Plimsoll (n.)youdaoicibaDictYouDict
"mark on the hull of a British ship showing how deeply she may be loaded," 1881, from Samuel Plimsoll (1824-1898), M.P. for Derby and advocate of shipping reforms (which were embodied in the Merchant Shipping Act of 1876). Sense extended 1907 to "rubber-soled canvas shoe" (equivalent of American English sneakers) because the band around the shoes that holds the two parts together reminded people of a ship's Plimsoll line; sense perhaps reinforced by sound association with sole (which sometimes influenced the spelling to plimsole). The name is of Huguenot origin.

1590s, "one who sneaks," agent noun from sneak (v.). Meaning "rubber-soled shoe" is attested from 1895, American English; earlier sneak (1862), so called because the shoe was noiseless. See also plimsoll; another early name for them was tackies (1902), from tacky (adj.1).
The night-officer is generally accustomed to wear a species of India-rubber shoes or goloshes on her feet. These are termed 'sneaks' by the women [of Brixton Prison]. ["Female Life in Prison," 1862]
