PRADA SANDLES - silver, size 7.5, platform wedges

Hi!! I bought these sandles from a vintage store while in Milan, Italy. I was told they are real but I didnt get them authenticated. They were in good shape when I bought them, but when I wore them the soles started breaking off (and part of the Prada branding on the bottom of the sole). I took them to a shoe cobbler here and he said it would be 30 dollars to fix them - I just don’t want the project. Price negotiable - message with questions!!!
