These Birkenstock Arizona Vegan Leather Sandals combine the classic style you know with added comfort. The contoured cork-latex footbed is designed to mold to your feet and provide custom support. Inside, it is lined with soft genuine shearling, and the flexible EVA sole is lightweight. There are two adjustable straps with metal pin buckles and a deep heel cup for extra support. The heel mould activates the calf muscles, stabilizes the back of the foot, and helps with coordination. Longitudinal and transverse arch supports stabilize the tarsal and metatarsal bones. There is also a toe grip that keeps the toes spread out in their natural position. The footbed edge is especially high to protect the toes during the rolling motion of the foot.
