These are the most comfortable slippers ever! They also break in very easily. I normally wear an 8.5 and sized down to 8. Fit like a glove after a couple of weeks. Keep in mind that these slippers are better worn indoors (carpet and wood floor) due to the leather bottom.
I purchased these for my boyfriend for christmas. He LOVES them. So far they are a great balance of comfort (shearling is unbeatable) and durability (He even walked for a mile in them on pavement). We have hardwood floors, and I was concerned they would be too slippery, but they are just perfect.
I bought a pair of these several years ago and enjoy them as much today as when I first got them. They fit well and are beyond comfortable. They are also substantial enough for a quick trip outside if necessary.
