Comments: I've been through numerous pairs of Cloudracers, and I couldn't be happier. The shoe is not quite as light as some other brands of racers, but I use it mostly as a medium-to-long distance trainer. It has a nice snug feel, but gives me more room in the toe box than traditional racers. I've used this shoe for my last two marathons, and it has felt great both times. The clouds have held up well & I managed to get 455 miles out of my most recent pair. I would definitely recommend this shoe to anyone.

Comments: I am in love with these shoes. Very well constructed, feels extremely light and at the same time provides great protection. I am a 6' 210lb guy and haven't had any issue while running on this shoes. I have used them in 5k and 10k races having excellent results. Definitively a shoe you must have in your running gadget arsenal.

Comments: Im a huge fan of these shoes. Its fast, lightweight, durable, comfortable with my Sofsole fit insole. Coming from Nike shoes I'm a size 12 and the size 12 On fits me perfect. My only gripe is the mesh part on the forefoot was so thin after only a few hundred miles it started to shoe holes... I hope to be back in these shoes only if this issue has been addressed.

Comments: KAILUA-KONA, Hawaii -- Belgium's Frederik Van Lierde won the Ironman World Championship. In muggy, but calm conditions, the 34-year-old Van Lierde finished the 2.4-mile ocean swim, 112-mile bike ride through lava fields and marathon run in 8 hours, 12 minutes, 29 seconds to become the second Belgian winner. It was the eighth-fastest time in the 35-year history of the event. These were the ON Cloudracer shoes worn in that race.

Comments: I have found the Cloudracers to be an excellent shoe. Last year, I ran in the Asics Gel-Neo33 as my long distance shoe. (I run in vibrams for distances less than 8 miles.) While the Gel- Neo's were good, I was never in love with the shoe. After my last marathon, I switched to the Cloudracers to give them a try. I immediately loved them. I had run in Newton's last year as well. However, as others have mentioned, I found them to be too unstable. I never felt that way with the Cloudracers. I have been looking at other brands for a marathon distance shoe, but I don't believe anyone else has come up with the magic combination of cushion and minimalism that these shoes provide. As to the heat of the shoe, I have switched to an ultra thin/lightweight sock, and they have been nothing but comfortable.

Comments: Cushioned responsiveness. Once thought to be mutually exclusive; now inexorably linked in On's Cloudracer. Not sure what magic they've used to pull it off, but somehow it works; at least for me. I've hesitated writing this review for some time. Never one to identify any one shoe as perfect, my review is largely motivated by the fact that I've come back to this pair time and time again for their unique feel. I find the outersole to be quite unique and lives up to the claim of a soft, smooth landing (claiming to be the first to address horizontal impact/shearing) whilst providing for a relatively firm and stable push-off (something I think the Newton line of shoes fails miserably at). At no time have I ever been able to drive hard into a turn/corner without the forefoot of a Newton shoe feeling increasingly unstable. In this regard, I think the On outsole tech (extending the entire width of the shoe) picks up where Newton left off. I tend to stay clear of running shoes that don't have full ground contact at mid-stance as these shoes inhibit a good midfoot landing IMO (some of my favs are the New Balance 1400, 1600, K-Swiss K-Ruuz, etc.). Oddly enough, however, the Cloudracer feels quite natural in this regard. Again, not sure how they managed it but they did (especially considering the significant amount of midsole missing between the heel and forefoot areas of the outersole). It feels quite stable, in fact, and I don't find myself searching for a sweet spot with every landing. I really like the feeling of the shoe; not overly soft yet surprisingly responsive. I found the fit a bit long (I sized down 1/2 size) and I believe Running Warehouse recommends doing this for the other models in their line-up. I like the midfoot wrap and I've had no issues with the laces (you get two different colors). While I don't find the forefoot all that wide or anatomical; for me, at least, it's wide enough, plenty of wiggle room. The shoes seem to be wearing quite well, too (I've accrued close to 300 miles in my pair without them appearing to be too worse for wear) The biggest area of concern I have is one of breathability. The upper is quite thin but I don't find the material to be really all that breathable. It's almost plastic. Admittedly, I've run in some of the most humid conditions (Tampa, Florida in August for example) but I invariably return with shoes full of sweat and quite heavy. I think On needs to address their material choices and go with something more hydrophobic (like K-Swiss; Ion-Mask, for example). Otherwise, great shoe in my line-up and I'll most likely purchase a second pair soon.

Comments: These shoes are very well constructed and shows quality in it's materials. Much better than Newton in that aspect. The feel and ride is comfortable and a bit stiff but responsive. They are ventilated enough for hot days. My only complain is weight; I would've liked to see a lighter shoe. In summary, i believe it's a good lightweight trainer with a comfortable and responsive ride.
