I found the sandals to be true to size except for the width. I have a very narrow foot and ordered a medium thinking it might be a little too wide but they were too narrow, even for my skinny foot. I have been wearing them around the house with sox on to stretch them a little.  overall I am happy with my purchase as they are comfortable to wear but if you have a wide foot be aware that the wide fitting may not fit you. I live in Australia and the packages I order are always promply delivered. I am very happy with the service Amazon gives.
