According to DJ, producer and cultural historian Al Fingers in his book, "Clarks in Jamaica", this trend started in the late 1960s when the emerging youth culture of the recently independent Jamaica adopted the Clarks shoes as part of their "uniform." "The original gangster rude boy dem, a Clarks dem wear," producer Jah Thomas tells Fingers in the book. "And in Jamaica a rude boy him nah wear cheap ting." Writes Fingers, "In the early 70s, the rude boy/desert boot association became so strong that young males risked a beating by police simply for wearing a pair. 'You must be a thief,' the police would say. 'How else would you afford such expensive Clarks?'" He tells the story of an infamous Kingston police officer called Joe Williams, who carried out a raid on a dance being run by producer and label boss "Sir Coxsone" Dodd. The DJ Dennis Alcapone recalls the arrival of Superintendent Williams: "He tell the DJ to turn the sound down, and he say: 'All who's wearing Clarks booty, stand on that side of the dance. And who's not wearing Clarks booty stand on this side.' Because he knows that rude boys wear them, so that is a way of identifying them."
