Query: Best socks on the market

I just purchased four pairs of Thorlo Men's Hiker socks. I last purchased four pairs of the same socks more than two years ago and finally have to replace them. In my experience, doing a lot of city walking and trail hiking, these socks last the longest and retain their cushion for many miles. They also hold up well in the wash and require no special care. Really, these are the best quality socks on the market. Add in the fact that they are made in North Carolina, so you're helping the local economy and can feel good about this purchase. One note about sizing, these socks run on the large size--I usually wear a men's size 9.0 shoe, but prefer the medium size of this sock.
