The Original

Why the Cloudmonster 61 Still Belongs in Your Rotation

The number 61 does not mean much on its own. But in the On Cloudmonster world it means everything. The Cloudmonster 61 is the original model, the silhouette that launched in spring 2022 and immediately made American runners stop and take On seriously as a performance brand for the first time. Before the 61, On was the brand you saw on suburban dads and college campuses. Stylish, sure. But serious running shoe? Not quite. The Cloudmonster 61 changed that argument in a single season.

What made it so different was the combination of things no max-cushion shoe had pulled off together before. Massive CloudTec pods that compress independently on every landing, absorbing shock vertically and horizontally at the same time. Helion superfoam in double the quantity of any previous On model, giving you a midsole that is genuinely soft on tired legs without turning mushy under load. An embedded Speedboard nylon plate that stores kinetic energy on landing and releases it at toe-off, giving you a pop of propulsion that max-cushion shoes almost never deliver. And a rocker geometry that mechanically assists your heel to toe transition so your calves and Achilles are not paying full price on every single mile.

That combination still works. It worked when the 61 launched and it works today. Runners who have cycled through the Cloudmonster 2 and Hyper and 3 still come back to the 61 because the ride feel is unique, the value with up to 30% off is undeniable, and there is something genuinely satisfying about running in the shoe that started it all.

What You Get

What the Cloudmonster 61 Delivers Every Single Run

Original Monster CloudTec Geometry

The largest CloudTec pods On had ever engineered at the time of launch. Each pod compresses independently on impact, absorbing shock in multiple directions simultaneously. At toe-off they lock together into a unified firm platform for explosive forward propulsion. No other shoe in this class does both of those things in the same stride.

Double Stack Helion Superfoam

On packed double the Helion foam into the 61 compared to any previous model. The result is a midsole that is genuinely soft on tired legs but does not bottom out under heavy runners or long efforts. It cushions on landing and bounces back for the next step. That is what good foam is supposed to do.

Speedboard Nylon Plate

Embedded between the layers of Helion foam, the Speedboard flexes as you load the shoe and snaps back at toe-off, adding a mechanical boost to every step. It is the reason the Cloudmonster 61 feels faster than a max-cushion shoe has any business feeling. That extra pop is real and you notice it from the very first run.

6mm Drop Rocker Profile

A natural 6mm heel to toe drop with an aggressively curved rocker midsole shape. The geometry does the work of transitioning you through your gait cycle so your plantar fascia, Achilles, and calves absorb less cumulative stress per mile. On long training runs the difference is felt in how your legs recover the next morning.

Recycled Polyester Mesh Upper

The 61 upper is constructed from recycled polyester, lightweight, breathable, and built to handle American running conditions from humid Gulf Coast summers to dry Southwest heat to damp Pacific Northwest mornings. It disappears on your foot during a run because the best uppers always do.

High Abrasion Rubber Outsole

Strategic rubber placement in the highest impact zones means the Cloudmonster 61 holds up through 400 to 500 miles of real road running. The CloudTec pods are durable by design and the rubber protects the areas that take the most punishment from American pavement every single day.

Sizing

Sizing for the Cloudmonster 61

View Full Size Guide

The Cloudmonster 61 runs slightly small. The rockered forefoot creates a shallower toebox profile that catches a lot of runners off guard. The consistent advice from the US running community across thousands of purchases is to go up half a size from your normal running shoe size. Men's 10 becomes a 10.5. Women's 8 becomes an 8.5. If you are between sizes, always size up. If you have a wider foot, the 61 is the widest On shoe from its era which works in your favor. Still not sure? Our size guide has the full breakdown and our team is ready to help before you place your order.

Who It Is For

Who the Cloudmonster 61 Was Made For

This is not a shoe for everyone. But if any of these describe you, it is absolutely the shoe for you.

You Want the Original Cloudmonster Experience

The Cloudmonster 2 added more cushion. The 3 added more layers. But the 61 is the source. If you want to run in the shoe that defined what the Cloudmonster ride is supposed to feel like before any revisions and updates, the 61 is the only answer.

