authentic Valentino shoes in a size 8 but run small, fits more like a 7-1/2

Authentic Valentino 3 inch studded heels, used but in good condition. just had cleaned and had new sole on the bottom of shoe done. has a bit of peeling paint by the straps which once on cannot be seen. it’s a beautiful shoe but since having kids they fit a bit tight, they run small, so are more like a size 7-1/2.
