On Cloud vs Altra Running Shoes: Which Is Best For You?

Comparing On Cloud vs Altra running shoes is one of the more challenging comparisons I’ve done because the shoes feel, fit and function so differently. Yet, the one thing they have in common is how unique and recognizable both are!

With each brand boasting its own unique set of features and philosophies, the discerning runner faces a challenge in selecting the ideal footwear for their training.

As the miles pile up and the body lets us know what is working (and not), runners are increasingly seeking footwear that aligns with their biomechanics, preferences, and goals. Altra and On Cloud have answered this call with distinct approaches, making it all the more essential to understand their origins, technologies, and performance attributes.

You’ll see I have tested a lot of these shoes and like both brands, but have some bias based on what feels good to me! So I definitely went in search of other opinions to round it out.

Altra Vs On Cloud Key Differences

On Cloud and Altra offer similar features and models for all kinds of runners, from the new runner to Ultramarathoner to the flat-footed or high-arched. And of course fans of each brand will tell you why theirs is superior! But we’re going to look at the details and the shoes so you can choose.

Interestingly, Altra first became popular with Ultrarunners and has since moved in the to main stream of running.

It feels like On took hold in the triathlon market first and then quickly moved mainstream running.

I break down the differences in more detail below, but here’s a quick overview:

Altra Running Shoes

• Zero drop running shoe with cushion (no change from heel to toe)
• Wider toebox than any traditional running shoe
• Focused on improving key styles, rather than adding more styles
• Has some clothing, but primary focus is running, trail and hiking shoes

I’ve a tested and written in depth about Altra Running Shoe models, if you want more details.

On Running Shoes

• More narrow fit in older styles, some newer styles have a wider forefoot
• Recognizable sole with the pods
• Claims their CloudTec sole reduces muscle fatigue and lowers HR
• Focus on improving speed off ground and reducing impact
• Mostly running shoes, but has incredible running jackets, pants, etc as well

I’ve worn both brands and will add some personal thoughts, along with links to detailed reviews. And remember it’s important to rotate running shoes, so you might want a shoe from multiple different brands.

Altra Vs On Cloud Running Shoes

Now that you know more about each brand, let’s look at their top models in each of the main categories. There’s no winner declared here because all are great shoes, it’s just about which one is best for your foot.

With each of these, they are the top models so numbers are constantly changing as they make a little upgrade, but On doesn’t keep adding numbers to the shoe name like most brands doe.

Stability Running Shoe

👉Cloudflyer 5

The On Cloudflyer 5 is a plush running shoe with enhanced stability.

The parts beneath the shoe are wider than in previous models, and they’re designed to aid limit inward rotation, making the Cloudflyer ideal for persons with flexible arches, overpronation, or who want a little extra support.

For even more support, the latest version also has a molded sockliner and a heel counter on the outside. We really liked this addition to the shoe and it’s a bonus if you’re someone that is on their feet all day.

One of the biggest changes is the removal of the speedboard polymer plate in the midsole. On decided to do away with this to help provide that plush feel.

Unfortunately, we just don’t agree with it being plush… maybe slightly softer than the 4.  If you liked the Cloudflyer 4, chances are you’ll still be a fan of this one.

Just like the On website describes, the Cloudflyer 5 gives a “foot-hugging feel” straight out of the box.

• • Weight: 8.8 oz women’s, 10.6 oz men’s
  • Heel drop: 9mm
  • Available in 5 colors
  • Available from On Running for $170

👉Altra Provision

I am NOT someone who runs in stability shoes and yet I have really enjoyed these. They absolutely do not over correct and they are much softer than many of the stability shoes I’ve tested in the past.

I’m guessing part of the reason I liked them was a nice amount of cushion (not overly plush) and they don’t have that tale tell hardness found in a lot of stability shoes.

Women’s shoe is 8.2 oz, so also lighter than some stability shoes and as with all of their shoes a zero drop.

I also like the design of the bottom of the shoe. It provides some good drip so I could take it out on some low tech trails or days where I’m hitting both pavement and trail.

• Weight:10.1 oz. Men’s, 8.3 oz. Women’s
• Heel drop: Zero drop model
• Available in 7 colors
• Not available in wide
• Available from altrarunning.com for $140

Neutral Running Shoe

👉On Cloudsurfer

This latest shoe combines soft, cushioned foam in the midsole, a redesigned upper and a firm rubber outsole. I was pleasantly surprised with how comfortable the footbed felt the first time I tried these on, and that had me constantly coming back for more.

Cloudsurfer 2 is a moderate cushioned, lower stack height, running shoe for shorter easy runs that’s also high on our list of great walking shoes.For a daily trainer, these have the right amount of energy return and cushion while feeling breathable and secure on your feet. The cushioned midsole of these shoes isn’t overly plush, which does feel like a departure from prior Cloudsurfer models. The changes to this shoe’s midsole still feel extremely comfortable.

