Prada leather 3" heels

I bought these Prada heels like new in 2003 and have worn them 4 times in the last 20 years. There are small scuffs on the heels (see photos) and the soles are barely worn. The button holes works - the button is real and usable and they are 20s inspired shoes. They are a size 39 - so about an 8.5 or 9. I have wide feet and they fit me and I'm about a size 9. The patent leather colour is almost black Brown and they're pretty comfortable. I love these shoes but as I've gotten older, I can't wear heels anymore. :(
