Classic two-strap style in a variety of materials with fully adjustable straps and shock-absorbing EVA sole. Suede upper: thick yet supple leathers without additional dyes to keep the leather breathable, durable and comfortable. Soft footbed: A foam layer is inserted between the cork layer and the suede liner of the original Birkenstock footbed. Millions of microscopic air bubbles cushion your feet while providing moderate arch support. EVA sole flexible, lightweight, durable and shock absorbing.
