Two stars for obviously warm, well-made slippers. BUT, they are just too snug. I always wear a 9 and after reading the reviews, I ordered a size up. Even in a 10, my big toe is pushing right up at the tip! I am convinced this is due to an excess of padding inside the slipper -- there must be at least an inch. When measured sole to sole against my beloved, similarly styled, 20-year-old but falling apart sheepskin slippers, these 10s are actually much longer. So the shoe "last" may be a 10, but inside, it's not even a 9.  Do I want to exchange for an 11 and lurch about in slippers (flippers?)  that on the outside, are two sizes too big? I think not. If anyone has found that they loosen noticeably after wear, I would like to hear about it. Otherwise will be sadly returning them.
