Warm socks for winter and cold weather – buying advice or what to consider
There are some really important factors to consider when choosing the right winter and cold-weather socks for you. Don’t worry, we’ve tried to organize them carefully so that everything sounds logical, and learning it is a no-brainer. We’d like to begin with the key objective factors. Then, we’d point out the critical subjective factors for choosing winter socks.
Materials
One of the most important factors when choosing a pair of winter socks is the fabric it’s made of. If you’d remember no more than three rules, try to remember these:
#1 Forget about cotton
Cotton is an excellent fiber that has many different applications but it is not a good option for winter socks. In a previous post, we compared cotton with polyester and pointed out the differences between these two fibers. Basically, cotton absorbs a lot of moisture, and when wet it feels cold and clammy. Once wet, cotton takes ages to dry. Moreover, wet cotton loses its insulation abilities and ceases to provide insulation, which might be highly dangerous in cold conditions. Wet cotton also wrinkles easily and softens the skin, which increases the likelihood of the formation of hot spots and blisters. In short, forget about cotton.
#2 Merino wool rocks
A crash course in merino wool:
- Probably the most popular type of sheep’s wool used in the outdoors industry.
- Generally, finer, softer, more comfortable, and retains its shape longer than traditional wool.
- There are different grades of merino wool fineness from 17 to 25 μm – superfine to strong respectively. The superfine merino has a soft texture similar to cashmere.
- Wicks moisture and transports it to the outer side of the garment so that it could evaporate. This way, the wearer of a merino wool garment might not even feel wet.
- Provides lightweight insulation allowing body heat retention. Moreover, merino feels warm even when wet.
- Dries relatively fast in comparison to other popular natural fibers such as cotton.
- Merino is naturally antimicrobial and is much more resistant than most fibers to odor-causing bacteria.
- Has no-itch properties that make it much less likely than traditional wool to irritate the skin.
- Merino wool has many positive characteristics of synthetic fibers that make them suitable for sportswear and activewear.
- Blends well with various man-made materials for increased functionality (durability, moisture management, thermoregulation, elasticity, etc.).
- Merino wool is considered one of the luxury yarns. It’s more expensive than other typical fibers used for making winter and cold weather socks such as traditional wool, and cotton or basic synthetic fibers such as polyester, nylon, acrylic, polypropylene, and elastane.
All these characteristics and properties have made merino wool one of the most sought-after materials for socks, gloves, and garments worn close to the body.

#3 Synthetics are used for improved functionality
While “functionality” often sounds too vague, in the case of winter socks it could be defined easily:
functionality = durability + wear and tear resistance + insulation + moisture management properties + lower weight + elasticity – shrinkage – pilling
Man-made fabrics and materials are quite popular among manufacturers of winter socks because they are modified to meet the specific requirements of the wearer. For example, polyester and nylon are famous for their durability and high abrasion resistance. Acrylic is lightweight and has a wool-like feel, whereas polypropylene (olefin) is tough and flexible and remains dry while transporting moisture (just like polyester). Spandex (elastane or Lycra) is used because of its exceptional elasticity and good recovery properties. While man-made materials have many positive characteristics, they do not come without disadvantages. Some of these disadvantages include odor retention (polyester, polypropylene), poor elasticity, pilling (nylon and polyester), low melting point, heat shrinkage, fibrillation (acrylic), poor dimensional stability or elongation at break, etc.
Note that there are various merino and synthetic blends with different wool/synthetics ratios. The manufacturer might have a ton of reasons for manufacturing a particular blend – from lowering the costs to achieving better functionality such as increased durability, insulation, elasticity, etc. So more merino does not always mean a better quality product. Higher merino wool content, for instance, means a softer and warmer but also less durable garment. Similarly, less merino content does not always mean a poor-quality product.
Cushioning
Winter socks serve a crucial role in keeping our feet warm and comfortable. Their tightly woven design provides ample support, ample cushioning, and a soft feel against the skin. This is important because, in addition to keeping our feet warm, socks also play a role in reducing friction between the foot and the inside of our boots. Typically, high-quality socks have different densities of material at different points for more cushioning or warmth or both. Such points with added cushioning are often heels and soles. The density of the fabric within the sock plays a crucial role in the protection of the foot. The extra padding also makes the socks warmer, more comfortable, and reduces the chances of blister formation.
Thickness and warmth
In most cases, there is a strong connection between overall sock thickness and warmth. For winter and especially for extreme cold, heavyweight socks almost always provide more warmth than their lighter counterparts. It’s the same with the cushioning as thick soles are cushier than the lightweight versions. Keep in mind that heavy thickness does not always translate into warmer socks though. There are quite too many examples of thick and heavy socks that failed to insulate well when they were expected to do so. It’s no coincidence that many experienced outdoorsmen prefer wearing two or three pairs of socks inside the boot. Such combinations (a thin synthetic inner layer underneath a merino blend outer layer is classic) reduce the incidence of blisters compared to single-layer sock systems.
