The Birkenstock Women’s Arizona Suede Leather Soft Footbed Regular Fit Sandals have adjustable straps and a cork footbed that conforms to the shape of your foot for a custom fit. The sandals are made of soft and flexible leather with a light surface nap and have a contoured cork footbed that conforms to the shape of your foot. They also feature pronounced arch support with an extra layer of super soft foam cushioning, a lightweight EVA sole for cushioning and shock absorption, and are lined with suede. The sandals have a flat heel shape and a deep heel cup that supports the foot tissue and holds the heel bone firmly in its natural position. They also have a heel mould that activates the calf muscles, stabilises the back of the foot, and improves gait and coordination. The sandals have interior and exterior longitudinal arch supports that surround the tarsal bones inside and out, and a transverse arch support that stabilises the metatarsal bone. They also have raised indentations at the front of the footbed near the toes that support the natural rolling motion of the toes. The footbed is drawn up especially high at the front to protect the toes during the rolling motion of the foot.
