The Darn Tough Hiker Full Cushion is thick and cushiony but not too thick, providing excellent protection for your feet on the trail. It's also incredibly durable and will last years of hiking and backpacking. The tall, boot-compatible cut is perfect for hiking boots, and the soft, comfortable fibers feel great on your feet. But, if you'd rather stick with low-tops, we suggest the Darn Tough Hiker Quarter Cushion. It offers the same qualities but stops short just above the ankle. Darn Tough socks come with a lifetime warranty, which we have used and been impressed with. Can you wear these socks for years and have them replaced? Yup. You have to pay shipping and wait a few weeks. The men's and women's specific fits are true to size and feel great on a wide or narrow foot. The Hiker Full Cushion is the clear choice if you're looking for a top-of-the-line hiking sock, and it's our go-to for long backpacking trips, especially since it can also double as a cozy pair of sleepers.
Unfortunately, extra padding means less breathability, and this design does not incorporate a breathable instep like most lighter hiking socks like the Danish Endurance Unisex Merino 3-Pack or the Darn Tough Coolmax Hiker Micro Crew. We also like Darn Tough's Light Hiker Micro Crew for warmer summertime temps. Some may find that the upfront cost of the Hiker Full Cushion is steep, but given the excellent warranty that allows you to exchange them if they ever wear out, it is a worthwhile purchase. Get the Darn Tough Hiker Full Cushion if you're looking for a boot-capable, durable, cold-weather sock with excellent underfoot cushioning.

