Reading many other customer reviews b4 I purchased these boots, I ordered down one full size from my regular size.  It still was waay too large w/thick socks on.  A few other reviewers mentioned that they ordered their regular size or a half a size down. Inconsistent sizing, it seems.
I had to return them and am afeared to order another pair 2 sizes down, hoping they will fit. Don't want to send a 2nd pair back.
Good looking boot and felt comfy inside though.
