I have 5 other pairs of fit flops and these are sized more narrow/smaller. I was ordering these to replace my Gogh clogs that I have had for a year but these are more narrow and shorter than the other clog style so they are quite a bit tighter on my toes.  the fur is very cozy and warm but not thick enough to contribute to the size issue. I recommend you size up if you want to wear socks or if you have wide feet.
