On Cloudrunner Review
1st Released Year: 2022
Official Price: $149.99
Launched in early 2022, the On Cloudrunner is one of On’s most supportive shoes designed with more cushion and more comfort than ever before.The Cloudrunner uses a Zero-gravity foam that provides a firmer, more responsive feel than the Cloud Flyer. It’s good for tempo runners or runners who prefer faster speeds over longer runs.This is the type of shoe you just slip on and go. Forget gravity, and anything else that’s weighing you down.
The shoe still features On’s famous CloudTec elements for explosive takeoffs and soft landings, ultra light zero-gravity foam midsole for a smooth ride, as well as a Speedboard.Due to the wide outsole under the forefoot,the Cloudrunner has excellent stability. This solid platform reduces the likelihood of lateral roll in your ankles and allows you to comfortably power on through your long runs.The Cloudrunner also offers a softer and more plush upper, with more padding in the tongue and around the heel collar.
The On Cloudrunner can be seen as a little sister of the more cushioned On Cloudflyer. While both provide inherent stability and support, the Cloudrunner has slightly less cushion and uses Zero-gravity foam while the Cloudflyer uses Helion foam.Although the Cloudrunner is less cushioned, it’s priced at $149.99, making it more affordable than the $169.99 Cloudflyer.
Who Is the On Cloudrunner Best For:
Regular road runners who want a supportive and cushioned shoe for their easy or longer runs.
New runners who want a supportive all-round shoe.

On Cloudflyer 4 Review
1st Released Year: 2017
Official Price: $169.99
Cloudflyer debuted in 2017 as a lightweight low stability shoe and has changed quite a bit since, moving more “stability” and less “lightweight.”The Cloudflyers are On’s mid-tier version of a lightweight moderate stability shoe. It is meant for runners who need stability but also want less bulk and weight.
It features a bigger, dual-density CloudTec midsole and a wider platform that both provides a bit of stability and support as well as extra roominess for wider feet.Perfect for those with flexible arches or who overpronate, this shoe gives you stability in all of its details—it has an external heel counter, a star lacing pattern and a new molded sock liner. Lastly, a plush and comfortable upper wraps around your foot to give you plenty of support as you run.The upper is plush with a thicker knitted liner that makes for a lower volume fit in the forefoot with a secure and slightly snug fit elsewhere. The ride is extremely firm and strongly rockered, which combined the weight makes it better for slower efforts and walking.Because the Halion Foam is more flexible, it is ideal for those looking for more mileage and extra protection, especially for those who use it for daily activities or recovery runs.Although they are quite pricey, the benefits justify the heavy price tag.
Who is the On Cloudflyer Best For?
Runners who need extra support, but still want a lightweight long-distance shoe.
Mild to moderate overpronators.
Runners who prefer a firm midsole and want a stable shoe.
Individuals who value premium-quality materials and require a versatile running shoe.

On Cloudgo Review
1st Released Year: 2022
Official Price: $149.99
New in 2022, the neutral trainer Cloudgo brings low-key comfort with a more standard outsole into On’s lineup.The On Cloudgo brings together top comfort, a smooth ride, and a Cloud base that collects fewer rocks than other Ons. This shoe brings a smile during regular runs and day-long wear.
The shoe features On’s outstanding CloudTec cushioning and signature Speedboard to give you shock-absorbing performance and propulsive energy.The Helion foam cradles your foot to give you a comfortable feel from your first step to your last. The CloudGo upper is made of 85 to 90% recycled material and the mesh feels soft to touch. The tongue and heel cup are adequately padded and give the shoe a very plush, almost luxurious feel. The heel cup consists of a half plastic cup that gives the shoes a good grip of your heel. The lacing holes are quite far apart, which together with the overlays that run from the base of the shoe through the upper, allows you to increase or decrease the volume depending on the volume of your feet. This roomy, adjustable upper gives a good fit to a large variety of foot volumes and shapes.
The On Cloudgo is a surprisingly high-performing On Cloud running shoe and one I believe all sorts of runners from beginner to advanced, will enjoy.
Who is the On Cloudgo Best For?
Casual and/or advanced runners who prioritize comfort in their daily trainers.
Runners who want a speedy shoe that isn’t stiff.
Runners who need a neutral/stable shoe that offsets pronating strides.
Those looking for a road shoe that’s comfy and stylish enough for walking around town.

