What is the relationship between devo and Birkenstock Davos slippers?

BirkenstockDavos is a sandal brand, originally designed mainly for monarchs and nobles. Birkenstock is the main brand, and Davos is the series. The launch of BirkenstockDavos shoes has played a very high role in the creation and improvement of human shoes, no less than Nike's creation of AF shoes. Although Birken shoes are very comfortable/beautiful, they have patent rights, so there is no large-scale similar product on the market in the past few years. However, due to the timeliness and regionality of the patent right (if the German patent is not applied in China, China District will not be protected), there are many Birken shoes on the market now, just for these two reasons. There are also many brands. At present, there are many brands producing Birken shoes in Germany: SoftmocNAOTMephisto (although most of them are produced in Germany, they are actually produced in China, Thailand, Malaysia and other Asian countries). German Birken shoes brand is more mature than domestic brands. Strict workmanship and materials. Nowadays, Birken shoes have become synonymous with this kind of sandals, just as Simmons brand has become the name of a certain bed. DEVO may be a product of China, just like famous brand Sassoon, you may buy Sha Yi carelessly. I bought a bottle of Wahaha mineral water before.