At 9oz, the Cloudsurfer 2 is lightweight but feels supportive enough to protect you through a variety of runs. It balances performance with weight in a way that makes this a reliable, smooth trainer.

• Weight: 7.9 oz women’s, 9.2 oz men’s
• Heel drop: 9mm
• Available in 4 colors
• Available at On Running for $160
• Read our full review of the On Cloudsurfer 2 here >>

👉Altra Escalante

As their go to every day shoe, this is one I’m often pointed to by Altra lovers as a favorite. The Altra Escalante is a popular running shoe that has gained a loyal following among runners due to its lightweight design, comfortable fit, and responsive cushioning.

It’s just 7.7 oz, which is much lighter than many shoes and it still has cushion. Definitely not as soft as the Torin or Paradigm, for me it’s slightly too firm. And yet, that is exactly what others love about the ability to feel more of the ground.

The shoe’s zero-drop platform and wide toe box can help to improve posture and reduce strain on the feet, ankles, and knees. Additionally, the cushioning provided by the midsole foam can help to absorb shock and reduce fatigue, making it easier to stay focused and productive throughout the day.

I’m a fan of styles like Kinvara that are a minimal neutral shoe and there are very much in line with that.

• Weight: 5 oz. Men’s, 6.9 oz. Women’s
• Heel drop: Zero drop model
• Available in 12 colors
• Not available in wide
• Also comes in a racer style that’s even more minimal
• Available now from altrarunning.com for $130

Cushioned Running Shoe

👉On Cloudmonster

I really enjoyed my first run in these shoes and have continued to use them in my rotation for over a year now. It’s no where near as firm as other On shoes, but it’s in no way the plush style of a Altra Torrin.

The Torrin is definitely that softer cushion. For On the cushion is more about the absorbing of impact, rather than what you might think of as traditional cushion. That’s not a bad thing, just different expectations.

This absolutely felt like the most cushioned On running shoe I’ve tested. Making it a good daily easy run trainer. I’ve put in a lot of miles on it and gifted my husband a pair because I thought it was that sweet spot of cushion and support for his flat feet.

**Note this will be getting an update with some new 2025 shoes! Or you could checkout the On Cloudeclipse which is a very cushioned shoe available now.

The Cloudmonster is a lightweight, robust, and temperature-resistant shoe that will maximize your running performance.

• Weight: 8.11 oz women’s, 9.70 oz men’s
• Heel Drop: 6mm
• Available in 2 colors
• Available at On Running retail stores for $170
• Read my full review of the On Cloud Monster

Note this is not the On Cloudmonster 2, which we also reviewed and do not recommend.

👉Altra Torin 8

Technically the Altra Paradigm designed with Kara Goucher is their max cushion shoe at 30mm stack height, but it’s also a stability model. And I wanted to make sure to give you another neutral shoe for long runs.

The 8 has a great padded tongue and heel collar. I can see why this is their most popular model. It absolutely has a great amount of cushion and overall just feels nice. If you’ve been thinking about dabbling with Zero Drop, I’d start here.

The cushion felt very similar to the Paradigm, maybe just slightly less.

• Weight: 10.15 oz men’s, 8.4 oz women’s
• Heel drop: zero drop
• Stack height: 30 mm
• 7 colors
• Wide only available in black/white
• Available at Altra Running and retail stores for $150

Carbon Fiber Plate Shoes

Are they cool new technology, yes.

Do they last as long as your other shoes, nope.

So if you want to test these out use them for speed work and then race day!

👉Altra Vanish Carbon

Altra’s Vanish Carbon 2 is the latest addition to their line of performance running shoes and has already generated significant buzz among runners and industry experts alike.

They made 17 versions before actually releasing the shoe!

The Vanish Carbon’s upper is made from a breathable mesh material, which provides ventilation and allows the foot to flex and move naturally. The shoe also incorporates Altra’s FootShape™ toe box, which allows for proper alignment and balance, reducing the risk of injuries.

The midsole is constructed from Altra’s Quantic™ foam, which provides a balance of cushioning and energy return for a comfortable and responsive ride. Additionally, the outsole features a durable rubber compound that provides excellent traction on a variety of surfaces.

• 0 mm heel drop
• 6.2 oz women’s, 7.3 oz men’s

Watch my detailed video on how Carbon Fiber Shoes work.

👉On Cloudboom Strike

After seeing Helen Obiri win Boston, a lot of runners stood up to take notice of what On was doing with carbon fiber. It’s a very different type of shoe than Nike and for a lot of runners, that’s a good thing.

