Established in the late 18th century, and still headquartered in the Neustadt region of Germany, Birkenstock is the original sandal brand. This footwear company rose to prominence thanks to an American entrepreneur who introduced their styles to San Francisco in the 1960s. The sandals contoured leather straps, rubber soles, and durable cork footbeds that contoured to their wearers' feet became fixtures on Flower Children around the Bay Area. As the second decade of the 21st century comes to an end, Birkenstocks remain popular around California and are now a worldwide phenomenon. Their sandals are ideal for warm and dry weather, with timeless models like the Arizona and Gizeh being staples on sidewalks and beaches throughout Canada, Asia, and Europe.
