The first Doc Martens was designed and made by Dr. Klaus Martens during World War II. The first pair of boots was sold in Munich in 1947. Before the first pair went to sell, the heel was redesigned, a logo was added - a yellow laces and these are the Doc Martens we all know today. Boots can have between three and eight holes. More than 3.2 million "Martens" are produced annually. Unlike most shoes, the leather is sewn for the sole, and does not stick or put the glue on. The company spends 42,000 kilometers of yellow thread and 10 million pairs of ties per year.
