The design of the Birkenstock Catalina was inspired by the classic Madrid with a strap and metal buckle. The slightly wider strap lends this sandal a modern and elegant appearance. Here, we see the sandal with a silky sheen finish. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor®.Brand: BirkenstockFlat heelUpper: Birko-Flor®Lining: LeatherSock & Sole: Cork Available in: Pearl White 0.00 1 True Footwear 4.99 4.99 Birkenstock Women’s Graceful Pearl Catalina Birko-Flor Sandals | Grattan
