These sandals are a collaboration between cafooca, an Okinawa-based shark leather brand, and Ota Shoe Store, using shark leather. The sole is Vibram's shark sole, making these a truly special item with a focus on sharks. I've only worn them once or twice, so I think they're in beautiful condition. I'm selling them because the size didn't fit me. Size L: Best for those who usually wear 27cm shoes Thank you for looking.
