These are in excellent preowned condition. I love the white stitching on the rust colored suede. I also like that they have a bit of a heel and they’re comfortable to walk in. Size 40. Euro sizing.
According to conversion charts I’ve seen, these are supposed to be an 8 1/2 in US sizing. I don’t know why it says 6 1/2 on the bottom, perhaps that’s European sizing as well. I wear an 8 1/2 and these fit just fine. Wurishofer Fussbett's women’s leather and suede sandals.
