BIRKENSTOCK is a German footwear brand founded in 1774 by shoemaker Johann Adam Birkenstock, with 95% of its product range remaining manufactured in Germany. The brand constructs its footbeds using a layered structure of natural cork, latex, and jute, delivering both supportive cushioning and breathability. It pioneered the "Footbed" concept—an anatomically shaped insole that has become the cornerstone of its design philosophy.
