If I may: Smartwool has provided me with incredible comfort, reduced sweat and smell, and ample warmth on many occasions.
For what it's worth, though, Darn Tough Vermont was recently awarded Team Soldier Certification for their wool sock (full article:

I believe you can procure the socks through ADS Inc which, if you aren't privvy with, offers a nice discount to .mil/.gov/leo individuals on a broad range of items due to their massive purchasing power. I highly suggest you sign up for the MILITARY account so you can gain FULL access to their catalog, not just the civilian catalog.