On Cloudmonster Review
1st Released Year: 2022
Official Price: $169.99
The Cloudmonster is On’s softest, most cushioned trainer and extremely fun to run in.The Cloudmonster has On’s biggest ever CloudTec and a lot of springy Helion super foam cushioning underfoot without sacrificing energy return, while simultaneously providing performance boost.These ultra-cushioned shoes combine a radical rocker profile with a snappy Speedboard to deliver a delightfully offbeat experience during your run.
The Cloudmonster is built for pounding out miles on the road. They’re incredibly responsive, with great energy return and a strong rocker, which helps provide a smooth transition from landing to take off. The combination of these fine details really helps to reduce leg fatigue on long runs.The material of the shoe is also very breathable and durable, made with 35% recycled materials and minimal seams, to help reduce any chance of rubbing. The sole also has enhanced grip, with multidirectional patterns, as well as a shallow gully to stop any chance of gravel or stones getting caught - something some of the older models lacked.The sock liner is thin yet supportive, allowing breathability without causing the foot to slide around. There’s also no heel slippage or unwanted blistering due to the snug fit. A wider toe box allows the toes to spread out naturally, contributing to more comfort and stability while running.
Overall.The Cloudmonster is a lightweight, robust, and temperature-resistant shoe that will maximize your running performance.
Who is the On Cloudmonster Best For?
Runners who want maximum cushioning on their road runs.
Long-distance runners preparing for longer events such as half-marathon or marathon.
Runners looking for a multi-use shoe they can wear from park runs to races.

On Cloudrunner vs. Cloudflyer vs. Cloudgo vs. Cloudmonster: Side-by-Side Comparison
1.The Upper
On Cloudrunner - On Cloudrunner features engineered mesh upper.It is a double layer of mesh that is durable. The mesh showed minimal wear and tear after 100 miles in. Comfort continues in the upper. The double mesh provided ample cushioning from heel to toe. There was a medium amount of cushioning in the heel. It has a standard heel counter similar to those used in other trainers. It held your foot in place for the most part aiding in the stability of the trainer.While the upper is durable it lacks breathability slightly.
On Cloudflyer 4 - The upper is plush with a thicker knitted liner that makes for a lower volume fit in the forefoot with a secure and slightly snug fit elsewhere.I find the thin laces of the On Cloudflyers to be a drawback.They are the thinnest laces I have seen on a pair of running shoes. They became undone on occasion if they were not double-knotted. The star lacing system would be more effective and noticeable with thicker laces.
On Cloudgo - The CloudGo upper is made of 85 to 90% recycled material and the mesh feels soft to touch.The upper is soft and comfortable throughout, moderately breathable.On promotes Cloudflyer’s tongue as their “plushest ever,” but Cloudgo’s tongue is a touch thicker and is also wider to cushion more of the foot. Laces run through a reinforced loop on the tongue to keep it in place.
On Cloudmonster - On rarely disappoints with their uppers and the Cloudmonster is no different. The fit is incredibly comfortable and the insides feel velvety smooth. The Cloudmonster’s upper also doesn’t feel over-built like a lot of other max-cushioned trainers which have an excess of padding.It has a burrito-style tongue which wraps around the foot and it’s attached on both sides. The tongue is thin and flat but you don’t feel the lacing pressure on top of your foot.
2.The Outsole
On Cloudrunner - The outsole of the ON Cloudrunner is covered in CloudTec Rubber. With thicker coverage in the forefoot and heel to handle impact and lift offs. This is a wise choice because it shows some wear after 60 miles. The tread is on the lighter side so it struggles a bit in wet conditions.
On Cloudflyer 4 - Rubber patches cover much of the forefoot, the back heel pods, and late lateral midfoot pod to protect these higher abrasion areas and provide grip together with ridges cut into the foam of the exposed Cloud pods.
On Cloudgo - Thin rubber patches cover much of the outsole which is split by three horizontal flex grooves and and an almost full-length vertical divide. These segments allow for flexibility while a wide base and Speedboard bring enough stability to make this shoe appealing to a wide range of runners.Grip is average, and durability is low, though the rubber covering is slightly thicker below the heel than forefoot.
On Cloudmonster - There are 5 horizontal rows of clouds which form the Cloudmonster’s outsole. There’s rubber coverage on the heel as well as on the forefoot so the high wear areas have protection.The Cloudmonster isn’t a tough workhorse like the Infinity Run 3 or the Triumph 19 so the outsole and midsole have a considerably lower lifespan. Grip is however also very good because the exposed rubber of the Clouds feels very tacky on most surfaces.
3.The Midsole
On Cloudrunner - The Cloudrunner uses a Zero-gravity foam that provides a firmer, more responsive feel than the Cloudflyer. It’s good for tempo runners or runners who prefer faster speeds over longer runs. Zero gravity foam is a lightweight compound used for the midsole. It is a plush compound offering a comfortable ride from the first step. Between the foam and the cloudpods the Cloudrunner offers a bouncy ride.The cloudpods are enveloped by the zero gravity foam instead of being individual which gives it this feeling. The downside to all this comfort and plushiness is the lack of an energy return.
On Cloudflyer 4 - The midsole features two columns of cloudtec elements with a midline groove in the heel and midfoot that transition into a full width forefoot. The full length Helion foam is quite firm and a highly curved sole design makes for a rockered ride.
On Cloudgo - The Cloudtec midsole is said to be the brand’s Helion™ Superfoam which combines rigid and flexible elements for a soft yet supported ride. It feels great underfoot—really a cloud-like ride—and only seems “squishy” at times under the heel.Given the softer foam throughout the base, the transition heel to forefoot is not a quick as in Cloudflyer, but a forefoot rocker plus spring from the board in Cloudgo get the runner quickly into toe-off.
On Cloudmonster - On still uses Helion foam in the midsole of the Cloudmonster but the major difference is that the stack is much higher, so there’s a higher rate of compression.The Cloudmonster has a single layer of clouds with each Cloud having a large hole in the middle of it that allows for it to compress.This setup results in a softer underfoot feel than a dual layer of small Clouds with small holes in the middle of each cloud like in some of On’s other max-cushioned trainers.
4.The Fit
On Cloudrunner - The fit is true to size.If you usually wear a wide fitting shoe, these may be a little too snug for you in the standard size, but they do offer a wide fit option.
On Cloudflyer 4 - This shoe fits well!The upper is plush with extra padding throughout. The height feels lower because of this, especially in the forefoot and almost made the shoe feel short. This material immediately broke in and began to feel true to size.
On Cloudgo - Cloudgo fits true to size for length.
On Cloudmonster - The fit of the Cloudmonster runs a half size large so I suggest sizing down because it has extra length. It has a narrow midfoot, forefoot and toe box.The toe box also feels shallow. It’s definitely not suitable for wide feet or high volume feet.

