra, which has a closed-channel sole designed to prevent that exact issue.
The On Mens Cloud 5 sneakers are a specific tool for a specific lifestyle. They aren't the softest shoes on the market, and they aren't the cheapest. But they are arguably the most versatile "everything" shoe for the modern urban environment. They bridge the gap between performance and style in a way few other brands have managed to stick.
