I have bought a couple of pairs of CloudFlows and I am so happy with them because of how comfortable they are. I suffered a sever car accident in which I broke both my Thigh bones (Femurs), my left Shin Bones (Tibia and Fibula) in 6 places, my Back in 2 places, and dislocated and chipped my Right Knee (Platella) and to date these are the Only Shoes that I can Walk In or Run slowly in without getting bad pain in my legs or my back.
They didn't take any time to break in and were so comfortable from day 1, not like other shoes i had tried. I would recommend these Cloud Shoes to anyone who really wants a superior shoe, whether its for Walking, Running or as all day shoes which i use them for.
The workmanship is absolutely first class and just like Swiss Watches these Swiss Shoes are everything other reviewers say they are.
Regarding sizes, I went up a half size from my ASICS of US12.5 (47.5) to US 13 (48 EU) from my normal shoes because they are a narrower type of shoe than others and that extra half size just gave me the right amount room to make the shoe so comfortable. I know On recommends going a half size down on ASICS, but I found that size to be a bit to small for me, but other people may not need to go up a half size if you already have a narrow foot.
If you're not sure whether to buy some, I would take the plunge and I'm pretty sure you will be very happy with them and the service and help I got from On was excellent.
Congratulations to all On Founders and their Team on really delivering on their amazing dream and we Thank You from the bottom of our hearts.
