Merino wool socks combine softness, durability, and year-round comfort, setting them apart from cotton and synthetic alternatives. Their fine fibers regulate temperature, wick away moisture, and resist odor, keeping feet comfortable in both hot and cold conditions. Blends with nylon or elastane add strength and stretch, making them ideal for everyday use and outdoor adventures.
Merino wool socks are a special piece of clothing, thanks to the comfort and functionality they combine. Our research aims to answer the age-old question: what are the best socks (and why are they made from Merino wool)?
The key difference between wool coming from Merino sheep and other materials is the texture. When you examine the Merino thread closely, you can see precisely how it functions as a finer, more absorbent alternative to its cotton or synthetic counterparts.
Unlike traditional wool, Merino fibers are much finer, measuring about one-third the diameter of human hair, making them exceptionally soft and non-itchy against the skin. This ultra-fine structure allows the fibers to bend and flex more easily, which translates into greater comfort for all-day wear.
Merino wool socks serve as a year-round solution. Their thermoregulatory properties help you stay comfortable through any weather change. Cotton socks are resistant to heat and cold, but to a lesser extent. They are ideal for spring and early summer, as well as milder days in the fall.
Moisture-wicking is another property shared by these two materials. However, Merino wool has superior absorption properties. Its hydrophilic texture means that it can increase up to 30% in size by retaining water - water that will stay far away from your feet. Cotton does protect you to a degree, but scorching summer heat will still let you feel soaked.
Not to mention that sweat buildup is responsible for numerous health complications, particularly when it comes to podiatric health. From bunions to fungal infection, sweating is the primary culprit.
So what Merino proposes is wearing healthy, comfy socks every season. Of course, sock thickness may vary as temperatures soar, but each version of Merino wool socks comes with the properties we grew to know and love.
Natural fibers like Merino have advantages over their synthetic counterparts as well. However, the best course of action is to combine the two fabrics and create socks that have the strength of both.
Synthetic socks are known for their lightweight and flexible feel, but they come with the risk of overheating. So, those thin socks you matched with your dress shoes will be a nightmare to wear in the summer.
The solution is to combine these two fibers into the perfect sock. Although you may believe that 100% Merino wool socks are the best option, mixing wool with a stretchier and more durable fabric can prolong the life of your socks. Plus, they will retain their shape longer.
Merino sheep provide top-quality wool, which is finer and more lightweight than traditional wools. Furthermore, you can wear it directly on your skin because it is not itchy. Itchiness is the primary complaint associated with traditional wool. A finer version of it will prevent these issues.
Moreover, Merino is hypoallergenic and will provide a comforting touch even to people with sensitive skin. Although it is fine, Merino sheep hair is not brittle. It is as durable as its traditional version, and even more so when reinforced with other materials.
A bit of history: The Merino breed originated in Spain several centuries ago and was so highly prized that, for hundreds of years, exporting the sheep was forbidden under penalty of death. This exclusivity made Merino wool a luxury reserved for royalty and the wealthy elite of Europe. By the 18th century, the sheep spread to Australia and New Zealand, where vast open pastures allowed them to thrive. Today, those regions remain world leaders in Merino wool production, combining centuries of tradition with modern techniques to deliver a fabric known for its unmatched softness, breathability, and durability.
In recent decades, Merino wool has gained renewed popularity across Europe, particularly among consumers seeking natural and sustainable alternatives to synthetics. Fashion houses in Italy and France have incorporated fine Merino wool into luxury garments, while socks brands in Germany, Switzerland, and the UK have adopted it for outdoor gear due to its thermoregulating and odor-resistant properties.
This premium fiber is exceptionally gentle on the skin, helps regulate temperature, and offers excellent moisture-wicking properties, making it ideal for both everyday wear and demanding outdoor conditions.
The material’s texture has kinks that trap dry air, which makes for a pleasant chill in the summer and comfortable warmth in the winter. This natural crimp in Merino fibers creates tiny insulating air pockets that regulate temperature without adding bulk.
Wicking away moisture, especially foot sweat, is essential for all-day comfort, no matter the season. Merino wool helps keep your feet dry and comfortable, whether you're dealing with warm-weather perspiration or the damp chill that comes from stepping into a puddle of melting snow. Other bonuses come with moisture-wicking, too.
Say goodbye to smelly feet, as Merino wool socks are both moisture-wicking and antibacterial. The freshness you retain all day long will help you overcome all your calendar appointments. If you are the outdoorsy type, know that woolen socks can be worn two days in a row if you are planning on an off-grid camping trip.
Merino wool socks that blend the high-quality natural material with other fibers are built to last. While this fabric is strong on its own, it becomes even sturdier when combined with stretchy textiles like elastane, nylon, or polyester.
Never worry about itchiness with antibacterial and hypoallergenic Merino. The material is finer than regular wool, and it is perfect for direct contact with the skin. Say goodbye to the unpleasant itch and rashes. This feature, combined with the absorbent and breathable properties of woolen comfy socks, will also protect you from blistering, injury, and fungal and bacterial infections.
