7 Best On Running Shoes in 2024
We earn affiliate commissions at no extra cost to you when you buy through us. Why trust us

On is a relatively new entry in the world of running. They started producing running shoes only in 2010, but since then they’ve grown to become a relevant brand. Whether it’s for the road or the trail, On running shoes have got what it takes to compete against established brands like Adidas and Nike.

We’ve carefully tested different models from On in different categories to help all runners pick the best based on their needs. Through our own shoe testing lab, we gather data that solidify our decision to choose the shoes on this list.

How we test running shoes

Apart from having our independent RunRepeat shoe testing lab, we also buy all the running shoes from On we scrutinise with our own money. This is to make sure we give you a 100% honest review. 

To be more objective, we also carry out the following: 

  • Run in each shoe for 30-50 miles to see how they perform and how sturdy they are when put through intensive use
  • Slice the shoe into pieces to see what’s inside and explore the shoe even deeper
  • Measure them in 30 different parameters like breathability, softness, thickness, weight, etc.

On Cloudsurfer 7

What makes it the best?

We sailed through our runs with Cloudsurfer 7’s soft landings, springy toe-offs, and flexible nature. Our lab findings reveal a perfect blend of light weight, luscious foam, and high stack, making it our top On running shoe. Its excellent impact absorption and high energy return keep us coming back.

Living up to the brand’s cloud-like trademark, the Surfer 7 boasts a 36.3/21.7 mm stack made of ultra-soft and bouncy foam. Our durometer measured the cushion at a low 20.4 HA, explaining its plush nature. What’s impressive is how it’s still 1.0 oz (28g) lighter than the average running shoe despite its cushioning.

Cloudsurfer 7 is speedy without relying on the stiff speedboard other On models feature. This is thanks to its high 14.6 mm drop and rockered geometry that promotes a smooth forward-rolling ride with quick and efficient turnover. 

Our runs felt energetic and easy to manoeuvre with its unopposing midsole. It’s one of the most flexible shoes we put against our flex test, sitting 57.2% above average. This feature fosters freedom of movement and a relaxed ride.

With its focus on comfort, Cloudsurfer 7 lacks stability for pronators. Those who need extra guidance are better off with more supportive shoes.


  • Excellent shock absorption and energy return
  • Soft and squishy midsole
  • Smooth and fun ride
  • Rockered design promotes buttery transitions
  • Great for short and mid-distance runs
  • Performs well at high speed
  • No speedboard means it’s no longer stiff
  • Super comfy upper
  • Snug and secure lockdown
  • Plush tongue prevents even a hint of lace bite
  • Lightweight for such a well padded shoe
  • Stylish and sustainability minded design


  • Overall issues with durability
  • Outsole could be grippier
  • Somewhat unstable at longer distances
  • Not ideal for heavy-set individuals
  • Pricey for a daily trainer

Best daily trainer On running shoes

On Cloudswift 3

What makes it the best?

The On Cloudswift 3 is a great all-rounder that looks as good as it performs and our outdoor runs and intensive lab tests confirmed this. Possessing a smooth and spirited ride, a top-notch upper, and tremendous durability, it is the best daily trainer in the On lineup.

A TPU plate (speedboard) embedded in the midsole foam provides structure and rigidity, explaining the springiness we felt during faster-paced workouts. The shoe’s rocker geometry, lively midsole foam, and 9.7 mm heel-to-toe drop blend seamlessly together to supplement the overall responsiveness. True enough, the smooth forward-rolling sensation only made us enjoy logging more miles.

There is noticeable padding around the ankle, heel, and tongue area, which means comfortable strides all the way. Our smoke test also showed that the Cloudswift 3 is excellent in terms of breathability (4/5). On our summer runs, our feet felt breezy and sweat-free even during long runs.

To test for durability, we conducted the standardised dremel test (3.4N / 4 secs) on the shoe’s toebox and the results were phenomenal. The shoe withstood the Dremel test when other shoes resulted in holes. The outsole also showed no visible signs of premature damage even after multiple double-digit runs. Using a HA Durometer, we also measured the outsole to be 6.9% firmer than the average, confirming its durability all the more. 

