Warms feet....sizing not accurate.
I got these for my partner for Christmas. They warmed his feet just fine, but unfortunately he wasn't able to wear them until I exchanged them for a larger size. Sports Unlimited made the exchange without any hassle, but I do wish my partner could have worn them on Christmas day. I don't believe the sizing chart was accurate. He wears a 10.5 shoe size and yet ended up needing the absolute largest slipper size of XXL.
