I have several pairs of Smartwool socks in varying degrees of wore-out-ness. I've got other brands of merino wool, poly, blend, etc, socks that just aren't as good. Most, not even close. But, I can't believe a person needs to spend $17 to get a decent pair of socks.
My deal is that my feet sweat a lot, then feel clammy in the summer and cold in the winter. My use for the socks is "everything." With non-waterproof hiking/running shoes, Gore-Tex hiking shoes, Insulated Gore-Tex boots, uninsulated leather steel-toe work boots, western boots, Rubber-soled, felt-lined pac boots, etc.
What other brands/models have you had luck with?
