These slippers are cute and warm.  But they have absolutely NO support.  So your feet slop all over the place and they really aren't comfortable.  I really hate them.  I purchased them in two different sizes / colors.  Smaller size is way tight, larger size is hugely loose.  Instead of these slippers, I'd suggest the Acorn Chinchilla Collar slippers, which fit true to size, have a TON of comfy support and are very warm.
