Looking for a great pair of winter socks?

You’re in the right place! In this guide, we will be covering the following:

    • The top materials for winter socks
    • What features to look for in warm socks
    • Reviews of 5 of the best winter socks
    • Our unbiased conclusion on the best pair of socks to keep your toes warm

As a serious hiker, you know your hiking shoes are your most important piece of equipment. Your socks come a close second. Why are they so important?

First, the right type of sock prevents blisters. Second, they cushion your feet to keep them comfortable over rough terrain. Finally, keeping your feet warm and dry and absorb odors.

We’ll examine these parameters in further detail below as we help you find the best warm sock for your needs.

The Most Important Properties of Winter Socks

There are three main factors to consider when buying winter socks for cold-weather hikes.

Warmth

The ideal winter socks will keep your feet warm during cold weather hikes without overheating. You want an insulating material that will trap your body’s heat while removing moisture.

Some fibers, such as merino wool, are thermostatic. That means they regulate heat. Air pockets in the fiber keep you warm but allow your feet to breathe. Thus keeping your feet and toes at an optimal temperature. You won’t need to layer your socks, like some hikers, to regulate the heat level.

Of course, if you go with self-heating electric socks, you will be able to adjust the temperature easily. For people with circulatory issues or conditions such as hypothyroidism, these types of winter socks may be a great option since you won’t need to rely on your body’s ability to generate heat.

Wicking

Good hiking socks wick moisture away from your feet and toes. The way this works is through a process called capillary action. The socks don’t absorb moisture; they allow it to travel via tiny conduits along the fabric and away from your skin. Once the moisture reaches the outer layers of the sock, it evaporates, keeping you dry.

Intelligent designers use naturally wicking materials combined with features such as ventilation channels to optimize a sock’s wicking properties. Additional features like mesh construction can increase breathability.

Comfort

Your winter socks must fit well to do their job. They should be snug and slightly taller than your hiking boots to protect your calves from chafing, and should be form-fitting without binding.

If the fit is too loose, the winter socks can bunch up or wrinkle, leading to blisters. On the other hand, winter socks that are too tight can cause pressure points, cramps, or even numbness.

Other factors related to comfort are cushion level and how the socks feel against your skin. You want socks that buffer your feet on rough terrain and that aren’t abrasive against bare skin.

Below we discuss the variety of materials you can find in hiking socks and how they satisfy the requirements of warmth, wicking, and comfort.

The Best Sock Materials for Extreme Cold

Socks come in a variety of fabrics. While some of them, such as cotton, are fine for wearing around the house, they are not great winter socks to wear for hiking. Below we’ll give you the rundown on a variety of fabric options.

Cotton

Cotton feels soft, is inexpensive and easy to layer. When it’s dry, its air pockets provide insulation. When you exercise, however, it absorbs water and loses its ability to keep you warm. Therefore, cotton socks are a terrible choice for hiking in cold weather.

Merino Wool

Merino wool, on the other hand, is one of the best options. Wool fibers crimp, creating air pockets to provide insulation. The crimps also act like springs, making wool elastic. It can stretch and bounce back. This helps wool socks fit well.

Because wool repels water, it wicks sweat away from your feet and provides some rain protection. But even soaked, wool does a better job keeping you warm than many other materials.

Wool is also anti-microbial. It has an organic acid called creatine that breaks down odor-causing bacteria, so your feet won’t stink when you wear wool socks.

Unfortunately, wool can be itchy. The coarser the yarn, the more abrasive it will be. This coarseness is measured in microns, which are a thousandth of a millimeter. Most wool is between 28-33 microns in thickness. Merino wool, however, is under 22 microns. Because it is so much finer than other wool, most people find it soft against even bare skin.

Cashmere

Cashmere is a luxury fiber derived from cashmere goats. Typically under 17 microns, it is softer than wool. It is also three times warmer and wicks moisture to keep you dry.

Unfortunately, cashmere is delicate. It pills easily, and it’s not elastic. Cashmere drapes instead of fitting snugly. That makes it a lousy choice for winter socks, but an excellent choice for scarves.

Synthetics

Some synthetic fibers used to make moisture-wicking socks include acrylic, polyester, nylon, and spandex.

None of these absorb water, so they are great at wicking moisture. Acrylic and polyester also provide warmth. Polyester is used to make fabrics like Polarfleece. Acrylic can be used as a wool alternative and, like wool, fights odor.

Nylon, along with Lycra spandex are not warm but provide elasticity. They can be blended with warm materials to give socks a snug fit and arch support.

Exotic

Alpaca, bison, and yak are luxury fibers. Like cashmere, they are warmer than merino wool but lack elasticity. They need to be blended with other materials to make socks. Unfortunately, they also tend to be expensive and less durable than merino wool or synthetics.

These alpaca blend socks are a great choice if you wear taller hiking boots since they provide knee-high coverage. That means the backs of your boots won’t chafe bare skin. Additionally, a pair of socks made from Alpaca are warmer than a similar pair made of merino wool, making this an excellent choice for freezing temperatures.