The Cloudswift 3 may be swift on the road, but it also swiftly tips the scales. At 309 g (10.9 oz), it really is a heavy shoe compared to the average of 265 g (9.3 oz). Runners looking for lighter shoes will want to check other options.


  • Comfortably snug upper
  • Immensely breathable
  • Secure lockdown from heel to toe
  • Responsive and protective cushioning
  • No break-in necessary
  • Smooth forward-flowing ride
  • Doesn’t collect debris as much as v1 and v2
  • Very good grip on various surfaces
  • One fine-looking runner
  • Solid sustainability elements
  • Best for daily training and easy runs
  • Also great for gym workouts


  • Slightly firm underfoot
  • Not advisable for long runs

Best On running shoes for speed training

On Cloudflow 4

What makes it the best?

The Cloudflow 4 seamlessly combines breathability and protection in its upper with a midsole that strikes the perfect balance of firmness, flexibility, and responsiveness. Its airiness effortlessly elevated our tempo sessions, making it our top speed trainer among lab-tested On running shoes.

At 8.6 oz (245g), Cloudflow 4 weighs lighter than the current lab average of On road-running shoes 9.6 oz (273g). Adding to its airiness is the thin upper that allows ventilation even without large holes. This setup makes it both breathable (4/5) and durable (3/5). This trainer includes a Speedboard plate that offers delightful energy return while maintaining our stability and form even in long runs. Needing only 22.0N of force to bend to 90 degrees in our flex test, it’s 24.9% more malleable than average. This promotes a forgiving ride, proving responsive shoes don’t have to feel overly rigid.

Cloudflow 4 offers a stable and supportive ride through its two Helion foams. Our durometer shows the lower layer is a firm 28.3 HA, while the top is an even denser 33.0 HA. In our runs, we felt this through heightened ground feel, surefooted strides, and our feet doing the work—the latter being an advantage for muscle strengthening.

We do not recommend this shoe for wide feet since it has a form-fitting upper and a midsole that’s 3.5 mm narrower in the forefoot.


  • No longer catches stones in the outsole
  • Extremely light and nimble
  • Effective rockered geometry
  • Provides a stable ride
  • Comfortable and durable upper
  • High-quality materials
  • Suitable for interval training speeds


  • Likely too expensive for the features provided
  • Narrow midfoot fit
  • The foam may be excessively firm

Best On shoes for race running

What makes it the best?

The Cloudboom Echo 3 exudes pure speed, fully deserving the ultimate racer title among On’s lineup. Its unique rockered shape, responsive cushioning, and snappy rigid plate help us fly through the miles, as our streets came to witness. Even our lab results prove it’s a high-performance shoe that can match other supershoes in the industry.

The undeniable energy return comes from the rigid and curved carbon plate embedded in the bouncy Pebax foam. During our flex test, the midsole demonstrated exceptional rigidity, requiring 65.0% more force than average to bend to 90 degrees. Powered by the latest Helion HF foam, known for its unparalleled responsiveness, and complemented by the rocker design, our strides were propelled forward effortlessly.

This racer doesn’t sacrifice comfort for speed. Its foam has a pleasantly firm feel, which our durometer confirms at a balanced 23.5 HA. The stack is a sky-high 38.6/28.4 mm to dampen repetitive landing impact and save our legs from fatigue.

Further enhancing our experience is the snug yet highly breathable upper, crucial for avoiding painful blisters and hotspots. Our light test reveals exceptional ventilation from the toebox to the midfoot areas, which explains its perfect breathability rating.

Unfortunately, we cannot recommend this pair to runners with medium to wide feet as it runs extremely narrow (107.0/78.1 mm) vs. the average (113.5/90.3 mm).


  • Well-cushioned for marathon distances
  • High-energy return from Pebax foam
  • Offers a responsive and bouncy ride
  • Exceptionally breathable upper
  • Excellent for 5K and 10K runs
  • Semi-gusseted tongue
  • A wonder for those with narrow feet
  • Made from premium-quality materials


  • Exorbitantly high price
  • Likely too narrow for most runners
  • Weight leans toward the heavier side

On running shoes with the best cushioning

What makes it the best?

