A type of footwear that is worn over regular shoes to protect them from water, snow, or cold weather.

Overshoe → It is formed from "over-" (meaning above or on top of) and "shoe" (from Old English "sceo", meaning foot covering). The word "overshoe" refers to a shoe that is worn over another shoe, typically for protection or to keep the inner shoe clean.
Think of wearing a shoe 'on top of' ('over-') another shoe — that's why an overshoe is a protective covering for your regular shoes.
