My feet sweat terribly even when I am not hiking into my stand. I now spray my feet with a powder antiperspirant before donning silk socks and then a pair of alpaca wool socks. I can't seem to walk in rubber boots as they don't provide enough support for me, and i don't have to cross any creeks where I hunt. I wear LaCross pack boots with removable liners, and bring a pair of boot blankets for long cold sits in a stand. I always have a square of 3/4" foam insulation to put my feet on when in a tree stand. Learned that years ago as a field surveyor and had to stand for long hours behind the survey instrument on cold pavement.
