I took my sims for a day of winter sports in Mt Komorebi. I travelled to the Onsen bathhouse lot, then had both sims go skiing from there. When sims ski, the game automatically puts them in skiing boots, overriding whatever shoes they were wearing before. That is fine for skiing. Then my sims also went sledding and hiking. They kept the game assigned skiing boots on. That was also okay. You can hike in skiing boots.
Then they returned to the onsen, to end their snow day with a relaxing soak. They changed into swim wear to shower. The skiing boots stayed on. That was not fine. Then they went into the hot springs. In swim trunks and skiing boots. Definitely hilarious but not acceptable hot spring behaviour.
I cannot take the boots off them, because I also didn't put them on and they are not part of any outfit.
Boots get removed from the sims on travel, so they aren't stuck like that forever, just while they are on the onsen lot, but it's still weird and immersion breaking. It's alright that the game gives them skiing boots, but maybe they could be tied to cold weather and/or athletic outfits, and disbled for swimwear. It just looks very strange if sims relax in the hot springs with big stompy snow boots on.
Bug is reproducible for me, the first skiing interaction triggers the boots, and then the boots are applied to all outfits the sims have, including swim wear. Which might have always been like this but you only notice it when you have sims change into swimwear shortly after they went skiing. Maybe the boots should just be taken off when sims change outfits or finish skiing? The bowling shoes get taken off when sims finish bowling after all.
