This is a well-known phenomenon in Nordic countries I believe. There is a verb "narskua" in Finnish which is only used to describe the sound of walking on snow in below freezing temperatures. Google AI tells me: "The Finnish word narskua translates to "crunch" or "scrunch" in English. It's an onomatopoetic verb that describes the sound snow makes when you step on it in very cold temperatures"
