If you're going to spend all day in the woods, you're going to need a sock that can stand up to abuse and that'll keep you warm while you wait for your game to show up. Smartwool included extra heavy cushioning in the leg and foot of the Hunt Extra Heavy Crew Sock, exactly for those reasons. A flat knit toe seam makes sure you won't experience any sort of rubbing, no matter how long you find yourself wearing these socks. The proprietary WOW technology involves putting more wool into the high impact areas of the sock. This means more comfort, and more durability. More is better.