Sock height
Many people consider this factor as not-so-important but often wearing the sock with the right height could literally make or break your experience. 
Here are the most popular types of sock heights (the figure to the right comes from Darn Tough and is included for easy reference; keep in mind that sock sizing can vary significantly among manufacturers):
Micro (mini) crew
Not a very good choice for winter, the micro crew is usually preferred for warm weather. Nonetheless, some models such as the Darn Tough Hiker Micro Crew Cushion are great examples of functionality and comfort. However, this length is quite short for cold weather conditions and we do not recommend it for winter.
Crew
Probably the most common height for socks, the crew also known as ‘lower calf’ (as it ends just below the calf muscle) is a standard height used for all-year-round socks for universal applications. It’s the optimal height for most environments and conditions, which makes it a great option for year-round socks. Keep in mind that it may not be so great for high-intensity cold weather activities such as climbing or skiing. Nevertheless, there are some great models suitable not only for socks for casual use in the cold but also for pursuits where high performance is required.
Boot height and mid-calf
The height of boot socks is somewhere between lower and mid-calf but it’s a bit closer to mid-calf. Many backpackers prefer socks with this height as it somewhat combines well with both hiking shoes and boots. Hunters, backpackers, and professionals from different areas wear mid-calf socks mainly with boots.
Over the calf+
Over-the-calf and knee-length socks rise to (at least) just below the knee. This length is typical for some types of sports socks such as ski (Smartwool Ski Full Cushion OTC), football (soccer), endurance running, and mountaineering socks. Compression and elasticity in the leg or at the top of the sock are important for the over-the-calf design because they keep the legs from sagging and slipping down and may have clinical and performance benefits for some people. Darn Tough Mountaineering OTC Heavyweight is a good example of a tough, warm, and comfortable heavy-padded sock suited for various sports and activities. Another great example is the winner for best waterproof cold weather socks – Sealskinz Waterproof Cold Weather Knee – fully waterproof heavy-duty knee-high socks designed to effectively block out any liquid for nice and dry feet in wet conditions.
Price
The prices for good winter socks vary quite a lot – from less than $10 to more than $30 a pair. The main factors behind this disparity include:
- Brand awareness and popularity – Darn Tough, Smartwool, Helly Hansen, and Farm to Feet are renowned as manufacturers of great socks, which means that many consumers are prepared to pay a premium for their products.
- Features – more technical features usually translate into a higher price.
- Materials and the quality/quantity of insulation used. The utilization of high-tech fibers and yarns such as merino and alpaca wool, and modified polyester fibers (COOLMAX, Thermolite, Hollofil) is more expensive than the use of other fibers like acrylic, polyester, and nylon.
- Product lifetime and warranties – the longer the useful life of a pair of socks, the higher its price.
While the factors above are more or less objective, some of the most important factors are subjective ones. Here’s what you need to know about three of them.
Durability
There is a huge difference between sturdy winter socks built to last for ages and flimsy constructions that won’t survive their first use. Manufacturers use mainly synthetic fibers such as polyester and nylon for reinforcing their constructions. Many popular and not-so-popular companies make socks that hold up fairly well. By this, we mean that good socks can last at least a couple of seasons if properly treated. Nevertheless, Darn Tough are still a mile ahead. Simply, their socks such as the overall winner Darn Tough Hiker Boot Full Cushion are a symbol of toughness.
Comfort
The perception of the presence or absence of comfort is strictly individual. Comfort depends on fit, sock materials, breathability, price, i.e. on everything that contributes to the overall experience. No single manufacturer makes the most comfortable socks. Some people prefer Smartwool while others swear by Darn Tough or Fox River. Sometimes comfort is brand specific but more often than not, it isn’t as there are often differences in the level of comfort among different models and designs made by the same manufacturer.

Various winter sock warranties
Unfortunately, this is not always an objective factor as different manufacturers have established different policies related to the warranties they offer. For example, Darn Tough offer an unconditional lifetime guarantee for its clients from the US (apparently, the warranty policies for internationals differ). Others such as Farm to Feet offer a satisfaction guarantee so that if you aren’t completely satisfied with the durability or performance of your socks, you can return them for a replacement pair or a refund (with proof of purchase). Smartwool’s warranty policy is very similar to this but it comes with a set timeframe of 2 years. Other companies offer more limited policies like the standard 30 or 60-day return policy.
Generally, be careful when you see something such as a “lifetime guarantee” or “lifetime warranty” or “2 years guarantee”, etc. Often, in order to be eligible for a replacement pair or a refund, you must satisfy certain conditions.
Conclusion
The socks marketplace is a highly competitive field filled with good products. When looking for winter and cold weather socks, look for socks that are comfortable, fit well, cushion feet, reduce abrasion from your footwear, have decent moisture management properties, and can ensure proper thermoregulation for the feet.
