Got this slipper for my granddaughter for Christmas.  I have looked them over and they look very comfortable and warm for her feet.  I took sizing advice from her mother but they look a tad big.  We shall see.  Don't want them small but too big isn't good either, at least they are slip on style.  I'll update after she gets them.
Update:  She loved the slipper. Wears them all the time at home and brings them to Grandma's house.  And the fit was just fine.
