Dr. Martens is an English footwear and clothing brand, headquartered in Wollaston in Wellingborough, Northamptonshire. They also make a range of accessories – shoe care products, clothing, bags, etc. In addition to Dr. Martens, they are also commonly known as Doc Martens or Docs. The footwear is distinguished by its air-cushioned sole (dubbed Bouncing Soles), upper shape, welted construction and yellow stitching. The boots have been the choice of footwear among various groups in British culture: in the 1960s skinheads started to wear them, "Docs" being the usual naming, and by the late 1980s, they were popular among scooter riders, punks, goths, some new wave musicians, and members of other youth subcultures, most notably the grunge fashion scene in the early nineties. In 2006, Griggs' 1460 Dr. Martens AirWair boot was named in the list of British design icons which included Concorde, Mini, Jaguar E-Type, Aston Martin DB5, Supermarine Spitfire, Tube map, World Wide Web and the AEC Routemaster bus.