On's innovative Cloudmonster Hyper doesn't just prioritise comfort; it offers a stable and dynamic ride, catering to all kinds of runs and runners. This unique supertrainer combines the speed of a racer with the flexibility and support of a daily trainer, setting a new standard in performance footwear. After comprehensive testing in the lab and out on the streets, we confidently claim Cloudmonster Hyper as On's best-cushioned running shoe.

The Cloudmonster Hyper boasts an impressive midsole, towering at 39.7/33.0 mm—a significant 6.1/8.0 mm increase over our lab average. Its dual-foam setup offers a forgiving and bouncy ride, with a firmer 28.8 HA foam in the heel for stability and a softer 21.3 HA top layer for propulsion and comfort. The CloudTec's compression and bounce add to the gentler feel underfoot.

Our toe-offs felt extra energetic. Surprisingly, this On shoe leaves out the Speedboard plate for enhanced flexibility. Our bend test proves its versatility, emerging 20.3% more malleable than average. 

Despite its height, our landings felt steady and controlled. Other than the midsole sidewalls that cradle our feet, it strongly resisted twisting, proven by its 4/5 torsional rigidity score in our manual assessment. During our runs, accidentally twisting our ankles seemed impossible.

However, the shoe is prone to hotspots because of its subpar breathability (3/5). Runners in warm climates need more ventilation.


  • Roomy upper
  • Lighter than the Cloudmonster 2
  • High-quality materials
  • Well-balanced stack and stability
  • Comfortable for easy runs
  • Durable outsole
  • Wonderful lacing system


  • High price
  • Not the best for heel strikers
  • Needs more ventilation

Best On running shoes for wide feet

On Cloudstratus 3

What makes it the best?

The Cloudstratus 3 proves its worth with each stride, offering versatility and comfort during our mixed-distance runs. Extensive lab analysis highlights its spacious platform, resilient midsole, and both propulsive and forgiving ride, making it the top choice among On running shoes for wide feet.

Cloudstratus 3 not only brings comfort but inspires confidence in our strides. It has an expansive landing base and a roomy toebox for our relief and sure-footedness. Our calliper reveals a 115.4/90.3 mm midsole, the forefoot notably being 1.9 mm wider than average. The toebox is a generous 101.0 mm that gently tapers to 81.8 mm in the big toe area, giving us room to swell without hotspots.

Staying true to On’s core, it features a firmer-than-average 27.6 HA Helion foam that feels a lot softer due to its “clouds” that absorb landing impact and spring us back with energy when it returns to its original form. Further enhancing a well-protected ride is its 35.3/26.2 mm stack.

Cloudstratus 3 features a nylon speedboard that adds spring to each step without the rigidity of a carbon plate. Our tests show it's 14.6% more flexible than the norm, ensuring a comfortable and relaxed feel.

While the Cloudstratus 3 boasts impressive features, its £190 price tag may lead to hesitation. For a more budget-friendly daily trainer, it's worth exploring alternative options.


  • Excellent impact dampening
  • Propulsive nylon speedboard
  • Smooth rolling ride
  • Can go the distance
  • Feels stable underfoot
  • Secure and comfy lockdown
  • Luxuriously padded tongue
  • Roomy toebox
  • Sleek and sustainably made upper


  • Higher than advertised drop
  • Stiff speedboard feels apparent at low speeds
  • Pricey at £190
  • Midsole voids catch debris

Best On running shoes for road-to-trail

On Cloudvista

What makes it the best?

A good hybrid shoe is a great addition to anyone's running shoe roster, whether new to off-road running or seasoned trail junkies. With its subtle yet grippy lugs, and well-cushioned midsole, the Cloudvista is easily our pick as On's the best road-to-trail shoe. 

The Cloudvista's understated lugs are definitely the star of the show. They're a millimetre shorter than the average trail shoe at 2.5 mm thick, according to our calliper measurements. This short and subtle lug configuration plays a major role in Cloudvista's capability as a hybrid by avoiding the blocky sensation that often comes when taking a trail shoe on the road. Instead, we enjoyed smooth transitions both on and off-road in the Cloudvista with no real trade-off in grip or traction. 

We tested the softness of the shoe's distinctly On midsole and found it to be 14.2% softer than average, with a durometer reading of 23.5 HA. This level of softness means that we enjoyed well-cushioned landings that felt just as protective when off-roading on softer dirt trails as when pounding the hard asphalt, while the midsole clouds provide a solid and energetic rebound that propels us forward. 

