They run big. Size down. I wear 8.5 and 9 in on clouds and the 8.5 has plenty of room! look And feel great. Price is not what I wanted to pay lol but they were so comfortable and cute I went back the next day (after trying and saying I’m not paying that) and purchased them. Best on clouds thus far. First ones were terrible on my feet. They put more thought into comfort w this pair.

Purchased these to run a half marathon at Griffith Park in LA. I bought them the week of the race because I only did road running for training. I was nervous because there was zero break-in for the race. The shoes were great. I went with On for trail shoes because I have 2 other pairs of road shoes in my rotation and they are my favorite. I had zero blisters or foot pain post-race. I do wish there was a little more cushion, but the tread is great and provided traction on the steep trails.

I have the Cloudmonster and love them for the cushioning. I’m trying to find a hiking shoe with great traction and that much comfort and cushioning too. These Cloudultra are not as plush but still pretty comfortable. Have to return them because of sizing though. I’ve been buying men’s size 7 for the extra room in the toe box but I thought I’d try women’s 8 in these. A bit too tight in the toe box and in length, so I’m going back to men’s sizing. Not a big deal but the colour is less vibrant than the picture too.

Fit seems different. I Oder same size as my original ultras and the fit seems a little shorter, wider and less arch. The stretchy part that goes around the lower ankle that allows for slip on is completely different. I preferred the original ultra as it was better material and more comfortable.
I run 2 miles a day and I alternate between these and the all black cloudmonsters. These shoes are pretty solid and have great grip on the road and dirt. As for the comfort I give it a 8 out of 10 it doesn’t quite have the bounce I like while jogging although it does have good cushioning. I weigh 200lb btw
I have had two pair of the original version of the Cloudultra, which I used for trail running distances between 3-15 miles at a time. I mostly run on gravel roads and single-track trails, and find the Cloudultra to offer good support, cushion, and traction. I am sure I'm among the minority in disliking the extra room they added to the toe box in this version. I have narrow, low-volume feet and this shoe fits me better than other trail runners. However, with the extra room in the Couldultra 2, the fabric bunches a bit when I pull the laces tight at the front of the shoe. Still, this is the best I've found in terms of a solid trail runner that can handle the miles and terrain for narrow, low-volume feet. Shockingly, the nearly white fabric isn't showing the signs of ... MoreI have had two pair of the original version of the Cloudultra, which I used for trail running distances between 3-15 miles at a time.

These are by far probably one of my most favorite ons. I have a few pairs but these are supper soft all around. I like that the colors are a neutral gray with a very light blue undertone. They are so light that I forget that I have them on. Love them
So, my regular shoe size is 8 1/2 in most shoes.I sized up as suggested and the size 9 was a horrible fit - too large and the stability just seemed off with little arch support.I bought a size 8 1/2 and my toes were touching the end.. way too small.I had hopes as I’ve been wearing Clouultra 1 for quite some time and realized the toe heel drop was 10 mm and this was causing my feet to push forward and I was getting ingrown toenails for the last year.The cloudultra 2 has a 9mm drop but the arch support is off and I could feel tension in my arches.I’ve been wearing On’s for years..Overpriced and not the quality they used to be.In summary.. it’s “Cloud Off and Not On”
I read reviews online and ordered a half size up. These either run considerably smaller than standard size or the depth of the shoe (if that makes sense) is drastically off. My big toe was rubbing against the front and top of the shoe. They are a super cute sneaker, but something is not right with the design.
I am huge on word of mouth and heard from so many people these are a great do it all shoe for trail and long distance. They are lightweight, breathable, so comfortable out of the box, I ran a few miles my first day on them and noticed there is no break in period. I love the elastic band to keep the laces secure and the FlipRelease truly is great. I kept mine unlocked but can see great benefit to keeping it locked! I had to get my mom a pair! I have an average arch and wear 7.5 in Merrell and Salomon. I got a 7.5 in these and they were a great fit. 10 / 10 recommend.#BackcountryGearhead
