Hunting / Ice Fishing Socks
The same sock principals apply to hunting and ice fishing. You want a sock that will keep you warm and keep moisture at bay.
With hunting you’ll be hiking a lot, so you may want to consider a thinner sock. However, if you’re ice fishing- you’ll be sitting or standing in one place.
This type of activity probably lends itself to a thicker sock, with more insulation. Let’s take a look at what the best socks on the market today are designed for extreme cold hunting and ice fishing.

What to Look for in Extreme Cold Weather Socks
Did you know your feet are like thermostats for your body? If your feet are warm, then you’re typically feeling pretty cozy everywhere else.
But, when your feet are cold and wet, you start to feel it in your legs, chest, arms and hands.
When heading out into the extreme cold you want to choose the best sock for your activity. You also need to pay attention to the fabric of the socks.
We’ll get into all these tips in more detail below. Other things to consider when choosing the best sock for extreme cold: thickness, padding and fit.
Best Sock Material for Extreme Cold
Let me start this section by making it very clear you should without a doubt stay away from cotton socks at all costs! Seriously, cotton kills, and you don’t want to die because of a poor choice in socks.
In all seriousness, cotton absorbs sweat and doesn’t let it go. Wearing cotton socks is like put a pair of sponges around your feet. You’d never do that- at least I hope you wouldn’t. When cotton socks absorb sweat, they get wet.
A few miles into a 30-mile winter expedition and your feet are soaking wet.
You can thank cotton for that. When your feet are wet, you get cold! And it’s not just your feet that are chilled, suddenly your entire body is shivering and you’re entering the beginning stages of hypothermia.
I know it’s a bit dramatic, but this is a very real scenario you could face when you choose the wrong socks.
So, what should you be wearing? Great question. You want to look for socks made out of synthetic material or merino wool.
I’m partial to merino wool, simply because they are exceptionally soft and incredibly functional. Merino wool wicks away moisture, preventing your feet from getting sweating.
Merino wool is also a great choice for insulation- keeping your feet warm, but not too warm.
Synthetic socks are made out of nylon, Lycra and other man-made materials. Synthetic socks are a great choice too!
This type of material also wicks away moisture all while keeping your feet warm and dry. Your biggest objective when choosing the warmest sock for extreme weather is to make sure they keep moisture away.
If your feet stay dry then you will stay warm!
Warm Socks = Warm Feet
Wherever your next adventure takes you, choosing the right pair of socks will determine how much fun you have! No one likes to hunt, hike or ski in wet, cold, socks.
How many times have you called it a day because of chilly feet? Too many to count.
With so many innovative fabric blends at a variety of price points, there is no reason not to have warm dry feet on your next adventure in the extreme cold!
