Registered with the church in 1774, Birkenstock is known for its ergonomic shoes, the world's first pair of elastic insoles with arched arches, which earned Birkenstock the reputation of "King of Healthy Shoes" and designed healthy shoes for wounded soldiers during World War I. Birkenstock's most iconic slippers are the Arizona and Boston, which use the "thoughtful arch soles" developed by Birkenstock in the early 20th century, with the sole of the shoe close to the arch of the foot and the surrounding area is cocked to protect the sole of the foot. The combination of cork and rubber, comfortable and not deformed, is not only a healthy choice, but also a fashion icon, active in the global market, capturing the favor of all kinds of hipsters and celebrities. With an average price of several tens of euros a pair, Birkenstock is now a must-have shoe for those who pursue fashion and health.
