Although the positive reviews and listed calf circumference of 13" were encouraging, these boots did not live up to their hype. My true size 6 felt a half-size too large. The circumference was about 14" and the buckles were not useful in adjusting the calf size significantly. Perhaps a size 5 would be a better fit, but I'm not crazy enough about the style to order it again. At this price point, I expect a great fit. Sorry for the terrible photo! I will try to find a spot with better light.
