I can generally stand cold weather. But, if my feet get cold and wet then I am miserable and have a hard time staying still. The last few years i've gotten rid of the thick socks and just wear poly or something similar, and I take an extra pair in the field with me if I am going to be there for more than a few hours especially if I have a long walk. Putting on a pair of nice, dry socks has made a world of difference for me. At times I even switch boots during the day. (my feet usually aren't wet from rain etc, but from sweat).
