“shoe” vs. “shoo”
Use "shoe" for the item of footwear (noun or verb meaning to fit with shoes); use "shoo" for the interjection/verb meaning to drive something away — and remember it's "shoo-in," not "shoe-in."
shoe
"Shoe" is a noun naming an item of footwear, or a verb meaning to fit someone or something (typically a horse) with shoes ("shoe a horse"). It comes from Old English "scoh," part of the core Germanic vocabulary for basic clothing and equipment, essentially unchanged in meaning across the entire recorded history of English.
shoo
"Shoo" is an interjection and verb used to drive away an animal or person, typically by waving one's hands and making the sound "shoo!" ("shoo the cat off the counter"). It's an example of onomatopoeia — a word that imitates the sound or gesture associated with its meaning, in this case the sharp, dismissive sound people make to scare off pests or unwanted animals, and it has no connection at all to footwear.
The real distinction
"Shoe" names footwear (or, as a verb, means to fit with shoes), while "shoo" is an exclamation and verb meaning to drive something away, and the two are unrelated in meaning despite near-identical pronunciation in most dialects. The words rarely cause real confusion since context is almost always unambiguous — a sentence about footwear will never plausibly also be about shooing away a pest — but the spelling mix-up does occur in casual writing, particularly among younger writers or in fast texting, where the double "o" of "shoo" might be dropped in favor of the more familiar "shoe." A simple check: if the sentence involves footwear, cobblers, or fitting a horse, it's "shoe"; if it involves chasing away an animal, pest, or unwanted visitor, it's "shoo," often appearing as a standalone exclamation ("shoo!") rather than as part of a longer sentence. The word "shoo-in," meaning a candidate who is certain to win, derives from this same sense of driving something along easily, not from footwear — a common source of confusion worth flagging, since some writers mistakenly write "shoe-in" instead of the correct "shoo-in." It's also worth noting that "shoe" appears in a wide range of idioms unrelated to footwear directly, such as "if the shoe fits" (accepting a criticism that applies to you) and "the other shoe drops" (an anticipated bad outcome finally occurs), both drawing on the everyday, universal nature of footwear as a metaphor. "Shoo," by contrast, remains almost entirely limited to its literal sense of driving something away, with the notable exception of "shoo-in," a term borrowed from horse racing that described a horse allowed to win easily, or "shooed in" without real competition.

Memory trick
Picture a single shoe (one "o") on a foot, versus shooing something away with two hands waving, matching the double "o" in "shoo." And remember: it's a "shoo-in," from shooing someone easily along, never a "shoe-in," even though the spelling error is extremely common.
