indigenous peoples solved this problem LONG before modern technology came along to screw up everybody's feet and keep them on a treadmill of shopping for answers. the solution is breathable mukluks. people think the solution to warm, dry feet is to build more and more layers against the cold, heavier boots, rubber, etc. but all that does is to trap the water and if you walk in any boots long enough, eventually the perspiration builds up and you get cold feet.
i'm one of them there skinny, lanky fellers with a very high metabolism - if i don't have food in my belly, i get cold. my feet and hands are almost ALWAYS cold if it isn't really warm out. and my feet seem to be sweating ALL THE TIME. i have tried countless numbers of boots trying to keep my feet warm. and btw, i live remote, at the end of a long dirt road at 8500 feet in the mountains, i work from home, so i'm rambling in the wilderness EVERY DAY, all four seasons - point being, I HAD TO FIND SOMETHING THAT WORKS. and i did...
"empire canvas works" (at the URL of the same name) is a little cottage industry company run by a couple up in wisconsin, i think, that makes clothing from natural fibers designed for really cold weather...i bought some of their "true north boots" about ten years ago... these are sort of a modern version of mukluks, made from bison leather, cotton canvas and wool inserts - my feet are TOASTY in these things with just a pair of lightweight wool socks in SUB-ZERO weather. the key is the loft of the wool and the fact that it wicks away your perspiration and allows it to evaporate through the cotton outer layer. my feet are NEVER wet in these things and ALWAYS warm.
(i have no vested interest in this company - i'm just a HUGE fan of their stuff cuz it's the kind of handmade "good honest folks" quality i really appreciate - stuff built to last a lifetime.)
the DRAWBACK, however, is that if there's snow on the ground, the weather has to be well under freezing - otherwise the snow is gonna' melt and soak through the cotton and leather which will obviously result in very cold, wet feet... and they ain't cheap - but that's how it goes when your clothes isn't made by third world slave labor and junk plasticky materials...
i know there are other companies making mukluk style stuff as well, but these are what i've found to work best for me... natural materials and breathability are the key... which pretty much go hand-in-hand because goretex-shmoretex, no one has come up with a "high-tech" fabric that beats the naturals on an all-around basis. not in my experience, anyway...
oh - the other "drawback" is that if you've messed your feet up with modern corporate-designed footwear and all the arch support and high-tech nonsense they build into shoes these days to make up for the problems caused by straying away from simplicity, you may need some time to adjust to having flat soles and no ankle support - and after that adjustment period, you'll realize you now have the most comfortable footwear you have ever owned and wish you could wear these all the time...
