These leather knee boots are sure to make an impression! They are VERY stretchy and allow for a bigger calf (my calves are 16.5" diameter and they fit me) and are very comfortable to wear! They're listed as a 37 on the sole; they seem to fit large as I'm normally a 38/Ladies 7 and they fit me well, even with a bit of room. They're about 9.5-10 inches long at the foot (above the sole).
