To anyone looking for a pragmatic solution to a sock shortage, I can't recommend this1 24-pack enough. Unlike most socks that pretend to be 100% cotton, these actually are, which means they aren't as durable as plastic alternatives, and feature a seam that can get in the way, but they provide unparalleled comfort. Especially if you don't mind going through multiple pairs on busy days.
