I'm looking for a recommendation for a good quality brand of socks. I figure that if I'm spending upwards of $500 for a pair of shoes, it makes sense to have socks that will help me maximize the pleasure of the experience of wearing the shoes. I like plain black, calf-length socks, so quality and durability are the most important concerns (as opposed to design). Also, I prefer lighter weight socks since my feet seem to get too warm in heavier ones. Seperate recommendations in the moderate and expensive price ranges would be appreciated (use your own judgement as regards to what would be considered moderate). Thanks!