Slipping on the On Cloudboom Strike, I could tell right away a lot of things had changed from the first model in 2020. Changed for the better!

• Increased cushion for distance running
• No pods along the bottom to collect rocks
• Better overall fit and foot room

This shoe has a wider fit than say the Vaporfly and even with the high stack, has a pretty stable feel. We really like the overall bounce and energy you get from this model.

Walking Shoes

I’ve often talked about the need to have different walking shoes than running shoes. However, some of my top recommendations come from these two brands and are indeed things you could run in!

Shoes that are ideal for standing around all day or walking have a little more stability and arch support.

👉Best for Standing at Work – On Cloud X 4

If you’re standing all day long you might want to consider wearing compression socks, along with finding great shoes.

The idea is something that will help you maintain good alignment so you don’t have hip, knee or back issues along with tired feet.

Street worthy style is part of their draw for many. But the real benefit comes from also feeling comfortable to wear all day long. The idea is that you could wear these to work or to workout, which means they are designed to absorb impact and keep your feet feeling good.

I have not worn this model personally! It’s one of the few not tested. But have asked a number of folks who tried it out for thoughts and many said it was the wear it everywhere shoe!

• Heel Drop: 6.7 mm heel drop
• Weight: 8.90 oz for women, 10.1 oz for men
• Available in 4 colors
• Not available in wide
• Available at On.com for $150

👉Altra Experience Flow 2

If you’re not ready to fully commit to a zero-drop running shoe, the Altra Experience Flow 2 is the perfect in-between.

Unlike most of their shoes, the Experience line has a 4 mm heel drop. If you’re curious about zero-drop shoes, we’re recommending this as a great option to ease your way down.

The feel underfoot as a nice blend of comfort and protection. It’s not firm like most Altra shoes, but not super plush like a pair of New Balance or Hokas.

Altra updated the midsole with the all-new EGO P35 foam. It’s super lightweight with just the right amount of cushion so that your feet feel just as good at the end of a run as they do at the beginning.

The Altra Experience Flow 2 is a great daily trainer, but also feels fabulous as a walking shoe and for standing around.

• Heel toe drop: 4 mm
• Weight: 7.5 oz women’s,  8.15 oz men’s
• Stack:  26mm/30mm
• Available in 8 colors
• Not Available in Wide
• Available from Altra.com for $140

Trail Running Shoes

I admit that my experience running in On shoes for the trails is limited because I had enough issues with rocks in the road shoes. However, I think the Cloudultra fixes this issue based on all the feedback I’ve received!

👉Altra Lone Peak

The Altra Lone Peak has an EGO midsole that gives you the right amount of cushioning for the trails while still letting you feel the ground. It’s one that many Boulder, CO runners really love.

The MaxTrac outsole provides plenty of grip and traction as you run over uneven and slippery terrain.

Plus, Altra’s signature features were designed specifically for trail running. The zero-drop cushioning improves ground feel when running over roots and rocks, and the FootShape toe box allows your toes to splay for better balance on uneven terrain.

It’s a great pick for the trail with balanced cushioning, excellent grip on loose rock and mud, and a super comfortable fit for wide feet!

This is one of the few models they’ve made it up to version 9, which says a lot. It means runners are repeatedly asking for the shoe and love it (otherwise they stop making it!).

Somehow the shoe manages to be breathable and quick drying, while still having the structure you need for the trails and the sturdiness provided from the outsole and rock plate to keep your feet happy on more technical trails.

• Weight: 11.15 oz Men’s, 9.3 oz Women’s
• Heel drop: 0mm
• Stack Height: 25mm
• 7 colors
• Available in wide for some colors
• Available on altrarunning.com for $140
• Read our full review of the Altra Lone Peak 9 here >>

👉Cloudultra 3

This still isn’t a hyper-aggressive trail shoe, but it stays true to its reputation as a long-haul partner. It still balances cushioning and stability without losing its smooth, easy ride.

The midsole is where you’ll feel the biggest change. On added a dual-layer Helion HF hyper foam that feels a little softer without losing the snappy responsiveness. I think it’s a game-changer foam.

It’s considered a plush cushion, but it isn’t too soft, and it protects the foot while still having a high energy return. It’s a bit of a unicorn in how it does it all.

The outsole also received a welcome upgrade. On ditched the old square lugs in favor of the popular chevron pattern, which gives the grip a noticeably more secure feel on loose dirt and rocks.

Making it feel more capable on technical trails.

• Weight: 8.28 oz Women’s, 10.4 oz Men’s
• Heel Drop: 6 mm
• Available in 4 colors
• Not available in wide
• Available on On.com for $190

Which is Better On Cloud or Altra Running Shoes?

There is no “better” option here. Just the shoe that is going to fit your foot the best and help you run without injury. Based on the general differences above you can see that Altra can be great for really spreading out the toes, which gives you more ground feel and power in your push off.

