Authentic, New slides size 41 but run small, I would say equivalent to a women’s 8.5-9. They run narrow, calf skin leather upper. Beautiful and classy but just a bit too big for me. Comes with dust-bag and box. I’m normally a size 7.5-8 and I have another pair in a different color, size 40 which fits. Serious inquiries only. No low ball offers. Will Only sell on Poshmark and will not contact potential buyers via any other alternate methods so don’t wast your time. Thank you!
