A plimsoll is a type of athletic footwear constructed from a canvas upper and rubber sole. Its development is seen as the origins of sports footwear, and it was originally development as beachwear by the Liverpool Rubber Company (UK). Originally known as sandshoes, they only became known as plimsolls in the 1870s. This name probably originated from the colored horizontal band that joins the upper to the sole that resembles the Plimsoll line on a ship’s hull.
In many parts of North America, plimsolls are referred to as “Cons”. This refers to a popular brand of Plimsolls – Converse’s Chuck Taylor All Star shoe.