All of Merino’s qualities make it the ideal material all year round. As long as you mind the necessary thickness level, you have your breathable and thermoregulating ally at your literal feet.
Whether you are an experienced hiker on snowy paths or a passionate skier, don your thick, comfy socks and engage in your favorite activities without a hitch. For example, Nordic Socks offers five tiers of thickness, with options 4 and 5 being ideal for outdoor sessions at subzero temperatures.
These special socks have a full terry knitting design. This design cushions your feet against impact and extreme conditions you find in nature during the wintertime. Winter activities can be done with toasty feet, too.
Hiking is the great equalizer: open to all fitness levels, with trails ranging from easy strolls to summit scrambles. But when it comes to gear, the options can get overwhelming fast—especially for something as essential as socks.
To help you skip the trial and error, we’ve put together the ultimate guide to the best hiking socks.
Summer does not have to mean sticking only to sandals and Crocs - while they are comfortable, you can wear comfy socks that will also keep you cool all day long. Choose thin versions of your favorites and let your feet breathe. Remember - it is also best to wear lightweight shoes made from materials like canvas to truly feel at ease even when the sun scorches everything in its path.
When temperatures rise, your choice of socks can make or break your comfort—especially during active days outdoors. If you're wondering what to wear on your feet in the heat, we’ve got you covered.
Check out our in-depth guide to the best socks for summer, where we break down the top materials (like Merino wool and lightweight cotton blends), smart construction details, and key performance features.
Versatility is the strong suit of Merino wool socks. You can wear them in multiple contexts, regardless of the time of year. Don’t believe us? Here is a list of things to do while your feet are clad in woolen socks:
You can do virtually anything, and in complete comfort.
At Nordic Socks, we offer five distinct levels of thickness, ranging from thin and ultra-thin options perfect for everyday wear and warmer climates, to thick and ultra-thick styles designed for maximum warmth and comfort during winter hikes, snow sports, or long days outside.
Explore our full thickness guide here to find the perfect pair for your lifestyle and climate.
There are multiple options for cushioning. Half terry is a knitting style where your toes and heels get an extra cushion. This way, your feet's most sensitive areas get due protection and the rest of the foot feels light, creating the complete comfy socks experience. A half terry design fits best for mild weather and intense physical activity that requires meticulous footwork.
Full terry, on the other hand, gives your entire sock the plush feel. Walk comfortably in your Merino wool socks and feel like you've got a heating pad for your feet!
Longer socks will protect you against elements like tall grass - you have surely had your fair share of them on summer hikes. They also provide additional temperature control, so we recommend getting longer socks when temperatures start dropping.
Contrarily, summertime is the right time for low-cut sock sets. These socks extend to your ankle bone, protecting your foot from your shoe rubbing directly against it. However, they are lighter than their long counterparts, and you can wear them comfortably on hot days or when playing a team sport outside.
Crew socks are the versatile middle ground. They rise a few inches above the ankle, giving you more coverage than low-cuts without the full length of hiking socks. They’re a practical choice for everyday wear, offering both comfort and protection in most conditions.
Durable socks will help you consume more sustainably. Washing, rewashing, and throwing socks away all contribute to a large carbon footprint. On the other hand, brands like Nordic Socks work with farms that follow the Responsible Wool Standard (RWS), making sure Merino sheep are treated ethically and live in healthy, comfortable environments. Besides the fact that the wool is collected ethically, the socks' long duration means that you will not need to burn through the pairs, as you were likely to do with Merino's synthetic counterparts.
Merino wool socks are for everyone. From office workers who need to run errands to athletes who are on a continuous run, comfy socks that pamper your feet will undoubtedly help your performance and quality of life.
Sustained physical effort requires specialised socks. Nordic Socks' Mountain Collection provides you with warmth and support when you brave the rocky and snowy paths of the mountains.
Opt for thinner and shorter versions if you prefer hiking in the summer; and remember, these comfy socks are ideal for camping, too. You can wear them easily, even if you go off the grid and do not have many opportunities to freshen up.
A running habit teaches you how much you need to invest in high-quality socks and footwear. Thankfully, some options will last a long time and help you save on the money and time associated with shopping.
Our Activity Socks collection features sets that help you with your performance. Similar to compression socks, they stimulate the feet's compression points and improve blood flow. Seamless toes will also help you step confidently. So, you not only get comfy socks, but supportive socks at the same time.
You need not be an athlete to require support and comfort. With your feet clad in comfy socks, whether they are from the Activity, Mountain, or Nature collections, you will be free from thermal discomfort, rashes, and painful impact. From working long hours to attending your favorite show, Merino wool socks will unlock the next level of wellbeing.
When it comes to choosing the best grade of Merino wool, blends often strike the perfect balance. Pure Merino is prized for its softness, breathability, and temperature regulation, but when combined with fibers like nylon or elastane, it gains extra durability and stretch. For everyday socks that last longer and perform better, Merino wool blends are the way to go.
