Then we have the feet. They are important for a number of reasons, especially walking. And if they get cold, your whole body will feel uncomfortable and after a while you will freeze all over. So, how to dress your feet. First use a thin wool sock, then a thicker wool sock. I only use wool on my feet. Since the feet are crammed in a quite tight place, where moisture have little chance of escaping wool is the number 1 choice since it got the ability to keep warm even if its somewhat wet. So my advice is to leave your cotton and polyester socks at home. Your boots may need some adjustment too. The inner sole of your boot may be great for forming after your foot, but they might not insulate good enough from the cold ground. I buy boots a half or one size bigger than my feet, so i can insert a wool sole inside, approximately 7,5 millimeter thick. They might be possible to buy, but i make my own from an old wool carpet I have had for decades. This is what I use in my hiking and cross-country shoes. This works great for me, i rarely get cold feet, even when it`s down to -25 C. But, there is a but, if you get really wet on your feet, you will get cold. So always have extra socks in your backpack. This is paramount. Here comes a survival tip. Change to dry socks as soon as possible and if your boots are wet, which they probably are if your socks are, have a couple of plastic bags in your backpack, pull them on outside your socks and put on the wet boots. This way your new socks won’t get wet and cold. Wear it till you get the chance to dry your boots.
We are still not finished with clothing, now we go to extremities. They are very important to look after. They get cold the fastest, and when they do, things quickly get harder to do. Its not only the freezing it self that’s bad, its also that you lose feeling in what you do. For example, when your fingers get really cold, simple things like packing your backpack can seem almost impossible. It hurts and you lose your strength. So we start with the mittens. I use a double layer mitten, they usually come with a fleece inner layer and a polyester outer layer. They work fine, but I replace the inner layer with a thicker wool mitten. Call me old fashioned, but I think wool works better if they get a little wet. The outer layer is also good to use with gloves inside. The reason for the double layer is that you can remove the outer layer and have better movement and feeling in the hand for setting up a tent or cooking. I also recommend an outer mitten with an elastic band lanyard, so when you take them off they won’t get lost.
