Boots look nice.  BEWARE ALL I READ WAS HOW TRUE TO SIZE THEY WERE ETC. My experience has been they run SMALL.  I normally wear a 7.5 at most.  I ordered an 8 medium. They are just okay. They are not a comfortable boot out of the box. I'm going to keep and try and break in.  My upper calf is about 15/1/2" these just fit. If your bigger don't get these boots. I also ordered the 9west SHIZA
Ina 71/2 that was to small. They did fit my calves but to uncomfortable to keep. I'm not going to live in these boots so they'll be okay I think.  GOOD LUCK.  I hope this helps.
