text: This shoe is very light and almost comfortable.  But I bought them for all day walking, and the other reviews are right:  they are a half size too large (my heel slips up and down when I walk).  I'd try them a half size down from what I usually wear, but I also agree with the reviews that say the height of the part over your heel is too high and rubs.  I am almost positive I would get blisters.  It might be fine for a shorter walking day, but for amusement parks not good.  These are going back unfortunately.