The Danish Endurance Unisex Merino 3-Pack is a Merino-synthetic blend sock in a three-pack. It is comfortable, performs well across most metrics, and is compatible with boots or shoes. Breathability is at the top of the class due to a unique venting stitch design that runs across the ankle and up the shin. The cushioning underfoot is sufficient for longer multi-day hikes, trail runs, or day hikes over tough terrain. It also comes in a unisex fit that our male and female testers found snug and true to size.
While this sock has a great price, its performance doesn't match the premium socks we tested. It will hang in there for a few solid hiking seasons but not withstand the many years we have seen with Darn Tough and other brands. It contains less Merino wool than the top performers, and the increased amount of synthetic material doesn't thermoregulate, as do socks with a higher wool percentage. Additionally, the toe box isn't well fitted for those with narrow feet and bunches up, especially when wet (though our testers with wider feet had no complaints). While these concerns are valid, finding a Merino-synthetic blend sock that matches value with performance is hard. However, the Time May Tell Merino Cushion 2-Pack is certainly a good deal as well — but lower in quality. The Danish also comes in multi-color packs to color coordinate with your favorite outdoor threads. The REI Co-op Lightweight Merino Crew sells as a single pair, but it is reasonably priced and is composed of 79 percent merino wool — this exceeds the Danish's composition (38% Merino, 30% wool).
Testing our Danish Endurance's ability to quickly dry at home, as well as its ability to continually wick moisture away from our feet while spending time on the trail in the hot summer sun.
We had to get out of the heat to test these warmest socks. The Smartwool Classic Mountaineer Maximum Cushion is built for cold, wintry weather. It features one of the highest wool contents of anything in our lineup and plenty of thickness to keep your toes toasty when the temps turn frigid. We are highly impressed by its ability to keep feet warm, wicking, and breathability. We tested this sock in boots on a hot (90°s F) workday and were blown away that our feet never felt sweaty. When it was time to kick back and take off our boots, our skin was warm but surprisingly dry.
This sock kept our feet comfortable in various conditions — we even hiked shoeless in the rain! Our feet got wet for sure, but they stayed warm and comfortable. At the end of a long day hiking, the Mountaineer also helped maintain warmth in our sleeping bag and quickly became our favorite warm sleeping sock. This attribute can also be a drawback, however. When we tried to hike in even moderately warm weather, our feet quickly felt overheated and our calves itchy. Because of their thickness, we recommend this sock primarily for cold weather pursuits. Also, there is no elastic around the arch or heel to hold the sock in place so that it may move around. Due to the plushness, this didn't cause any issues with blistering. But cramming all that plushness into a tight hiking shoe can be an issue. While these socks will fit into shoes, we find them much more comfortable in boots. Bottom line, the Mountaineer is a thick sock that will keep you comfy on all your wintry adventures. We also like the similar REI Co-op Merino Wool Expedition, when you want to save a few bucks.
The Smartwool Mountaineer proved even a bit warm for fall evenings. We recommend that you keep this sock in your winter bag, where it will perform splendidly to keep your feet warm in the coldest of conditions.
The Darn Tough Light Hiker Micro Crew offers a thinner, more breathable construction well suited for the warmer months of the year. The high concentration of nylon provides powerful wicking power while the breathable stitching on the instep keeps your foot ventilated. This is the sock to wear if you're prone to sweaty feet or frequently hike in hot climates. The height is compatible with low or mid-calf hiking boots or running shoes, making it suitable for various applications. Its drying speed is impeccable, keeping feet dry on long adventures.
This sock will offer plenty of warmth while in motion (given its high proportion of Merino wool), but it won't offer the same warmth while standing still or sleeping. We would not choose the Light Hiker for winter camping or standing around in the cold. However, if breathable and durable construction is what you seek, then you'll be a happy camper in these socks. Those seeking a bit more warmth in a lightweight sock should take a look at the Farm to Feet Damascus Lightweight Crew. We didn't find it quite as comfortable as the Darn Tough, but it's a worthy alternative in every other way.
The Darn Tough Light Hiker fits snugly and doesn't slip or slide around while hiking. They're tall enough for hiking shoes but won't accommodate tall boots. Keep these socks in your warm weather drawer, as they are not quite warm enough for wintry weather unless you're staying very active.
The Injinji Liner Crew is a new competitor in our lineup, and we were thoroughly impressed with the comfort, breathability, and warmth of this ultra-lightweight liner sock. The design hugs the feet and all the toes, wicking away any moisture from the skin. One drawback of synthetic socks can be the “plastic bag” feel that tends to create toe sweat, but the design of these socks allows for wicking, even between the toes. While these wouldn't be our first choice by themselves for cold weather hiking due to the thinness of the material, they are still surprisingly warm when the weather turns cool. We also enjoyed wearing them around the house as a barrier to the cold floor.
Again, this is not a standalone cold-weather sock. It also lacks any sort of cushioning, so it isn't the best choice for long distances where you're carrying weight. As far as durability goes, you're going to find more money for your miles in other, more robust options. And due to the lack of cushion and less durable materials, this isn't likely to be your one and only hiking companion. However, if you're looking for a cold-weather liner that will keep your feet comfortable, dry, and warm under a thicker sock, this is our first choice for the gear bag. Another excellent light hiker that offers all the same comfort and breathability but runs even a bit cooler is the Darn Tough Light Hiker Micro Crew. It's a smart choice for warm summer days and is a nice option for those who prefer a more classic toe box style.
The Wigwam Hiking Outdoor Pro is one of our longest-tested socks and has proven its longevity and breathability in warm weather. We've tested this sock for over seven years, and it is still strong. After hundreds of miles, some of the fabric is thinning, but remarkably, we haven't torn through. The 100% synthetic construction provides excellent breathability with durable fibers. It'll dry relatively quickly on the trail (compared to other medium-weight socks), making it a good option for both wet and dry environments.
This tried and true hiking sock does have some drawbacks. It isn't the warmest sock in the lineup; once the mercury drops close to freezing, it loses its wicking power. Also, the fit is less snug than other options. This isn't a deal breaker, but it's a consideration when choosing a sock to slip into a pair of boots for a long trek. The design lacks compression paneling, which sometimes causes it to bunch in the toes if the fit isn't just right. All that aside, it comes highly recommended if you're seeking a synthetic design with good durability for warmer-weather adventures (e.g., shoulder season hiking). When winter hits, you may want to consider the warm-wicking breathability of a wool sock, like our favorite cold weather option, the Smartwool Classic Mountaineer Maximum Cushion.
The Wigwam Outdoor Pro is a midweight sock that offers more breathability due to the looser construction. While it doesn't have compression panels around the arch and ankle to keep the sock in place, we found that they were a comfortable warm weather hiking sock.

