It is said that Henry VI. wore half-boots laced at the side, and about the same time was introduced the shoe or clog called the galage or gologe, meaning simply a covering; to which is attributed the origin of our word golosh. This cannot be correct, as Chaucer, who died twenty years before Henry VI. was born, uses the word. The word comes to us from the Spanish galocha (wooden shoes); German, galosche.
