Birkenstock Women’s Arizona EVA Narrow-Fit Sandals are a true classic. The high-quality, odour-neutral EVA Narrow-Fit is designed to combine numerous positive attributes. Anatomically shaped BIRKENSTOCK footbed in EVA Narrow-Fit One-piece EVA Narrow-Fit upper, lining and sole Ultra lightweight and highly flexible Waterproof design Modelled on the cork sandal, Birkenstock Women’s Arizona EVA Narrow-Fit Sandals are made from ultra light and highly flexible EVA Narrow-Fit. These sandals are waterproof, ultra lightweight and therefore extremely easy to care for. 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.
