Vintage Burlesque Rhinestone heels Size 9

These are beautiful heels but are admittedly difficult to walk in. Would make a great burlesque shoe if a strap was added or is beautiful just for decoration. I am guessing these are from the 1980’s. There are a few rhinestones missing. I got these at a vintage boutique in Brooklyn for $120. They say Size 41 on them but I can’t imagine that these are actually a size 11 because I wear a size 8 1/2/9 and they are just a tiny bit big on me. Might be best for a size 9/9.5
