I don't particularly care to wear socks if I don't have to; I own many pairs of sandals as a result.
These are my favorite socks:
They make my North Face Hedgehog XCRs super-comfy and they don't look weird when I wear my Doc Marten T-strap Mary Janes. They also keep my toes cushioned nicely in the Docs so they're not sliding around in the huge steel toe box. I wish I had more pairs.
I also really like Nike's crew socks. I have about 20 pairs of those, mostly because I can't stand to deal with a bunch of socks of different colors.
