These are brand new. I did try them on in my home a few times trying to convince myself to keep them, however they are just too tall for my comfort. I have tile floors so there are some scratches on the soles. Size 37. I typically wear a size 8 and these fit me well. 100mm heel. 100% authentic, purchased in Paris. I no longer have the original receipt. Comes in original box, with dust bags and replacement tips for heels. No trades. These shoes currently retail for $795 plus tax. Poshmark will authentic all purchases over $500.
