I've had socks from Thorlo, Wigwam, Helly Hansen, Burton, and on and on. Got turned onto Smartwool a couple yrs ago and they're by far the best. They don't fall down or bunch up, super warm and comfortable, do a good job of wicking, and come in various thicknesses. I have a few pairs of light and medium.
