Wool socks are warm and they also absorb moisture.
Be sure you can wiggle your toes in your boots to keep circulation moving. Keep your boots looser than normal to aid circulation. YOUR BODY will be warmer if you do some exercises before you get on the lift and immediately after you get off the lift. Jump up and down. Swing your arms.
