Stuart Weitzman 50/50 over-the-knee leather boots

LOVE. THESE. BOOTS. 2nd pair I've owned bc I wore the first out. Unfortunately, these fit small for some reason. I can't find the size anywhere on the boot but I'm a size 7, and going to list these for a size 6 - 6.5. I could get in them, but they were uncomfortable for me to wear bc too too tight. Would be better for someone who goes 6 to 6.5, considering socks.
