Johann Adam Birkenstock established his namesake brand in Langen-Bergheim, Germany, in 1774. Johann was a cobbler by trade, but the Birkenstock sandal line was not an instant hit. Birkenstock only gained popularity and notoriety after more than a century and multiple generations at the helm. The popularity of men's Birkenstock sandals began to grow in the 1890s when Konrad Birkenstock invented the first flexible insoles. Konrad evolved his contoured arch support by integrating them into the sandals at the beginning of the twentieth century, and this iteration became the forerunner to the Birkenstock sandals that we recognize today. With their revolutionary footbeds, this wonderful company dominates the men's sandals and mules market, and here at Brother2Brother, we are delighted to offer a broad choice from the latest collection. Enhance your Summer look with a pair of men's Birkenstock sandals from Brother2Brother online.