Conclusion:Which One Should You Choose?
The On Cloudrunner is a great stable option from On. If you are looking for a high cushion option with stability, the Cloudrunner is definitely a good option. It was a shoe that was missing in On’s lineup. However,Its lack of responsiveness holds them back from being a true daily trainer ready to handle any type of workout you throw at them. It also lacks breathability because of the second layer of the engineered mesh.
Cloudflyer is quicker into toe-off and more responsive underfoot with greater ground feel.CloudFlyer shoes should be chosen by those who prefer maximum cushioning stability and a great ride for long runs or recovery days, and those who choose shoes for everyday life or tempo runners.
Cloudgo is moderately plush for comfort and buoyant underfoot. The Cloudgo fits the mold of a daily trainer but doesn’t extend far beyond that performance threshold.Soft and responsive, the Cloudgo offers suitable performance for easy and moderate pace efforts but seems to wear prematurely.At a medium-high price point, this shoe feels like it could use a few slight improvements.
The Cloudmonster is designed to be a max-cushioned trainer but it doesn’t possess the plushness or the marshmallow-soft ride.However,it is a great daily trainer because of how versatile it is.
Frequently Asked Questions (FAQs)
Is the on Cloudrunner a stability shoe?
The Cloudrunner is made for every runner looking for a stability shoe that feels comfortable and responsive for any race you are training for. From the first step into the shoe until the end, there is comfort for every step along the way.
Is Cloudrunner neutral or stability?
The Cloudrunner is a workhorse daily trainer for those with mild stability needs, but still may work well for those with neutral mechanics as well.
Is Cloudrunner good for overpronation?
The midsole of Cloudrunner cuts away less at the arch, which naturally adds to the support the shoe offers you through your stride. In addition, the clouds are smaller with more cushioning material packed around them, which increases protection against over-pronation, plus extra cushioning.
What are Cloudrunner shoes good for?
Whether you're a new runner, just getting back into running, or just looking for a regular training shoe, the Cloudrunner combines the soft feel you want with the support you need. Run more, go further and keep your feet in the comfort zone with the Cloudrunner.
Should I size up or down in Cloudrunner?
Usually, your best bet is to go with your regular size. If you jump between half-sizes often though, it's better to go with the half-size up. Wider feet struggle to find the perfect fit since the Cloud features a narrow toebox and a roomier heel.
Does Cloudrunner come in wide?
The cushioned, supportive running shoe that offers a unique comfort sensation in a wide fit.
Are on Cloudgo good for running?
The CloudGo is there to do the bulk of your easy, slower running.
What is the Cloudgo for?
Those looking for a shoe to wear sockless should consider the Cloudgo. The width is normal in the heel and midfoot while being snug in the forefoot. The forefoot tapers somewhat but the mesh does stretch and provide room.
Is Cloudgo a neutral shoe?
Unlike its mild support sibling, the Cloudrunner, the Cloudgo is a neutral daily trainer with a full-length Helion midsole.
Are on Cloudmonster good running shoes?
Cloudmonster is one of the most comfortable and durable long-distance running shoes on the market. It can undoubtedly go the distance but may offer too much cushioning for the runner looking for a more slim-soled shoe.
What are on Cloudmonster shoes good for?
They're light enough to make a great 5K or 10K shoe too for the average runner.
Is on Cloudmonster good for wide feet?
The Cloudmonster won't be a good choice for the wide foot or high volume foot family out there. The trainer is narrow, and the toebox is shallow. If you are between sizes in your running shoes, err on going up a half size.
Are Cloudmonsters good for half marathon?
From training sessions to the half marathon itself, these shoes offered responsive support and exceptional comfort. They excelled in easy runs, long runs, and recovery efforts, making them versatile and reliable companions for any distance.
Does Cloudmonster have a carbon plate?
Above the clouds there is a plate, that holds the whole midsole structure together. It's not a carbon plate but still a plate and since the plate is placed high in the midsole with almost no foam above it, the sensation while running is rather firm.
