Coach metallic pink flats - would fit size 10

I was so excited to find pink flats that would match one of my favourite skirts but alas, although these are marked as a size 8.5 they are not at all true to size. They measure about 10 3/8" long and would fit a size 10. They are really pretty with cut-outs all over, made out of a thin metallic material, not jelly or leather as far as I can tell. Excellent used condition.
