Balenciaga Black Double Buckle Slides

Balenciaga “Birkenstock” style platform sandals in black lambskin w gunmetal hardware. Guaranteed authentic! I bought these from Balenciaga myself. I wore these once and then realized they were actually too big so i couldn’t return them :’( that said they are in great condition, other than a nick in the leather on the right shoe (pictured) so the price is low bc of that (others are selling for $650+). Pretty unisex style, size EU 41 US 10 or 10.5. Open to offers!