The shallow lugs also represent one of the shoe's main downfalls, as they're not nearly aggressive enough to tackle more difficult or gravelly terrain. This, in combination with the shoe's lack of a protective rock-plate, leaves our feet at the mercy of more technical trails.


  • Works great as a hybrid shoe
  • Grippy and durable outsole
  • Fun at high speeds
  • Highly breathable
  • Rockered for smooth heel-to-toe transitions.
  • Secure lockdown
  • No heel rub
  • No Lace bite
  • Environmentally friendly upper
  • Suitable for walking or hiking
  • Stylish for a trail shoe


  • Not for technical trails
  • Not a distance shoe
  • Doesn’t accommodate wide feet
  • Midsole catches debris

How to choose On running shoes

On shoes are immediately recognisable for their unique midsole (which has holes in it!) and for their name, which always starts with “Cloud”. They can’t be mistaken for another brand.

But how do you know which one is the perfect match for you?


To answer that question, let’s have a look at the type of terrain as well as your pace, distance, pronation, foot strike, and foot width.

Road or Trail? Where do you run?

Most shoes from On are meant for running on roads, but there are also a few options for trail running as well.

Get a road running shoe if you run mainly on paved surfaces, asphalt, tarmac, or track. The Cloudswift is an example of a road running shoe from On for short runs.

Keep in mind that some shoes of this kind can handle gravel as well, as long as they have a durable and grippy outsole, like the Cloudmonster.


Get a trail running shoe if trails, grass, rocky terrain, and mud are where you usually run. For example, the Cloudultra 2 is stable, feels light, and is very comfortable even for long runs.

On Cloudultra 2 lugs

Some models perform well on both roads and trails, and they are called door-to-trail, road-to-trail, or hybrid shoes. Within On, a great choice is the Cloudvista, which is a fun and forgiving shoe for running fast on pavement or mildly technical terrain.

On Cloudvista Heel tab

Remember that trail running shoes need to grip the ground and protect the feet much better, so they are usually sturdier, heavier, have better durability, and have a more aggressive outsole. 

On Cloudvista Outsole durability

On Cloudultra 2 Lug depth

Based on our calliper measurements, the common lug depth in trail shoes from On is 2.5 mm. This is shallower than the average 3.5 mm across trail shoes from all brands. So, if you are dealing with a lot of mud and slush, it's better to go for a brand with deeper lugs. Here are a few examples:

On running shoes based on pace

Another thing you must consider when choosing a shoe is what you intend to do with it in terms of training. 

Slow, fast, or faster?

Most road running shoes are divided into 3 categories:

  • daily trainers: they usually provide good cushioning and versatility for most runs. They are ideal for your day-to-day workouts at a slow pace
  • speed training shoes: get these shoes if you need to increase your pace or work on speed, as they are lighter and faster
  • racing/competition shoes: while many shoes for speed training are perfectly suitable for race day, those specifically made for racing are more performance-focused and can have an edge over other shoes in terms of speed

One shoe that can do it all

Based on what we said above, ideally, you should have more than one pair of shoes. That’s why most runners, usually, have one pair for daily training and one for speed training/races, or all the 3 shoes from the categories.

However, there are shoes that, with some limitations, can do a little bit of everything. 

If that’s what you need, look for shoes that are:

  • cushioned: some runners prefer no cushioning at all and go with minimalist shoes, but most people prefer the protection and comfort that a good layer of foam gives underfoot. Most On shoes come with a heel stack of at least 30 mm, which is plenty protective.
  • responsive: this means that the shoe rolls forward quickly and smoothly, and can provide energy return at each step you take. In short, it makes it feel easier to run
  • light: look for a shoe that weighs less than 10.6oz (300gr) so that it doesn’t weigh you down when increasing the pace


Here are some of the highly-rated On shoes that meet the criteria above:

Going far? Get the right On running shoe

If you love very long runs, such as 40-50km and beyond, there are also shoes specifically made for that purpose. Normally, they have a great amount of cushioning for protection (at least 30 mm in heel stack), are slightly wider to let the foot expand once swollen, and usually are on the softer side underfoot.


