There’s nothing like a cold winter morning, where the sun is shining bright and glistening off the ice drenched maple trees.  Enjoying the great outdoors in the middle of winter is exhilarating, but It can also be equally dangerous. 

What you wear and what your gear is made out of will essentially determine whether or not you survive the back-country snowmobile ride or summiting Mt. Rainier. And this includes your socks!

Best Socks for Extremely Cold Weather

Even if you’re just hitting the slopes for a few hours, you need to stay warm.  If you’re not wearing the proper clothing, and that includes socks, your body temperature is going to start dropping rapidly.  When you’re in extreme cold weather, it doesn’t take long for hypothermia to set in. 

Sit back and read and I will give you my pick of the best socks for extreme cold!

11 Best Socks for Extreme Cold

Okay.  Now that you know what to look for in a pair of warm winter socks, let’s take a look at what’s on the market today.  Remember, we don’t want to our feet to get too hot or too cold, so you need to take into consideration your activity level when you’ll be wearing a particular pair of socks – you also need to make sure you have some decent winter boots

With the gear nowadays, you can pretty much do any activity outside in extreme cold.  With that said, I’m going to narrow down the best socks for extreme weather based on activity. Let’s get started.

Skiing Socks

Okay so these first four socks are the ones for snow skiing. You can use them for other things but skiing is primarily what they were designed for.

1. Darn Tough Men’s Padded Cushion Skiing Socks

Are you ready to make fresh tracks? Slip on a pair of Darn Tough ski socks and you’ll be the last to lodge for a cup of cocoa. These socks are padded in all the right places and made with all the right material to keep you nice and dry, even when you wipe out on that double diamond run.   These socks are made out of 62% merino wool, 4% Lycra and 34 % nylon.

The right combination of wool and synthetic material makes this a top choice.  The Lycra keeps the sock in place- preventing you from reach down your ski boot to pull up a rouge sock.  With a lifetime guarantee this may be the only pair of socks you’ll ever need for skiing in extreme cold. This sock is also thin, which keeps the circulation flowing in your foot.  Stay away from thicker socks, especially when wearing ski boots!

Mountain Climbing / Hiking Socks

So, you’re getting ready to summit Mt. Rainier and you’re in the market for a new pair of socks.  You’ve come to the right place.  When your mountain climbing, you will be exposed to extreme cold temperatures, especially the higher up you go.  You need to keep your toes warm when you summit and descend off that mountain.

This pair of socks are a little thicker than the previous SmartWool sock I mentioned above.  So, you’ll want to try on your socks with your boots to make sure it’s a good fit.  You don’t want your feet to be too snug in your boots, otherwise you’re losing circulation.

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. If you are sitting down a lot, our article on how to keep you feet warm while sitting still in winter would be a useful read.

9. Darn Tough Extra Cushion Socks

They don’t slip, slouch or shift in your boot.

That Lycra plays a critical role in sealing out the weather at the top of the sock.  It’s fits like a glove, too! Not too tight and not too loose.  It’s the perfect sock to keep out extreme weather conditions.  I know I sound like a broken record, but this sock is a top pick for keeping your feet warm in extreme cold.

Snowmobiling Socks

Writing this article is really getting me itching to get out in the cold winter mountains, particularly on a snowmobile. Snowmobiling is one thing that it has been a really long time since I have done personally. But I digress.

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!
