Get an extra pair of liners, and alternate them each day.

Buy a couple pair of good wool socks. Smart Wool is a good brand (I believe it's actually a wool synthetic blend). That same website sells Smart Wool socks, as do many other places.

The boots need to be loose enough so that you can move your toes around. A tight boot or too many socks may seem like a good idea, but it just reduces blood flow to your toes. Buy your normal size (or maybe 1/2 size large), and wear a single sock. Some guys use sock liners; very thin socks designed to wick moisture away from your feet. I've never thought they did much good. YMMV.

Neither of these make for a good active boot. The first is too heavy, and the second gives you little support. If you're gonna be active (not sitting in a stand), you need a far less warm boot, and I'd look for more of a traditional hunting/hiking boot.
