You can actually get away with the same exact pair of socks a few times if you get good merino wool. My cotton sucks smell the moment I put them on, but my wool socks don’t start smelling until day three or four.

So that’s what I do, I rotate through a few pair of wool socks so I don’t have to fold them as often. Works pretty well, and it makes for light packing if I go hiking or something.