Like merino wool, the alpaca in this blend wicks moisture and has anti-microbial properties. These socks will keep you dry all day and not stink when you take off your boots by the campfire.

Another advantage of alpaca is that it’s hypoallergenic. These socks won’t itch even sensitive skin. However, while alpaca is also softer and warmer than merino wool, it’s not elastic. Lycra spandex and a wide rib help these socks to fit correctly. They will even stretch over bulky calves.

  • PROs

    • Stretches to fit larger calves
    • Alpaca is hypoallergenic

  • Durable and Comfortable Socks By Smartwool
  • Merino Wool
  • Over The Calf
  • WOW Technology
  • Ribbed Leg

These merino wool socks are amazing. Because merino is such an excellent insulator, these are among the warmest socks in cold weather, but will still be comfortable when it warms up. That makes them a tremendous three-season sock that you can wear on all but the hottest days. They will keep your feet dry no matter the weather, thanks to the water repellent qualities of merino. The merino wool also keeps your feet odor-free.

The socks come with cushioning for rough terrain and are elastic, so they’ll flex with your feet. They won’t bunch or sag, and they provide arch and ankle support. That makes them great for a variety of footwear, including hiking sandals, since they provide additional support as you navigate steep inclines.

On top of all these benefits, these socks are tough as iron. That makes them a great value since they will last you many seasons.

  • PROs

    • Keeps feet warm and dry
    • Odor and water-resistant
    • Cushioned for comfort
    • Light ankle and arch support
    • Won’t bunch or sag
    • Durable and tough

These socks contain a much higher proportion of merino wool than the Smartwool socks. That makes them warm, dry, and odor-free. Intelligent design features were added to increase their utility. For example, a mesh fabric supports your insteps while increasing the sock’s breathability. Terry-loop cushioning was added to help keep your feet comfy over rough terrain.

Because these socks are thinner, they might feel more comfortable and be an even better fit for all-season wear. The disadvantage to the more delicate fabric and the higher merino content is that it makes these socks less durable. They will pill more quickly than the Smartwool socks.

They are less expensive than other options and come in many colors and designs. Make sure to hand wash to keep the colors vibrant, though, as some of the dyes bleed.

  • PROs

    • Merino wool keeps your feet warm, dry and odor-free
    • Excellent value for the price
    • Cushioned for rugged terrain
    • Come in many colors
    • Great value
  • CONs

    • Not as durable
    • Some of the dyes bleed, so hand wash
Bottom-Line: These colorful and practical winter socks are a great value.

  • Electric Heated Socks-3.7v rechargeable battery to heat,warm accessories in…

If you suffer from circulatory issues or have a condition like hypothyroidism, these thermal socks might be the best winter socks for you. They might also be great for those with arthritis or anyone who likes gadgets.

They have carbon filaments that warms socks with a gentle heat when plugged into the rechargeable Lithium-ion batteries. Once turned on, they immediately warm up. The heat setting is adjustable to prevent overheating.

Made of smooth cotton, they are comfortable despite the sock warmer heating elements. Since the carbon fibers that provide heat are thin and the battery is unobtrusive, you will barely notice them. The battery slips into a small side pocket.

The most significant disadvantage (aside from the cotton) is that the battery lasts only 6.5 hours on the lowest setting and 3 hours on the warmest one. This then makes these a bad choice for a week-long backpacking trip. They are also relatively expensive.

  • PROs

    • Light and comfortable
    • Three warmth settings to keep your feet warm
    • Unobtrusive battery
  • CONs

    • Limited battery charge time
    • Somewhat expensive
Bottom-Line: These are a great pick if you need immediate heat or help to stay warm.

United by Blue Ultimate American Bison Sock

Most Comfortable

United By Blue Ultimate American Sock
  • 1×1 Spandex rib knit welt
  • Spandex knit throughout leg
  • Reinforced heel and toe areas
  • Spandex rib arch support
  • Flat knit side panels

These beautiful winter socks are made in the USA from native bison down. This is a luxury fiber that is considered softer and warmer than cashmere. Like merino wool, it is moisture-wicking and naturally cushions your feet and toes, so you feel you are walking on air. The bison is blended with merino and spandex to provide structure, and a spandex rib also offers arch support. Nevertheless, a pair of these socks is not very durable, so you might want to save them for lounging around the campfire.

If you decide to splurge and get yourself or a loved one these thick, warm, and super-soft socks as a special treat, you can feel good knowing you’re also helping the environment. United by Blue removes a pound of trash from the oceans for every pair sold.

  • PROs

    • Very warm and comfortable
    • Beautiful and luxurious
    • Extremely comfortable
    • Your purchase helps the environment
  • CONs

    • Expensive
    • Not durable
Bottom-Line: One of the best pair of socks to pamper yourself or a loved one with.
