Converse's "shoes are boring" slogan stems from an effort by the company to differentiate itself from other shoe brands. The company also wants to claim the word "sneakers" as its own, making Converse the quintessential sneaker company. The "shoes keep it clean" slogan was created in the same spirit. In the 1950s, when the company first started making shoes, the "Converse for comfort slogan" was used to emphasize that the stylish shoe also felt great on the feet.