On Cloudmonster (great for marathons and ultras)

*Midsole softness: lower HA reading means softer cushioning

The right On shoe for your pronation type

Every foot is different and some runners have neutral pronation, while others have supinating feet or overpronation. Running shoes should be chosen according to the type of pronation and the type of arch.

Here is a helpful graphic to understand the difference:

Arch types and recommended shoes.png

If you find out that you need extra support for your arches, go for a stability running shoe from On. Otherwise, choose a neutral model.

If you are still in doubt about your case, check out our guide on arch support to get a more in-depth idea and try the wet-paper test that is explained in it.

A shoe with good support won't let your arches and ankles collapse inward.

In our lab, we assess each shoe's stability more in-depth by evaluating their torsional rigidity and heel counter stiffness as well as measuring their platform width.

On Cloudstratus 3 Midsole width in the heel

You can see how the brand's stability shoes fare against each other in the table below:

On shoes for narrow, normal, and wide feet

Even in the act same size, running shoes can vary in width. Although the width can be narrower or wider at the heel, it’s at the midfoot and at the forefoot where we can feel it most.


We use a calliper to measure each On shoe's forefoot width precisely. We apply the tool to both the widest part of the toebox as well as to the narrower part (near the big toe) to check whether it is aggressively tapered or not.

On Cloudeclipse Toebox width at the widest part

Having lab-tested more than 20 running shoes from On, we can happily confirm that on average, they run true to size and fit. But, as always, there are exceptions.

On Cloudeclipse Toebox width at the big toe

Choosing the heel-to-toe drop in On shoes

If you're a beginner, it's a general recommendation to stick to the unwritten industry standard of 8-10 mm.

Heel-to-toe drop is something a lot of runners don’t know about, but it is definitely, an aspect to take into account when buying a new shoe. It’s the difference in height (in millimetres) between the heel and the forefoot.

Example of a heel striking pattern

Most running shoes put the foot in a position that is inclined forward, which means higher at the back and lower at the front. The difference in height between the two points can vary from 0 to 14 mm, and it can make your muscles, tendons, and joints work in different ways.

It’s not a rule that applies to everyone, but normally:

  • higher drops facilitate heel strike and load knees and hips more.

On Cloudsurfer 7 drop

  • lower drops help with forefoot and midfoot strike, and load ankles and calves. The Cloudventure Peak has a drop of 6 mm

On Cloud X Drop

On does not produce zero-drop running shoes, such as other brands do (take Altra, for example) and its products don’t have very low drops, as they go from 4 to 11 mm, which is a range that can suit most runners.

Want to know more about this? Read our guide on the drop.

Running in summer? Make sure your On shoe is breathable

We have found that most running shoes from On come with very well-ventilated uppers. 

In addition to trying shoes on our feet, we also used the most effective and visually striking tests to evaluate the breathability level of these shoes.

We fill shoe uppers with smoke to see how easily it escapes through the material.

We also hover the shoe's half-cut upper over the light to see the most ventilated areas.

On a 1-5 scale, where 5 is the most breathable, On running shoes got an average score of 4. This is the same as the average of running shoes from other brands. And if you're wondering what the most breathable On running shoes are...

What sets On apart from other brands?

Attention magnets

They are attention magnets with their design. This holds true for every category, whether they are for walking or playing tennis. And the same goes for their running shoes, which are stylish and perfectly suitable for casual wear.

On Cloudeclipse

Not for budget-minded runners

They are quite pricey! On has only a couple of running shoes that cost £150, in comparison to all the other models, which cost on average around £170.

Firm ride, yet responsive

On’s running shoes are usually on the firm side underfoot.

This is because the midsole is made of a denser and harder foam, that does not compress much under a runner’s weight. It doesn’t feel soft, but at the same time, it doesn’t waste as much energy as soft foam does. Instead, it gives it back to you.

Having lab-tested several hundred running shoes, we can confidently claim that the cushioning of On running shoes is 20% firmer than the average.

On Cloudstratus Midsole softness

The average durometer reading of On shoes is 29.9 HA while the average across all brands is 24.2 HA.

Oops! Less durable uppers!

One On Cloud shoe after another, we kept getting more and more disappointed with the ability of the brand's uppers to withstand abrasion.

