Query: not quite what I expected

These slippers do keep your feet warm but the "rubber" sole feels more like foam and is not flexible so I'm a little nervous about wearing them outside a lot because I don't think they'll hold up. Also I ordered a size 8 and received a size Large so I guess they are not really sized by 6, 7, 8, etc. They were a little big but it would cost me money to send them back and pay a restocking fee so wasn't worth sending back. I wouldn't buy these slippers again.
