I wear a Dansko size 40 in their shoes but a 40 in the boot is a bit too loose for me, so that's why I gave it 4 out of 5 stars.  I think I will try to put a sheepskin insert in the footbed to tighten up the fit a bit more.  However it's a great everyday winter boot for sloppy, snowy days.  Love the look even more when you flip up the sheep skin collar around the top of the boot.  For the price, I have no complaints!
