I really like these slippers and they are very nice quality...I have owned them for close to a year now!  I am a size 7 and I ordered the 6 1/2-7 1/2 size.  I found they fit at first but have stretched out and are now too loose for me to wear without socks (and with socks they are too warm).  They are great but they do stretch and become somewhat large over time.
