I have feet that sweat profusely. I typically just wear a heavy pair of wool socks and my rubber boots. If I know I'm going to be in snow and feet will get cold- I'll put some toe warmers on the inside. I do have a pair of insulated rubber boots, and I like them, but they make my feet sweat bad.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
