It, uh, depends on the shoes. If you're wearing, uh, tennis shoes, then athletic socks (pushed down) can work. Sandals can work. Thin dress socks pulled up do not work. They look too much like dress socks pulled up.

Bite the bullet and get a pair or two of good hose. They'll last longer and be more comfortable than cheap socks, and look better, to boot. If you know a knitter, trade somethng for a pair of handmade hose. Mow their yard or rake their leaves or take thei children to the playground or something. Money and the lack thereof need not hold a person from having good stuff.
