Bought a size 8 which is my usual size and it was way too small.  Returned for a size 9 and was sent a man's size 9. Returned it again for a womens size 9 and it is still too tight but I'm tired of returns and will give these to my granddaughter. I have a pair of Acorn sheepskin booties I have had for about 6 years.  The new ones are nothing compared to them.
