Faux leather chain heels

These faux leather high heels feature a strappy front with gold chain link details Man Made Materials. Lightly Padded Footbed. Zipper Back Closure. Heel Height: 4.5" These were purchased as a final sale item and unfortunately fit me too big. I just received them in the mail and tried them on, took me less than a minute to know they were too big for me! They are a size 8.5 but feel like they fit at least like a 9.5!
