I have some Stuart Weizmann over the knee heeled boots in a 6 They have always been way to big but I’ve worn thick socks and an insole for if I ever wear them. I then brought a pair of the leather non heeled boots in a size 4.5 perfect fit for me. I’ve found a pair of heeled boots in a sale in size 5 but there to small just a little tight I can wear them with tights just not socks I’m usually a size 5 or 6 baffled how they don’t fit I can’t return these either any way I can stretch them.
