Are plimsoll shoes related to the Plimsoll line on a commercial ship?
A plimsoll shoe or simply plimsoll is a type of athletic shoe with a canvas upper and rubber sole, developed as beachwear in the 1830s by the Liverpool Rubber Company (later to become Dunlop). The shoe was originally, and often still is in parts of the UK, called a 'sand shoe' and acquired the nickname 'plimsoll' in the 1870s. This name derived, according to Nicholette Jones' book "The Plimsoll Sensation" because the colored horizontal band joining the upper to the sole resembled the Plimsoll line on a ship's hull, or because, just like the Plimsoll line on a ship, if water got above the line of the rubber sole, the wearer would get wet.
We'd been looking at an incoming container ship and I was wondering if the plimsoll shoe got its name because of the resemblance of the demarcation between the shoe's rubber sole and canvas upper and the Plimsoll line on the ship.
The Web is a wonder.
