. The 'Arizona' sandal is one of Birkenstock 's most recognisable styles, and there's no question as to why they're so popular. Made from soft and flexible suede, they're set on a contoured cork footbed that conforms to the shape of your foot to provide arch support and have exceptionally comfortable foam cushioning.
