I wear a size 8 and ordered the size 8/9 but the bedroom shoes was too short. So without a problem Amazon replaced the shoes immediately with the next bigger size--which fit just right when I first got them. Now I have been wearing them about 3 months and they have stretched out so much that they are loose on my foot. I bought these particular shoes because they are opened toed and I have very sensitive toes that can't stand to have anything touching them--this shoe is perfect for my toes. I still wear these shoes but wished that they were not so loose now because they want to come off my foot, especially when walking up and down stairs. So beware that the width does stretch after wearing them.
