Grippy socks are standard issue for all in-patients in most US hospitals because they prevent falls and the floor is nasty. Seriously please wear them during your stay.
American here. I try to remember that other folks outside the US don’t have the same negative association we do with that word. It certainly helps ease the stigma I have for it when it’s said in good fun in a conversation. I still can’t bring myself to say it or write it often though.
