At first I wasn't used to the thick cushiony sole, but gradually I have found that these shoes are amazingly comfortable.  The fit is snug and secure without pinching. Most slides tend to be loose and I have found myself stumbling on my stairs.. but I never have a problem with these sandals coming off or shifting.  If you are between sizes 7.5 and 8 (as I am) go for the size 8.  Fit is perfect!
