Birkenstock Men’s Arizona CT Artic Old Sandals are a genuine classic that has won the hearts of men and women for decades with its timeless design. Oiled nubuck leather upper Anatomically shaped cork-latex footbed Suede footbed lining Polyurethane sole 2-component sole 2 straps each with an adjustable metal pin buckle Birkenstock Men’s Arizona CT Artic Old Sandals are designed with all adventurous and active Birkenstock fans in mind. The polyurethane sole is foamed onto the footbed in 2 layers, which results in excellent non-slip properties, great flexibility and a long life. The upper is made of especially thick, oiled nubuck leather with unfinished edges. Deep heel cup The very deep moulding in the heel area supports the foot tissue and holds the heel bone firmly in its natural position. This provides the foot with nearly as much support when it is in a sandal as when it is in a closed shoe. Heel mould Activates the calf muscles, stabilises the back of the foot and improves gait and coordination. Interior and exterior longitudinal arch supports The arch supports that run alongside the sides of the footbed surround the tarsal bones inside and out. This gives the foot the stability it needs when it takes a step. Transverse arch support The support that runs through the middle of the footbed stabilises the metatarsal bone. In this way, the transverse arch support helps ensure that the foot has a naturally straight and solid stance. Toe grip There are raised indentations at the front of the footbed near the toes. Thanks to the toe grip the toes remain loose and spread out in their natural position. The indentations also support the natural rolling motion of the toes. Footbed edge The footbed is drawn up especially high at the front. As a result, the high footbed edge protects the toes during the rolling motion of the foot.
