I got my On CloudUltra Pro’s a couple of weeks ago, and after hemming and hawing about not getting them in my Brannock device measured size of 12.5 I’ve accepted that going up a half size to a 13 in these $260 trail running shoes was a good choice for me. When spending hours on your feet more room is definitely better.

These new breathable uppers like the Cloudultra Pro have don’t really lend themselves to forming around your feet. But I’ve not gotten to 100 miles yet in these On shoes which are my first pair from that company, so we shall see.

Came here to say this. I was anti-on until I tried this shoe. I till think there lower end stuff is gimmicky but they high end seems worth looking at

I'm in an 11 in the Cloudultra Pro and an 11.5 in the ultra 3's. I have odd sized feet though, where I'm either between an 11 and an 11.5 and can seldom find that perfect fitting shoe (thank you Salomon s/lab Genesis). I was initially in an 11.5 in the Pro's, but was kicking so many rocks and catching my toes I had to go down a half size. I don't find that to be the case in the Cloudultra 3. I feel like the 3's have more volume in the toebox and are more spacious than the Pro's. They also feel more stable than the Pro's as well.

Long time Bushido II guy myself, actually have 2 unopened men’s size 10s in my garage if you need one 👌 The On Cloud Ultra Pro is truly unbelievable— used it to train weeks of flat road miles on a beach trip, scrambling some ridges, and have worn them for 160km without ever having to tie or adjust them over the whole endeavor. What’s more, I have one pair with 650+km and another with 500+km on them and they’re still kicking.

On Cloud UltraPro is the shoe. Gives you the boost, never comes untied, is comfy and breathable 🤌🤌

I tried the cloud ultra pro but it was too narrow for me and I don’t have particularly wide feet

I have the Cloudultra Pros. They're awesome. The midsole is extremely comfortable. The speedplate is fiberglass rather than carbon, so the propulsive effect is pretty modest, IMO. I think the La Sportiva Prodidgio Pro might be the best comp.

Ride is close - has a smoother, less aggressive ride compared to some other super shoes, similar to the Tecton X 3. I'm always surprised by my paces then I run in that shoe - just feels efficient. This has a similar kind of feel.

I was actually just walking around in them this weekend casually and it was noticeable how fresh they felt, not much if any noticeable compression.

Yes, I noticed some pinching on the lateral side - right at the edge of my foot, base of my pinky toes. The material seems to "crinkle" up at that point. I didn't notice it anywhere else across the toebox. But that spot was very noticeable. I was very concerned about it, but it was a non-issue over the 108K race. It has softened a little bit, but I still feel it - but again, it hasn't caused me any irritation or blister.

It's on par, maybe slightly better. I think the lacing here gives you a better hold around the midfoot, but the shoe overall is pretty roomy, especially in the toebox. A lot will depend on how your foot fills up the volume inside the upper.

Yes, filming one of my test/review videos. On Cloudultra Pro vs Kiprun Kipsummit Race

I do these types of runs after I've run significant amounts separately in each shoe. For example I've raced a 108K in the On shoe, so I have a pretty good handle on that one. The Kiprun shoe is newer so I'm trying to see how it compares.

The fit is very similar to the pro, moderate heel leading to a more narrow midfoot and a wide toe box. There is a nice amount of volume in the toe box as well, so it should accommodate moderately wide feet well. The ride is solid, responsive and stable with the foam being softer than past versions. I’ve enjoyed the 3s for the 30 or so miles I’ve put on them, love the pros though