You Are a High Mileage Runner Who Needs Daily Protection

Training for a half, a full, or just logging consistent 40 to 50 mile weeks? The Cloudmonster 61 handles back to back training days with its protective stack and forward-rolling geometry. It absorbs enough impact to keep your joints healthy through a full training cycle.

You Tried Other On Shoes and Found Them Too Firm

The pre-Cloudmonster On lineup was notoriously stiff. Runners who bounced off the Cloudflow or Cloudswift because the ride was too firm almost always find the 61 to be the On shoe they were waiting for. Double the foam, genuine cushioning, and a rocker that smooths everything out.

You Want a Max Cushion Shoe That Still Has Energy

Most shoes in the max-cushion category make you feel like you are running through wet sand on anything faster than an easy pace. The Cloudmonster 61 does not. The Speedboard and CloudTec locking mechanism give you genuine toe-off energy that competitive runners find surprising in a shoe this protective.

You Want the Best Value in the Cloudmonster Family

With up to 30% off, the Cloudmonster 61 represents the best dollar-per-performance value in the entire Cloudmonster lineup. You are getting the shoe that launched a franchise at a price that makes trying it for the first time a completely risk-free decision.

Deep Dive

On Cloudmonster 61: The Full Story Behind the Shoe That Changed On Forever

The Shoe That Made America Take On Seriously

In the spring of 2022, On was at a crossroads in the US market. The brand had built an impressive following among lifestyle consumers who loved the Swiss aesthetic and the minimalist CloudTec design. But the serious running community was skeptical and with good reason. On shoes were firm, the foam was thin by max-cushion standards, and runners who tried them for training quickly went back to their Hokas and Brooks and New Balances. The Cloudmonster 61 ended that conversation. It was the first On shoe that looked like a max-cushion trainer, felt like a max-cushion trainer, and still managed to deliver the kind of snappy forward energy that made you want to run faster than you planned to. US running specialty stores sold out of initial stock within weeks of launch. The reviews from the American running community were the best On had ever received on a performance product. The Cloudmonster 61 was not just a shoe. It was the moment On became a brand that elite and recreational US runners could both take seriously.

Why the 61 Ride Feel Has Never Been Perfectly Replicated

On has made three generations of the Cloudmonster since the 61 launched. Each one has brought genuine improvements in specific areas. More cushion in the 2. More responsiveness in the Hyper. More of everything in the 3. But a significant portion of the US Cloudmonster community still reaches for the 61 when they want that particular ride feel. The reason is the specific interaction between the original CloudTec pod geometry, the Helion foam density, and the Speedboard stiffness profile in the 61. It creates a ride that is snappy and alive in a way that subsequent versions, which prioritized cushion volume over ride character, have not perfectly replicated. If you have run in a Cloudmonster 2 and found it slightly flat compared to what you expected, the 61 is what you were expecting. It has more personality underfoot than almost any other shoe in the max-cushion category and that personality is exactly what built the Cloudmonster's loyal following in the US.

The Best Time to Buy the Cloudmonster 61 Is Right Now

The Cloudmonster 61 is no longer the newest shoe in the franchise. The 3 holds that title. But what that means for you as a buyer is that the 61 is now available at up to 30% off its original retail price. A shoe that launched at $170 is now accessible from $119 depending on the colorway and size. That is an extraordinary value for a shoe with this level of performance engineering. At www.oncloudmonster.com you are getting that price on authenticated On product with free shipping over $90, free 30-day returns, and delivery in 10 to 14 working days to anywhere in the US. The franchise has evolved but the 61 is still an elite daily trainer. Getting it at 30% off while stock lasts is the kind of deal that does not need much explaining.

Colorways Worth Knowing About

The Cloudmonster 61 launched in a handful of colorways that became benchmarks for the franchise aesthetic. The All Black, clean and versatile, became the default choice for US runners who wanted zero decisions in the morning. Alloy and Silver offered a more refined look that worked beyond running contexts. On the women's side, Ivory and Grenadine and Tan and Pink became the colorways that showed up on running paths from Brooklyn to Beverly Hills. The undyed colorways, which On introduced as part of their sustainability positioning, became quietly popular among runners who wanted something more understated. Whatever your preference, the colorway does not change the ride. Every Cloudmonster 61 delivers the same performance regardless of what color it comes in. Pick the one that you will actually enjoy lacing up every morning.
