5.5 / US 8 HONESTLY THE BEST PRICE YOU ARE GOING TO FIND. I confused the sizing & bought from someone & can't return. I'm a 4.5. Even these in fair condition go for $55 and up. Feel free to look them up! Step out in style with these sleek black perforated leather slip-on shoes. Perfect for any occasion, they offer comfort and elegance. A must-have for your wardrobe.
