Socks for ultra-casual

[TheGratefulNed]

Of the options given, I'd say either kilt hose worn up or the calf-length athletic socks. I agree with Wareyin that scrunched hose really only look good with boots.

If you don't mind spending a little bit of money, you can probably find an inexpensive pair of rugby/soccer socks for less than you'd spend on most kilt hose (even cheap ones). They will breathe better than kilt hose (especially if they're wool), are designed to come up to your knee like hose do, and are generally good about staying up even through strenuous activity (at least until the elastic starts to wear out, then you just wear a pair of flashes with them or at least the elastic garter off some flashes).
