For over 230 years, Birkenstock has emphasized the simple principles of health and wellness, quality workmanship and materials as well as a respect for the environment. Birkenstock created the original contoured footbed that supports and shapes to your foot when walking! And it's made of 100% natural and renewable cork. You can feel good that you are supporting your feet and the environment at the same time. Call it sustainable comfort. Birkenstock sandals are designed and sized to provide a roomy fit allowing your toes and feet to wiggle and be free. Featuring a contoured cork footbed, a deep heel cup, and a roomy toe box, Birkenstock clogs and sandals provide more than simply cushioning. Birkenstock footwear provides the perfect balance of firm support and shock resistance allowing your feet and body to be naturally supported.
