While on the subject, get some de-scaled wool socks as well. Cool in summer and warm in winter. More comfortable than cotton and they don't hold moisture. Smartwool is among the best I've used. I use them for everyday around the house, cycling, half marathons and 10k road races. Great stuff.
Darn Tuff (Tough?) socks are pretty good too, and have a lifetime warranty. Smartwool is a touch better though.
I switched to the smartwool sock for field problems. My feet would sweat in the middle of winter they were so warm!
