Birkenstock Arizona 2-Strap Sandal in 'Smooth Black Natural Leather', Unisex Smooth Natural Leather Upper; the original Arizona Sandal from Birkenstock made in Germany. With smooth leather uppers, these Birkenstock Arizona black sandals are incredibly smart. Plus, they are comfortable as they feature cork/latex footbed, double adjustable straps and matching black shock absorbing EVA soles. The anatomical shape of the footbed ideally supports the natural walking action of your foot. Construction of the sandal is designed to offer the ultimate in comfort and support beginning with the footbed edge that has been deliberately elevated to protect the toes. The toe grip is there to guide the toes to sit in their natural position and to promote their natural rolling movement. Birkenstock makes the Arizona Sandals intentionally roomy (both in length and in width) for added comfort so they tend to run long and wide: our customer say they are about 0.5 (half-a-size) larger than your average sandal . Most people prefer it this way since the buckles can be adjusted for a tight fit. In fact, this is part of their appeal. Birkenstock footwear is designed and sized to provide a roomy fit allowing your toes and feet to wiggle and be free.
