These are opera slippers. I'm on my third pair and I ask for some every year for Christmas. My first pair belonged to my Dad and they came to me brand-new, still in the box, when he died. I was tired of ruining socks just padding around the house and socks alone weren't enough to keep my feet warm, so I started wearing his slippers. Oh the warmth, the comfort, and the impressive good looks. I always feel cultured just bumming around the house in them. They look like the kind of thing that Sherlock Holmes might have worn as he and Dr. Watson lounged around their Baker Street flat. If you don't own a pair, I would highly recommend them.