How We Test Hiking Socks
Our hunt for the best hiking socks began by combing the market to find potential candidates. We then selected the top models to purchase, compare, and wear side-by-side. We considered the most important functions of a hiking sock and designed tests to compare performance. We then wore each sock for at least60 miles while hiking or running on trails. We test throughout the seasons, wearing each sock almost daily throughout the year, updating our findings as we gather new information. We have traveled worldwide, exploring remote locations like the Hornstrandir Nature Preserve in Iceland and the Santa Cruz trail in Peru. We've also put the socks to rigorous use in farm boots during long, hot days. All this ensures we have the most comprehensive review of the best hiking socks for any environment. After field testing, we meticulously compare details and perform a series of objective tests to compare performance. Learn more about our in-depth testing process here.
Our testing process is broken down into five metrics:
Comfort (25% of overall score weighting)
Wicking and Breathability (25% weighting)
Warmth (20% weighting)
Durability (20% weighting)
Drying Speed (10% weighting)

Testing hiking socks took us to a lot of beautiful locations.
How to Choose The Best Hiking Socks
We have compiled four important buying considerations, including size, thickness, and fabric, to help you decide on the best hiking socks for your needs.
What Height Should You Look For?
Hiking socks are offered in various heights, such as quarter, lower calf, mid-calf, and high calf. If you plan on hiking through thick vegetation, a taller sock can provide more protection and typically fits best with hiking boots. A shorter sock will be ideal for hotter temperatures and work well with hiking shoes, but offers minimal coverage and is less compatible with boots.
Is Weight Important?
Deciding on the right sock thickness for your adventures will keep your feet happy while in the elements. Sock thickness ranges from ultralight to heavyweight. Essentially, the thicker the sock, the more warmth and cushioning it will provide, but lighter socks will provide more breathability for high-intensity activities and hot days. When deciding on sock thickness, consider the climates you plan on hiking in and the length of trips, and determine if extra cushioning is needed for longer hikes.
From day hikes to large excursions, finding a sock that works well and keeps your feet happy is important.

What Fabric is Best?
Hiking socks are generally offered in a blend of wool and synthetic materials, including nylon and polyester. Typically, a higher wool-to-synthetic blend will offer a warmer sock and provide natural anti-microbial properties, while a higher synthetic-to-wool blend will provide more breathability and quicker drying. For those looking at hiking socks, fabric type and sock thickness tend to go hand in hand. When looking at the material ratio, consider the climate and intended activity level.
Do You Need Quick-Drying Socks?
If you foresee river crossings or rain in the forecast, it's a good idea to consider drying capabilities. Along with material type, the thickness and weight will also play a large factor in dry time. For those planning multi-day trips, a quick-drying pair of socks can save an otherwise uncomfortable day. Wool retains its insulating qualities when wet, so in the event that your socks do get wet, your feet will stay warm.
No better way to test drying capabilities than in the field.

Analysis and Test Results
This review compares lightweight, medium, and heavy cushion hiking socks with functionality for all adventures. We consider options suitable for different seasons, with varying levels of protection. We evaluate each using five core metrics, comparing each sock against the different metrics to help you find exactly what you're looking for.
What's the Best Value?
Getting a durable sock that won't break down after minimal use is important. Some socks offer better durability and, thus, more mileage for your money. Others are low-priced or sold in bulk to increase their value.
The Wigwam Hiking Outdoor Pro is a synthetic sock that provides good cushioning and breathability for warmer weather pursuits. While it isn't as warm as wool socks of comparable thickness, this can be a benefit in the right conditions. Bottom line is that this is a good general trekking sock if you're on a budget.
We also like the Danish Endurance Unisex Merino. These socks come in a three-pack, making them one of the lowest-priced pairs that we've tested. They are durable enough and have a unique, breathable design that keeps your feet feeling dry. These are great socks if you're looking for some general hiking/work socks that won't break the bank.
The Injinji Liner Crew is also notable here for its low price. While it's very thin and not an overly durable option, it offers a lot of versatility. It can be worn alone in warm weather with shoes or your favorite flip flops (yay toe socks), and it can be used as the name implies: as a liner. If you use it as a liner, it will last a lot longer, and for the excellent price, you could easily grab a few pairs to have for all kinds of use cases.
Darn Tough brand socks are our favorite for value. Even if they're initially more expensive, each pair is backed by a lifetime guarantee that allows you to exchange the socks if you wear a hole — we've used and verified this guarantee, and yes, it's for real. No surprise, this brand offers the best when it comes to durability — Darn Tough socks have consistently outlasted the competition during our decade of testing. When looking at value, don't just consider the initial price, but also how long the sock will last.
A solid hiking sock is integral to any backpacking or hiking adventure on your itinerary. Be sure you buy a pair that works for you and one that has a reputation for great performance.

