I ordered the next size up as well, to test to be certain,but found they were too loose on the heals. However, size runs smaller to my actual shoe size. Problem #2 was when I noticed how awful the fit seemed in my ear, I switched ear tips hoping it would fix the problem yet it didnt. And recommend to friends and family. Very versatile! I could walk all day in these shoes. After half an hour of using the device it would show on my phone as 80% and it would then go down just as fast. The only complaints I have are that I wish it had hanger ribbons (i can see this dress stretching out slowly over time on a hanger) and that its ultimately longer than Id like. However this bike rack is clearly intended to go on the back of a camper and it should be strong enough to handle some less than Interstate quality roads. I reordered another one.
