I love these boots even though the footbed is slightly uncomfortable and the calf is very wide even on the narrow model (I double checked the model thinking maybe I got the ones for fat calves).  In a size 8 it measures 15 inches around the top opening.  I'm super athletic and want a tight fitting boot...I really thought these would work and I may still keep them if I can't find anything that fits better.  5'6", 125, athletic, size 8 shoe
