I normally wear a 6.5-7 and I took the advice of other reviewers and went with a 6.5.. I wish I had ordered up; it was a little narrow so the fit was a little tighter than snug. There was also no arch support, so I should have gone for an even bigger size *(maybe 7.5) and added arch support. The boots were also surprisingly taller than expected. I'm a short girl (5'2&#34;) and this hit me at the middle of my knee, which just looked weird. The calf was also pretty wide. I have pretty normal calves and they were just a little too roomy for my tastes. Had to return, which is a shame because the materials and craftmanship of the boot are really nice.
