Comfortable high quality shoe
First time purchase of ON shoes for me. This shoe is extremely well made and comfortable. I wear a size 9, which I ordered, and the fit is perfect. I alternate this shoe with Brooks Ghost. This shoe is softer feeling vs the Brooks but equally as stable. I find myself wearing this shoe throughout the day because it is so comfortable. Also excellent color combination.

Best shoes I have ever owned
On line order was smooth. Quick shipping with great communication.


Great workout shoe!
The ON Cloudflow is my go to shoe for any kind of workout. They're light and response and make for a faster turnover and a smooth gait cycle. Coupled with the speedboard, they really do make you feel faster! I was unable to wear the previous model because it would cut into my ankle bone, but they has been fixed with this newest model.
