Sneakers are shoes primarily designed for sports or other forms of physical exercise. Sneakers have evolved to be used for casual everyday activities. 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 or synthetic materials.
Examples of such shoes include athletic footwear such as: basketball shoes, tennis shoes, cross trainers and other shoes worn for specific sports.
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.
Sport is generally recognised as system of activities which are based in physical athleticism or physical dexterity.
Some sports allow a tie game; others provide tie-breaking methods, to ensure one winner and one loser.
A number of such two-sided contests may be arranged in a tournament producing a champion.
Many sports leagues make an annual champion by arranging games in a regular sports season.
