I have had a pair of these slippers in the past; having gotten them in a department store many years ago. It is the most comfortable slipper that I have worn, and I wore them so much that they literally fell apart. Even the size had worn off the sole. When I saw these at Amazon, I rushed to get another pair. It did not take long for them to get to me. However, they did not fit. I wear a size 8 shoe,so I got the size 7-8 Med. They run small and I am not able to wear them. This was rather disappointing to me. I suggest getting the next size up, unless you wear a 7. I think you will be fine, if that is the case. To make it worse, due to being busy, I did not get them returned on time, so I am stuck with a pair of slippers that I cannot wear. Oh well...
