Black sexy knee high boots size 9.5

Super cute soft black knee-high boots with a heel, I have pretty muscular calves and these fit me. Long zipper up to the side. Really good condition, only worn a couple times. I did just notice the inside of one of the boots says 10 while the bottom of both of them say 9.5, I never noticed that they fit different so I'm guessing they are truly both just 9.5 and it was a mismark.
