NWB Oscar de la Renta Ramona gold sling backs 37.5

Exquisite 70s/retro style Oscar de la Renta gold sling back heels (3 inches). New with box. Never worn. Unfortunately, these are too small for me (true 7.5) and would fit a 6.5 better. Runs very narrow. Just trying to make space in my closet otherwise would not be letting these go this cheap.
