Zara Red Shiny Sandal Heels, EU39/about 8.5 US

I loved these so much I took a chance on them fitting but alas, an EU 39 will not become a US 7 no matter how much I will it to be so. I believe 39 is an 8.5 but please check. These seem to be lightly scuffed on the back (white marks), but this could actually be part of the patina. They otherwise are unworn.
