Authentic. I love these shoes. I still have the box from Saks, extra heel tips and dust bag. Very gently loved. Stunning. These are actually navy blue, but they are super dark and I’ve actually worn them with solid black so you can do both. No creepy toe marks, these are like a work of art and make your legs look stunning. I’m moving and trying to sell before I have to pack up. Pet free, smoke free shoe lover. 5 inch heel, 1 inch platform.
