Purchased these in size 6B(M) as recommended and they are perfect. Not sure why others are indicating the size is small. They are a narrow shoe and may likely not be for those with wide feet. I put them on as soon as they arrived and are very comfortable. While my heal did hit the back lip of the shoe, after walking in them and working them in, they stretched enough that my heal no longer hits the lip. Had I ordered a 7 as others suggested, they would have been too big by a half inch at the heal. As much trouble as I have with shoes, I had to say these are really nice, perfect for spring and summer. I prefer shoes with open backs that you can slip on and glad I got these. Again, if you have wide feet and normally take a wide shoe, then maybe they are not for you unless they come in wide. Don't discourage others not to buy them. Good price and good quality.
