I read a lot of the reviews prior to purchasing these slippers, and the biggest concern I had was buying the right size. Some said to buy them a few sizes bigger, some said they bought their normal size and they fit. So, I decided to comprimise and bought 10's when I normally wear a size 9 1/2. When I first put them on I was worried. They were a little tight. HOWEVER, after wearing them for just one day I found that the sheepskin lining eventually conformed perfectly to my foot. If I had gone 2 sizes bigger I would be swimming in these things to the point that they would be unwearable, so don't do that!!! You can get your normal size, or order the next 1/2 size up and you'll be very happy with these. You just have to break them in a little. Sturdy build and super-comfortable to wear.
