Many are double sided for safety

Right foot: sock says L.

Back to the psych ward.

(Real for a second: the way we neglect the mentally ill in the USA is atrocious)

And I think they are labeled L and R, because I see an L on the right foot.

You could probably walk into the ER and just ask the triage nurse if you could have some socks lol. Most medical staff love just giving shit away, at least in my area. Also, if you're not bothered by the questionable nature of second hand underwear, I've seen tons of grippy socks in thrift stores so that may be worth a look

for real though, i like walking around barefoot but the climate here's such that i only get to do that 3 months out of the year.

the other nine months i walk around indoors and the little bumpy bits help me feel like i'm walking on actual dirt/rock instead of boring floorboards.

There are a lot of options if you Google psych ward socks

Those trampoline park businesses!
