Birkenstock Arizona sandals in brown oiled leather. This iconic style is known for its legendary comfort, anatomical cork-latex footbed that molds to the foot with wear, and flexible, lightweight EVA sole. They feature two adjustable straps with metal pin buckles and are designed for casual, everyday wear.  Care and Maintenance Given the worn condition of your pair, here are some care tips: Cleaning the footbed: Remove surface dirt and oils using sandpaper (around 150 grit) in circular motions or a specialized nubuck block. A suede brush can then lift the nap and remove dust. Cleaning the straps: Wipe the straps with a damp cloth to remove light soiling. For heavier soiling, a mixture of mild soap and water can be used sparingly, followed by wiping with a clean, damp cloth. Conditioning the leather: Since leather is a natural material that can dry out over time, apply a leather conditioner or lotion with a soft cloth after cleaning to keep the material supple and prevent cracking. Drying: Always allow the sandals to air dry completely at room temperature, away from direct sunlight or heat sources, to prevent material damage or mold growth. Protection: Regularly apply a water and stain repellent spray to protect the leather from the elements.
