Did not live up to the hype

Nate L 4 months ago Verified Purchase

I bought this shoe as a replacement to my Nike AlphaFlys and I was not all that impressed. It is a great shoe but for the $300 price tag it is not on the same level as the AlphaFlys. It doesnt have the same kind of reponse and for say $200 maybe this shoe would be worth the squeeze. I returned my pair and will stick with the AlphaFlys.

Worth the hype

I explored every other supershoe on the market currently trying to find something that I found perfect. The CB echo 3 checked nearly every box. It is firm which I love. The shoe itself provides a very snappy underfoot feel much more than any other supershoe on the market. The vaporfly 3 hoka carbon and rocket new balance and a few other of the well known plated supershoes were just too squishy for a fast race and workouts for me. I typically wear size 11 or 11.5 in ON shoes. I have ran in the cloudgo cloudmonster and cloudsurfer. I am a big fan of the ON brand as a whole now. I also measure in at an E midfoot which is slightly wide for men (D is standard). The fit on these in a size 11 for me is perfect it does fit snug through the midfoot being that most/all of the supershoes are narrow. I find that in this shoe I unlaced one of the middle eyelets to free up some space for my midfoot. It has great lockdown and the arch does not feel very invasive compared to shoes like the vaporfly or alphafly. I use these strangely for cross country (8k college). I find that these do operate very nicely on a cross course with mostly dirt and some grass. I live in california so any cross country course is very packed and hard. Though the shoe is intended for road use I find this carbon plated racer to be pretty useful for track sessions and cross country races as well. My two true complaints about this shoe are that they are said to be quick to break down and with the price of $300 it is very steep. My second complaint falls into the fragile nature of the foam in the shoe. From the first day of having the shoe I was at the track doing a short workout in them. While taking off the shoes the rear heel foam tore. The separation was clean from the heel counter on the shoe. Overall the cloudboom if you can afford it is very fast and snappy. But if you want something that will last long this shoe simply is not it.

Excellent race shoe with some caveats

Great race shoes from On. I've put about 25 miles on them so far (in two 10k races and some speed workouts) Definitely encourages you to pick up your cadence. Very propulsive and feels fun to run in. Caveats: 1) The shoe runs narrow and a bit long. If you have wide feet it'll be a tight fit. I had to go down 1/2 a size because there was a lot of room in the toe box -- I have narrow feet and the shoes ended up fitting me perfectly. 2) These are VERY rigid. Much more firm/rigid than Nike Vaporfly 3s. I think if you're a forefoot or midfoot striker these could work out great for you. The shoe is super agile but I'm not sure I would take them past anything past the 10k or half marathon distance. This is a personal preference but as you get past half marathon distance I generally prefer a slightly softer shoe.3) Durability and price: OnRunning says these are good for about 100 miles. That's not much compared to other supershoes. I like them a lot but given the (very) high price I would be hesitant to purchase these again at full price. This is the primary reason I took one star off.
