Ordered size 11. These shoes are not a true size 11 M. At first my feet would not fit past the forward stap. With some stretching, I was able to get my toes partially in. Then it stopped at the rear portion as it was too tight to allow my feet to enter further. With some forced stretching over several days, they fit somewhat better, however they continue to be too small and are also a bit narrow. All size 11 M shoes including slides, have allways fit. These no not fit. I would return them, but have worn them trying to stretch them and am not sure a return would be accepted. These could be very nice slides if not for the strange fit. Even the length is somewhat questionable.
