This is the third pair of grey OTK boots I've ordered and they FINALLY work well with my body type! I'm more muscular so the largest part of each calf measures 15.5 inches, while my thighs and knees aren't larger than most. These fit fantastically and even work with jeans! My feet are also flipper like so some boots are too narrow but these are roomy for comfy socks in a size 9, where I'm typically and 8.5 or 9. The only reason I docked a star is because the inside zipper puckers out a bit at the ankle, but I figure any boot this style would do something similar. I'm so excited about these especially for the price :)
