Bass... Sorry bud, just saw this post today.
Polartec socks from LL Bean or Lands End will do the trick. Really isn't too much difference in them and how warm they are. Trust me, they will feel quite warm compared to other socks you have. And your feet will sweat a lot, and not wick the way composite fabrics do. It's the nature of the beast though.
And BTW, even though you'll sweat, I have never had my feet get cold as a byproduct of that.