While On Running may provide you with more of that spring (and style) that you’d like.

On Running vs Altra Feature Comparison

Both brands are newer to the market compared to many, but have quickly gained avid fans.

The differences in these two lines is significant to me from fit, to feel, to function.

While both provide various levels of cushion and trail shoes, On Cloud is going to offer more traditional versions of things like a stability or motion control shoe and does not currently offer a zero drop model.

The following breaks down each shoe based on the components buyers need to consider when purchasing a running shoe.

It’s gonna get a little TECHY…so you can just skip on down to the specific model comparison if you want, but personally if I’m shelling out $150 for shoes, I kinda want to know why.

Durability 

The lifespan of shoes from both companies is fairly comparable.

• On recommends swapping out for new shoes every 310 to 465 miles, a bit more specific than most brands.
• Altra shoes have a life expectancy ranging from 300 to 600 miles. I’ve heard many runners say they feel like they last longer.

Determining when to replace running shoes, of course, all depends on your gait, weight, and whether you run mostly on trail or road.

Shoe Fit

Cloud shoes are a little hard for me to describe because I think they’ve changed over the last few years and are different with each model that I’ve tested.

While the length runs true to size, I would say some are a narrow fit and some have a little more room in the toebox.

I would not consider any of the On Cloud’s a wide shoe (except the one’s made in wide width). But looking at these photos they may appear wide, which I think is due to the styling.

Altra stands apart when it comes to fit.

• Larger toebox for a shoe more shaped like your foot.
• Zero drop shoe means a smaller heel.
• A lot of focus on how gender changes fit.
• Some have noted they feel the size runs small in length, but that is not what I’ve found.

Cushioning

On uses CloudTec technology which is entirely what makes their shoe look and feel different. They have little open pockets on the bottom of the shoe that compress with each step to absorb impact and in their words feel like a cloud.

I would say they are cushioned, but not plush.

Altra focuses on a technology of Balanced Cushioning with Quantic. Thus providing that even level of cushion from the heel to toe of the shoe and keeping the zero drop. I would say they have greatly improved in this area over the years and now have some truly great cushioned shoes.

Stability

On goes against the grain of most stability shoes and works with your foots motion rather than trying to stop it. I appreciate this as it’s one of the many reasons I steer folks away from most stability shoes.

Instead, they changed the shape and location of some of the pieces under the arch of the foot which allows all of your muscles to continue firing, but slows that inward roll.

Both brands have two different categories: Neutral and Support. From testing I feel that these two brands don’t overdo the support as many shoes used to. Instead, they are really focused on ensuring the shoe provides a little guidance, but doesn’t overcorrect or lead to any muscle weakness.

Whether that’s a little bit more support in the arch or through the midline of the foot it helps hips, knees, and joints to move naturally, offering support when needed. Neutral runners may only require them to kick in when their stride is off.

Read more on different types of running shoes to understand if you need stability >>

Affordability

The prices between the two brands are fairly comparable.

• On prices range between $130 to $170
• Altra’s start at a at $120 to $180.

Specialty items with more features (like carbon plates) will increase price.

You’ll notice that every brand offers a range and this is indeed due to a difference in technology and where they sell the shoe. They know that the big box store can sell the shoe with less in it, while the local running store needs to be best for dedicated runners.

More About On Cloud Running

On started in 2010 in Switzerland, when yet again another runner thought “I could do this better.”

This time it was three retired professional athletes, who decided there needed to be a shoe that had more firmness to create that bounce off the ground, along with cushion.

They went from their first prototype in January 2010, to having it sold in stories by June 2010! How insane is that timeline?!

By 2014 and 2015 professional athletes were wearing the shoes and winning races, creating even more buzz about these unique looking shoes. They’ve done a great job of keeping that Swiss engineering while also providing some much needed style to running shoes.

More About Altra

ALTER + ULTRArunning = Altra.

The name came to be from a crazy path of a young marathon runner named Golden. He started altering regular shoes to create a zero drop with cushion…it slowly became a bit of a black market thing.

People would literally buy a shoe from the running store owned by his family and then ask him to rip it up and remake it as  zero drop footwear!

Suddenly, he realized they were doing this for nearly a 1,000 people. Maybe making a shoe would just be easier.

Thus, in 2009 the brand was born.

Your gait and feet will likely change over time and you may need to change shoes.

This is also why I recommend rotating through several pairs of shoes at once.

And remember, just because these are two of the most well known brands on the market, there are still plenty of other shoe brands to select from if neither an On shoe nor Altra has the right sneakers for you.

Keep in mind that shoe design can change, even with the same model, so always assess how the shoe fits every time you replace a pair.
