Plimsolls (British English) are "low-tech" athletic shoes and are also called "sneakers" in American English. The word "sneaker" is often attributed to American Henry Nelson McKinney, who was an advertising agent for N. W. Ayer & Son. In 1917, he used the term because the rubber sole made the shoe's wearer stealthy. The word was already in use at least as early as 1887, when the "Boston Journal" made reference to "sneakers" as "the name boys give to tennis shoes." The name "sneakers" originally referred to how quiet the rubber soles were on the ground, in contrast to noisy standard hard leather sole dress shoes. Someone wearing sneakers could "sneak up", while someone wearing standards could not.
