CHANEL black satin bow heels sz 40 9.5

Beautiful black satin heels by CHANEL in size 40. They have been repaired by a cobbler (see bottom photo heel) but are in beautiful condition with only small scuffs on the bottom. Bought them on eBay as a sample model for $750. Selling as they are a smidge too big for me and now that I work from home I rarely dress up - sad to see these sit in my closet. I would say they fit true to 40 but are narrow. Open to offers!
