Abercrombie & Fitch nude sandals shoes slide on elastic strap ( 8 or 8.5 ?)

There are no size markings on these shoes but due to measurments and someone who wears 8.5 shoes trying them on I would estimate these shoes at an 8 or 8.5. Take a look at the measurments. Also take a look, they show some wear to the soles, they have a big mark on the one side of the strap and they may have a mark or scuff here or there on the shoes, they are in good USED condition. Please ask any questions before purchasing. Thanks for looking!
