Jimmy Choo knee high boots 7

I bought these used listed as authentic. They feel very soft on. I liked the low heel, only 2.5". However, the heel snapped so it will need to be taken to a cobbler. I'm sure its an easy fix for them and maybe add a toppy to make a new again. I cant even zip up the calves anymore. Its for the skinny leg thats for sure. Boot calves measure 6.25" flat. Size is 37.5 but fits a true 7.
