Steeped in history, Birkenstock, the German family-owned company’s roots can be traced back to 1774. The brand has stood the test of time due to holding excellent comfort, high functionality, and extraordinary quality at their core of their company ethos. The high level quality of Birkenstock footwear is the result of carefully selected, premium materials from sustainable sources, which has been integral since the beginning. With well-being at the forefront of their designs, Birkenstock supplies three sustainable footbed designs. The classic models with the original footbed have a structure composed of sustainable jute, cork, and suede. This combination is shock-absorbing, flexible, and allows the Birkenstock sandals to mold perfectly to your feet. Adding an extra foam insert to the original footbed, the integrated soft-footbed option contains small air bubbles that provide even more comfort. Birkenstock also supplies the EVA, which is fully constructed with an ultra-lightweight flexible EVA material, that is great for all weather, the beach, or the pool. The classic Birkenstock Arizona with two straps can be found in all three footbed designs and the Boston clog in the original footbed.
