There are many unique tricks to keeping your feet wam in winter. Sometimes it takes awhile to learn all the tricks and experimentation and to get the best boot combinations for the cold winter months. It is a balancing act because everyone seems to have a different temperature that they like . Everyone seems to like their feet a different level of warmth too. Most people do not believe it but wearing a warm hat helps keep the feet warm. LOLOL That is the first step,our heads are like chimneys and if we do not wear a hat our bodies cool off fast and our extremities get cold first.I can't remember for sure but I believe the experts say we lose about 60% of our body heat through our heads.
You need to assess the weather you are going to be in and dress for the weather conditions. You are going to need to keep the feet dry first. That is covered in another Guide under the moccasin topic.Keeping your Feet Dry.
You need to adjust the shoe or boot linings to the type of heat you are going to be in. If you insulated the feet with a gortex stocking,smart wool sock or felt pack and go into a warm building before going out your feet are feet are going to be regardless of what the advertising says, wet! Wet with sweat and this will cool them down as soon as you spend any time at all out in the elements.Most modern boot linings will help if the boots or mocassins do not fit to tightly.There must be room to wick that moisture away from the feet.
You need a bit of space between the foot and moccasin to provide air space. You can fill this space with a nice
wool seamless smart sock and change the insulation if the need arises. Most oldtimers layered their feet as well as their bodies.If their feet got wet,they removed the wet moccasins and replaced them with dry pair or they carried extra wool socks. Wool socks were the best for this because they can be wet and still warm. They also dry quickly near a fire. In the early lumber camps, and hunting camps the old stand by were the felt packs and insoles, and wool socks.I think a smart sock, a gore tex sock, or felt pack and insole is the best lining you can put in a boot or moccasin. In that order. There is nothing more comfortable than a pair of mens or womens moosehide moccasins and a good seamless smart sock footie, hmmmmmmm your feet have died and went to heaven without you again!!!! HAPPY,HAPPY FEET!

I can remember growing up in a Grandma Anna's Deer Hunting camp in Dublin Michigan this November time of year when it would rain and snow, and you would get those wet,snow,rain dripping falling off the trees days.  The hunters would take off their felt packs and hang them on a special rack designed behined and near the old wood stove.When Grampa Gillispie would fire her up you would see the felt packs begin to steam. Believe me you didn't need a humidifier in that bunkhouse that night to keep the air from getting dry. That is probably one of the reasons the hunters called it the Bunk House of Unusual Odors. Actually it wasn't that bad,nice childhood memories.Woodstove,hunters stories,fellowship,laughter,good bourbon,Vernors Ginger Ale,and the" Scent " of just men, just enjoying life.
Folks,there is nothing better for winter comfort than a gor-tex sock,or a smart wool sock in a good hide moccasin for wear winter. Second best is the old style ugly felt pack and insole to keep your feet warm and toasty in the winter. I like the layers again of 1# wool smart sock,2#gore tex sock,3#Felt pack/insole. Then I am ready to go into the woods.Woops I forgot the boot or mocassin! 4#Boot or moccasin.You really don't need them now just for the tread.   LOLOLOLOL

My Dad was a Lumberjack part of his life and he learned how to dress for winter in the Lumber Camps, he liked a felt pack with regular arctic black rubber buckle boots. If they got too hot he would unbuckle the tops inside and let then vent for awhile then close them up before going outside. They had a nice tread and the combination was light to wear, unlike those Big White Blow up Air Force Boots! Which are extremely warm by the way. I'll bet a good modern combination would be artic rubber boots with a smart sock,or gor-tex liner!
Actually I really like the combination of a Gortex sock or smart sock and my Ojibwe style hunting boot for outdoor/indoor winter all around. For a real treat try these Ojibwa Hunting style boots and a Gortex sock! WOW
prize winning combination!

                                     

You have to be very cautious when walking on the snow or ice but I like the feel of the earth on my feet when I walk.! You really need a boot with tread to keep from breaking your legs and pelvis like my Brother in Law, Phil, use boots with the following tread if you are going to be doing much walking outside on the snow and ice.
