"I am 5'0" with wide calves (about 16" circumference). I ordered a 6.5 and they fit very well! My only issue with the boot is that is looks kind of bumpy on the back on my calf, which could just be me? I thought this was due to the boot being too big (I initially ordered a 7) but I guess not. Overall, it's a super cute boot and pretty comfortable! I would recommend buying grips for the bottom though as the velvety sole is slippery."
