I bought these from another resale site, where the seller didn’t inform me that one shoe is slightly defective. Please exam the photos. They are still wearable, you may be able to take them to a shoe repair, I haven’t tried. One shoe tilts outward a bit, making a little funky walking BUT you can still walk fine and use the shoes, in my opinion. See video. Size 36- I would say it fits a 5.5/6 narrow. Authentic!
