The phrase “cold feet,” meaning a sudden loss of nerve or courage, has been in use since at least the early 1600s, but its exact origin is genuinely uncertain. Linguists and literary scholars have traced it through Italian proverbs, German novels, English plays, and American gambling halls, each offering a slightly different story about how chilly extremities became shorthand for backing out.
The Oldest Known Use: A 1605 Play
The earliest recorded appearance of something close to “cold feet” comes from Ben Jonson’s 1605 play Volpone. In the play, a character disguised as a street vendor references a Lombard proverb, saying he is not “cold on my feet” and won’t be selling his goods at bargain prices out of desperation. The Lombard proverb he’s quoting, “avegh minga frecc i pee,” didn’t mean fear or hesitation at all. It meant being so broke that you’d sell things cheaply just to survive. Kenneth McKenzie, a former professor of Italian at Princeton University, credited this as the phrase’s first appearance in English.
This is a crucial detail because it shows the phrase originally had nothing to do with courage. In northern Italy, having “cold feet” meant having no money. The connection to nervousness or backing out came later, and exactly how that shift happened is the part nobody can pin down with certainty.
From Poverty to Fear: The Meaning Shifts
The next significant sighting comes from German author Fritz Reuter’s 1862 novel Seed Time and Harvest (originally Ut mine Stromtid), where a character’s “cold feet” are mentioned in a context closer to the modern sense of doubt or hesitation. By the time the phrase surfaces in American English in the 1890s, the transformation is nearly complete.
The Online Etymology Dictionary dates the figurative English meaning, “fear or doubt that reverses an intention to do something,” to 1893 and notes it as American English. Some of the earliest American usages appear in the context of gambling, describing a player who lost the nerve (or possibly the funds) to stay in the game. That gambling connection may actually be the bridge between the old Italian meaning about money and the modern meaning about fear. A card player who runs out of cash and a card player who loses his nerve both end up doing the same thing: walking away from the table.
American author Stephen Crane then helped cement the phrase in popular usage. In 1896, he added the line “I knew this was the way it would be. They got cold feet” to the second edition of his short novel Maggie: A Girl of the Streets. For a long time, Crane was credited as the phrase’s originator, though the earlier examples clearly show he was building on something already in circulation.
Why Cold Feet Actually Make Biological Sense
One reason the idiom stuck so well is that anxiety genuinely does make your feet cold. When you’re stressed or frightened, your nervous system triggers a rapid response that redirects blood flow away from your hands and feet toward your core and major organs. This is part of the fight-or-flight response: your body prioritizes survival over keeping your toes warm. Research published through the National Library of Medicine confirms that blood flow to the extremities drops quickly through nerve-driven constriction of blood vessels, pooling blood in the torso and deep body core instead.
So while the idiom’s literary origins trace back to money and gambling, the physical experience is real. Someone standing at the altar or about to make a life-changing decision might literally feel their feet go cold as adrenaline kicks in. Whether the phrase was coined with this physiology in mind is unknowable, but the body’s response gave the metaphor staying power.
The Military Theory
You’ll occasionally see claims that “cold feet” originated with soldiers retreating from battle due to frostbite or trench foot. While prolonged exposure to cold, wet conditions did cause serious foot injuries in combat, particularly during World War I, this theory doesn’t hold up chronologically. The phrase was already well established in English by the 1890s, more than two decades before trench warfare made “trench foot” a recognized medical condition. The military connection appears to be folk etymology: a plausible-sounding story that doesn’t match the historical record.
How Other Languages Handle the Same Idea
Interestingly, not every language links fear to cold feet. French speakers are more likely to say “les sueurs froides” (cold sweats) or “il a eu peur de s’y brûler les doigts” (he was afraid of burning his fingers). The cold is still there, but it moves to a different part of the body, or heat replaces cold entirely. The original Lombard proverb that started it all connected cold feet to empty pockets, not fear. English is somewhat unusual in how thoroughly it remapped the phrase from financial desperation to emotional hesitation.
The trajectory of “cold feet” is a case study in how idioms evolve. A regional Italian proverb about poverty traveled through a London stage play, surfaced in a German novel, landed in American gambling halls, got picked up by a famous novelist, and eventually became the go-to phrase for anyone backing out of a wedding, a business deal, or a skydiving appointment. Each step nudged the meaning a little further from its origin until the connection to money disappeared entirely, replaced by something the body actually does when fear takes over.
