query: When were athletic sneakers first used?
passage: Sneakers
These shoes acquired the nickname 'plimsoll' in the 1870s, derived according to Nicholette Jones' book The Plimsoll Sensation, from the coloured horizontal band joining the upper to the sole, which resembled the Plimsoll line on a ship's hull. Alternatively, just like the Plimsoll line on a ship, if water got above the line of the rubber sole, the wearer would get wet.[7]
passage: Sneakers
Sneakers (also known as athletic shoes, tennis shoes, gym shoes, sport shoes, runners, or trainers) are shoes primarily designed for sports or other forms of physical exercise, but which are now also widely used for everyday wear. The term generally describes a type of footwear with a flexible sole made of rubber or synthetic material and an upper part made of leather, synthetic substitutes or cloth.
