A gumshoe is a slang term for a detective, often used in the context of private investigators or police detectives. The term originated in the early 20th century, referring to the soft-soled shoes worn by detectives to move quietly while investigating. Gumshoes are typically portrayed as resourceful and observant, using their skills to solve crimes and uncover secrets. In popular culture, gumshoes are often featured in film noir and detective fiction, embodying the archetype of the hard-boiled detective. They are known for their gritty determination and ability to navigate the underbelly of society, often working alone or with a small team to crack cases and bring criminals to justice.
