I thought these boots would fit my 14" calves and they almost did on my right leg.  Unfortunately the left one was slightly bigger and gaped quite a bit which bothered me.  Neither boot fit as well as I had hoped in the calf, however the 9 1/2 being my regular size fit perfect foot wise.  I have wide feet so the flex in the material worked well. Unless they are snug fitting in your calf, they look baggy and cheap as the material is very thin and meant to take the shape of your calf.  Otherwise they were comfortable walking around inside and they have a nice heel height. Due to the loose and irregular fit in the calf they had to go back.
