Hello! I have an awesome pair of vintage white cowboy boots. The vamp is lizard. These are Justine and the size stamp on the boot says 8.5 A however please look at my measurements as I feel they fit a normal 8 1/2 medium. I wear 8 1/2 medium and they fit me fine. Also there’s a stamp that says irregular but I’m not really sure what it is. That makes these irregular because they look fine to me. I don’t see any imperfections in the boots. They are vintage so keep that in mind but I feel that these are excellent condition for being vintage boots, especially being white ones.
