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.
