This slipper is really cute.  It is also sturdy, well-made, and warm.  It fits true to size; I wear a 9 and the length fits perfectly.
It fit very well at first, but stretched out so much after a week I could only wear it with a thick wool sock, which is okay since I have them for winter.  Just know that it stretches.
My only real complaint is that I have Rheumatoid arthritis and Lupus, which affects my feet a  lot.  This slipper does not have enough padding for someone with achey feet.  It would probably be comfortable if you don't have sore feet issues,as the bed of the slipper is sculpted nicely, as well as the overall shape.
Were it not for the stretching issue and padding, I would have given this a 5.
