I love my Smartwool socks. There are no other pair of sock more comfortable, warm, durable, and (and maybe a stretch) good looking. The pair of Hiking Medium Crew socks I bought have never let me down and show no inclination of doing so. Get a pair at the Smartwool website or at Backcountry.
For a less technical sock check out these 'Solmate Socks'. (Via Cold Splinters)
