Isabel Marant Rio chain sandals

Nude leather Isabel marant sandals with chains. 5" heel. Worn a few times. Size 40 and slightly too big for me (I wear a 9 so in my opinion these are true to size, best fit for a size 9.5 or 10) zips up back. Also, the stitching on the inside of one of the toe straps has come loose, does not affect wear. Offers welcome!
