We're a shoe-free household and since COVID the shoes we are wearing outside are banned to the outdoor hallways of our condo building. Trying to limit the number of shoes that collect there, as we're not even supposed to leave shoes or anything in our hallways usually according to HOA rules. So it's just a pair of sneakers for him and for me (Allbirds for me). They have relaxed the HOA rules but we still don't want to get ridiculous with a pile of shoes out there, since we have cleaners coming in more frequently to disinfect the common areas.
At home we are wearing socks, as we normally do. DH wears thick colorful knee high LL Bean fleece socks as he's always freezing. I wear New Balance running socks in various weights depending on the weather. Right now it's snowing so they are thicker socks, but still only ankle height.
Occasionally in the past I've borrowed DH's fleece knee highs, but only if I'm sick and have fever and chills! I run much hotter than that. He sleeps in his socks regularly. I normally kick mine off early on before falling asleep, even in winter!
