THE CRANE in Port Leather Our luxe square-toe ballet flat is crafted of premium tumbled Nappa leather. The soft-bounce quilted insole, covered in soft and durable leather, is complete with arch support and a heel cookie. We designed a more polished heel, which dresses up our chic Crane while still remaining light and flexible. The flat is complete with our signature grosgrain backtab. Worn twice. Signs of wear on the bottom. Folded a bit as pictured from storage.
