Thanks to all of the reviewers before me, I ordered a full size up (1/2 would have been sufficient, but now I can wear my beloved thick wool socks with them too!). I've been searching for 2 years for gray leather (not suede) boots, so I had to have these. They're incredibly comfortable and easy to walk in for a heel this high. I love, love, love them!!  If you like the look of them, take the chance, order up and walk on. You won't regret it.
