SOLD**Givenchy navy suede ankle boots

Size 37 givenchy navy suede ankle boots with straps. I bought them at a local consignment store for $350 to give to my sister for Christmas but ended up doing something else and they are not my size. As far as authenticity I'm assuming this store wouldn't sell a fake BUT I'm def not trying to scam anyone so if you know of a way to be sure they are real I'd be glad to check before you buy. The soles looked like they were never worn but the heels scuffed a bit rubbing together in the box etc.
