"I really was looking forward to these boots and was excited because they were wide calf, it says the circumference is 15 1/2 with added extension and there is no way that those boots are 15 1/2 plus added extension. I have wide calf boots with a circumference of 15 3/4 that fit me either perfectly or a little to wide. These did not fit even when I opened up the extra extension. I was very disappointed and will be returning them to exchange for a pair I am sure are wide calf. Very sad these aren't truly wide calf....."
