Black platform heels

Killer black heels. Zipper closure in back. There is no size printed on the shoe. When I bought them the sticker said Euro 38, but they were either mislabeled or run large. I usually wear an 8 or 8.5 and they're too big for me (I can only wear them with socks/inserts). Fits like a size 9. Worn twice, light scuffing in a few places.
