That's been the ethos driving the Nike Dunk since it launched in 1985. Back then, seven college basketball teams broke an unwritten rule and matched their Dunks to their uniforms. A riot of color ensued, and the Nike Dunk has been a symbol of individual expression ever since. Players, skaters and collectors picked up on the shoe and continue to influence it today.
