The Birkenstock Women's Arizona Big Buckle Shearling Oiled Leather Sandals - Narrow is a soft and comfy version of a classic style. Wear these fuzzy sandals when the temperature drops and you're not quite ready for closed-toes. The anatomically shaped cork-latex footbed is covered with high-quality shearling (sheep or lamb) to regulate temperature and enhance comfort. This warm and breathable material is also present on the underside of the adjustable straps, creating a luxurious experience on the top and bottom of the foot. The exterior is built with premium oiled leather, and the EVA outsole supplies cushioned steps in a lightweight fashion.
