In the 1960s, Dr. Klaus created the infamous 1460 Doc Martens with air-cushioned soles. He showcased the prototype to a friend from university, and production began shortly after using surplus military supplies. Once released to the public, the clunky boot was adopted by older women who had a knack for sensible footwear. Doc Martens gained popularity in the 70s among members of counterculture circles, activists, punks and the queer community. A big factor in their adoption by those on the margins of society was their price tag, accessibility and availability in secondhand shops.
