Sounds like this come from everyday foley recordings of winter walking, shared as short reusable effects rather than from a film or game. The Spanish title botas en la nieve reflects how creators label and search for it in Spanish, while English speakers look for snow crunch or boots in snow. Because it lasts less than a second, editors loop or repeat it to build longer walks. It stays popular for seasonal videos, games and animations that need a believable snow step without recording their own.
