The Birkenstock Mens Tatacoa CE BF Futura Black is a variation of the classic Milano 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 The pin buckles have been replaced by hook-and-loop fasteners and the heel of the sole has been reinforced.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.
