The Birkenstock Arizona Birko-Flor Narrow Fit Sandals are a classic design that provide ultimate comfort. The shoes are made from Birko-Flor synthetic leather and have a contoured cork-latex footbed for support. The footbed is lined with suede for extra comfort and the sole is made from EVA for a lightweight feel. There are two adjustable straps with metal pin buckles and a deep heel cup that cradles the heel. Arch supports are included for stability, a raised toe bar to encourage natural gripping motions, and more toe room for better balance and proper alignment.
