Men's Extreme Cold Socks

Tested in The Toughest Conditions

Loved by snowmobile and dog sled racers, trusted by Canadian construction workers and Lake Superior ice fisherman, Thorlos padded Extreme Cold weather socks are the choice for those who play or work long hours in the cold. Alpaca socks – known for their warmth - are no match for our highly protective worsted wool-THOR-LON® blend over-the-calf padded socks.

Allergic to Wool? We recommend our Hunting Cold weather padded sock, which does not contain any wool. Click this link to see and read about the product.

“Socks, like other important gear, can make or break a day of ice-fishing or hunting deer. These socks allow me to put on just one pair and stay warm. I like them so much; I gave a pair to a trapper friend of mine, a bird hunter friend of mine, and my brother in northern Wisconsin. Each of them has thanked me several times and have inquired about how to order more.”  John F.


Built for Warmth and Comfort

Thorlos Extreme Cold Weather socks have been constructed to:

            Keep your feet warm…

Keeping your feet warm in frigid conditions requires the right thermal fabric. Wool for warmth is a given, but not 100% worsted wool. In a well-insulated boot, your feet will perspire. To keep them warm, it’s absolutely essential to blend the wool with our proprietary THOR-LON yarn; the blended fabric wicks perspiration away, keeping feet dry (and the skin of the feet healthier) during 8 to 10 hour days. Dry feet are warm feet. If your feet get wet, they will get cold more easily, which can start a chain reaction that  chills your entire body, causing you to shorten your work or play day and possibly putting your health (or life) at risk.

            Stay up all day long…

Out in the cold you need socks that will stay up over your calves all day long. If you’re wearing gloves and protective pants, you’re unlikely to be able to tug your socks up during the day. That’s why Thorlos Extreme Cold weather padded socks are made with a 4-inch long ribbed spandex knit secure-fit top. The top snugs comfortably to your calf, staying in place all day long.

            Keep your feet and legs comfortable…

Thorlos Extreme Cold weather padded socks are made with our engineered clinically-tested padding placed exactly where you need it. As always, you’ll find padding on the balls and the heel of your feet. It’s also been added where your feet require protection from your boots. You’ll find Thorlos clinically-tested padding across the top of the toes for protection and thermal insulation, across the top of the feet, around the ankles and all the way up the front of your legs to protect and insulate your shin.

All of this padding translates into:

-          blister reduction

-          pressure-point protection

-          more effective wicking of foot perspiration

And this translates into Profound Comfort®.


“Best socks I wore in my life, recommend for those who want high-quality socks really - really worth every penny. Not only are these warm blister free socks, they really support ankle & calves muscles. The double thick layer running up the shin is wonderful, as well as everything else about this sock. We have several different types of Thorlo Socks, but this is the one for cold weather motorcycling.” Mona P.


“The title say it all - great socks for warmth and comfort.”  Randy B.


“Besides being very warm for my cold feet in winter, they are super soft and comfortable.”  James H


“I just love these. All of the cushioning is great and in the right places.”  Elizabeth B.

    nice winter-weight sock

    These are a very nice, thick sock, with good padding. They are a bit itchier than other styles, however, and are not as long as some - don't cover the knee. Overall, however, they are quite warm for winter. And Thor-los do last a long time!

    Couldn't find a better pair of socks anywhere.

    Quite simply, I haven't purchased socks from anywhere but Thorlo since my first pair from you folks. That was about 4 years ago and I have no intention of changing my buying habits with regard to socks. Great product that I feel has no equal. Thank you so much!

    Best socks ever! I can't stress that enough. I've spent years and hundreds of dollars on other brands promising the same thing, but Thorlo actually delivers! These are my go to socks from here on out!

    My husband and I bought these socks for playing golf in the New Jersey winter when the ground is hard and frozen. We have always worn heavy Thorlos but nothing can compare to the warmth and comfort of the EXCOU!
