The BIRKENSTOCK Atacama is a variation on the classic Arizona and is the perfect sandal for anyone who is on their feet all day. The pin buckles have been replaced by hook-and-loop fasteners and the heel of the sole has been reinforced. Perfect for all active and adventurous BIRKENSTOCK fans. The polyurethane sole is affixed to the footbed in two layers and therefore offers maximum flexibility, grip and durability. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor which was reinterpreted with a futuristic look. Anatomically shaped cork-latex footbed Upper: Birko-Flor Futura Footbed lining: polyurethane (PU) Sole: light polyurethane sole (PU) Details: two straps, each with an individually adjustable hook-and-loop fastener
