These new sandals were given to me as gift, I don't know the authenticity, and there is no serial number. I never wore these because they were big for me, and I am size 6. Please make sure you check each photo for measures and condition. Smoke free/ pet free home. Thanks for checking my closet! **REASONABLE OFFERS ARE WELCOME** **THE SANDALS ARE FINAL SALE, NO RETURNS SINCE I AM ADVISING THAT I DO NOT KNOW IF THEY ARE AUTHENTIC. THE DUST BAG WILL BE INCLUDED**
