I'm tossing out all my cotton & poly dress socks. After wearing my "snowflake" smartwool socks to work I few times, I found that I don't come home w/soaking wet feet (I admit it: my feet sweat a lot!). Rei has a great deal going on now -- 10% off if you buy 3 or more pairs of socks. Stocked up on some smartwool socks that I can wear w/slacks to work.