After 12 seconds of drilling the toebox with our Dremel, it ended up with a see-through hole in most cases.

The same happened to the heel padding of On running shoes. A mere 4 seconds of Dremel touch left significant wear on these delicate uppers.

On Cloudvista Heel padding durability

On a 1-5 scale, where 5 is the most durable, very few On shoes managed to score above 2-3.

Technologies found only in On running shoes

The idea of the founder, a former professional triathlete, was to create a running shoe that was fun, and at the same time could reduce heart rates and muscle fatigue in runners. While these statements are quite bold, there are for sure some features that set On apart from other brands.

The CloudTec 

This technology consists of a particular cloud-shaped midsole, that is adaptive and can deflect with weight, both vertically and horizontally, and gives a unique feel underfoot that many runners have come to love.

Bear in mind, though, that to appreciate this technology you must like shoes that are on the firmer side of things. 


A close-up of the Cloudtec technology

The Speedboard

The CloudTec alone wouldn’t be able to recreate the feel mentioned above. It needs something to help propel the foot forward, and this is why On added a plastic layer, sitting between the midsole and the upper, that offers help with the toe-off at every step. 

The combination of the two technologies makes the shoes more responsive and faster.

3x UTMB winner wears On running shoes

Most brands have ambassadors and athletes who promote, train, and race using the brand’s gear. 

Xavier Thévenard is one of On’s athletes. His name will not sound familiar to the majority of people, but in the world of trail running and ultramarathons, he’s definitely well-known. Xavier won the 170km Ultra Trail of Mont Blanc three times, arguably the most important ultra-trail running race in Europe. He wears the Cloudultra for long distances and the Cloudvista for shorter runs.

On Cloudvista Toebox feel


Are On running shoes good for walking?

Yes. The Cloudvista is a good example as it is comfortable, feels lighter than its weight, is very breathable, can go on gravel, and looks good.

If you are not going to run at all, have a look at On’s walking shoes such as the On Cloud 5, which weighs only 8.4oz (238g), has an amazing in-shoe feel, it’s fast to slip on and off, and provides a rather good amount of cushioning and protection underfoot.

Should I get waterproof shoes?

Waterproof shoes have a membrane, usually made of Gore-Tex, that serves as a barrier against water. They can be a great choice when you are running in inclement weather and On has some models made for this, which are very easy to spot as they have “Waterproof” in the name itself.

Keep in mind that these models usually have some downsides compared to non-waterproof shoes: 

  • they are slightly heavier
  • breathability is not as good. This means that your feet might sweat more and get warmer
  • if you let your feet sink in a puddle, or water slides down your legs or trousers and gets inside the shoes, it’s very likely that it will be insanely difficult to dry.

Are there cheap On running shoes?

On running shoes are generally a bit expensive. The average price is around £170, which is higher compared to other brands’, for example Salomon (£150) or Brooks (£140). 

Runners who mean to save some money don’t have a really cheap choice within On. The lines with the lowest price tag are the Cloudrunner (£160), which sit in the stability category, and the Cloudflow (£150), for neutral feet.  

Do On shoes fit true to size? 

On running shoes usually wear true to size. In order to avoid mistakes, keep in mind that:

  • if you know you have wide feet, it’s very likely that you will need to go a half size up 
  • if you choose an On waterproof shoe, bear in mind that they tend to fit snugger, and the brand itself suggests getting a larger size (+1 US size from your regular one)
  • as a general tip, if you happen to fall between sizes, choose the larger one. To get a better idea of how it works with sizes, check out our guide on this topic: On size chart.

Are On shoes sustainable?

Yes. In recent years running brands have started making an effort to reduce their impact on the planet. This comes in various forms, such as, for example, reducing the amount of material used to create a shoe, or by using recycled parts, and so forth. 

In order to find new ways to contribute to the environment, On worked on different projects, Here are some of them.


This is a subscription service in which runners, instead of throwing away their On shoes, can return them to the company and get a new pair. This way On can recycle the old shoes and with them they make new ones. 


Another interesting way in which On limits the impact on the planet is by using a foam that is made with carbon emissions. This is made possible through a process that captures industrial carbon emissions and transforms them into liquid ethanol, which is itself turned into EVA, a widely-used material for creating midsoles.
