The BIRKENSTOCK Sydney proves that form and function are anything but mutually exclusive. With its two simple straps, it's a real hit with women who want both high fashion and comfort. This version features a handpainted, floral pattern in a watercolor look. The creative production process means no two pairs are the same just like flowers. This popular sandal has been given an update in a new material, with a vegan version now available. It is entirely free of animal products, as verified by independent testing laboratories. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor®. These are in great used condition.