Socks on Sale
Strategically shopping for socks can pay off. Colors are often updated once or twice per year, and when this happens, the older colorways are usually available at a steep discount.
Comfort
When testing this metric, we considered many variables that contribute to comfort. This includes panels of cushioning, relative thickness, and snugness of fit. We note how each pair feels during low and high-intensity exercise, specifically backpacking, hiking, and running over technical and smooth surfaces. After taking on challenges that push our physical limits, we lay back and observe which is most comfortable for lounging. Socks that fit well with midweight cushioning and a Merino wool composition are typically the most comfortable around the house or fire. Thick wool winter socks are usually most comfortable for sleeping. Those that are a tube of fabric without strategic architecture are less comfortable for adventuring many miles. This review is for both men and women, so we note which socks are unisex and which have designs that are specific to both men and women.
Cushioning Ample Cushioning
While most hiking socks are designed to be comfortable, some contenders stand out better than others. Those with the most underfoot cushioning are typically best suited for technical trails or wearing around home/camp after a long day on the trail. The Smartwool Classic Mountaineer Maximum Cushion is a favorite for this application.
Here's a comparison of the full cushion pairs that we tested. On the top is Smartwool Classic Mountaineer Maximum Cushion. In the middle we have the REI Merino Expedition, which are similar to the Mountaineer but are not quite as thick. On the bottom is our number one sock, the Darn Tough Full Cushion. While it's not as thick as the others, it offers better all around performance.

Lightweight Cushioning
Most of the socks we tested fit into this category, but the “lightweight” cushioning level is seemingly quite variable. For example, the Wrightsock Coolmesh II Crew is super thin with hardly any cushioning. In contrast, our favorite for lightweight cushioning, the Darn Tough Light Hiker Micro Crew, is stacked with more protection. The Danish Endurance Unisex is a relatively thin sock that is less durable than the Darn Tough Light Hiker but is cheaper and has similar cushioning to keep your feet light on the trail.
Here's a comparison of the cushioning and breathable panels on the Farm to Feet Damascus Lightweight (bottom), Danish Endurance Unisex Merino (middle), and the Darn Tough Light Hiker Micro Crew. The Danish Endurance and Darn Tough have more ventilation on the instep (top of foot) so they rate higher in the wicking and breathability category.
Credit: Jon Oleson
For those who love lightweight cushioning, the Darn Tough Light Hiker is our favorite because the fabric performs well in all conditions and feels good. It provides protective cushioning that's responsive enough to carry a heavy pack and protect through the Achilles.
Flipping your socks inside out will you give you some idea of how they'll perform. Here the Darn Tough Light Hiker is shown inside out (left), where you can see the ample padding, breathable panels on top of foot, and compression stitching that keeps everything in place.

The Farm to Feet Damascus Lightweight Crew is another super comfortable contender that claims a 'medium' level of cushioning but is lighter and more similar to the Darn Tough Light Hiker. One drawback is that the cushion panels on the top of the foot caused a blister on the top of one tester's foot on a particularly hot day of hiking in boots. Otherwise, these socks would have been best of class for their comfort, fit, and warmth, whether dry or wet.

Fit
Fit is another function of comfort. A well-fitted sock that doesn't slip or bunch will help you focus on the long miles ahead. The socks that performed the best have integrated compression stitching and thoughtfully structured toe boxes that don't deform under stress. Relative height and compatibility with different hiking shoes and boots also play into this.
Female and male-specific fit are to be considered. Typically, a female-specific sock will have a more narrow profile throughout the toe box and heel. While a sock may be “female-specific” or “male-specific,” it's important to look at your foot. If you have a narrow foot profile and struggle to find a well-fitted sock, consider a female sock option. Consider a male-specific sock if you have a wider foot and women's socks don't fit well.
Most of the socks we tested integrate elastic materials to keep everything in place while on the trail. For example, all the highest performers, such as the Darn Tough Hiker Full Cushion, integrate compression materials around the arch and calf. Darn Tough also uses a more tightly knit design in the fabric that 'hugs' the foot. It's the all-around best option for longer or more technical trails in warmer weather.
The Light Hiker Micro Crew is snug, durable, and breathes well due to the stitch design on the instep.

The Danish Endurance Unisex also has a snug fit with a compression panel around the arch to keep the socks in place. The wide elastic cuffs keep the socks up on long days of hiking. This great all-around hiking sock will keep its shape over the miles.
Another favorite for comfort and performance is the Farm to Feet Damascus Lightweight, a well-fitting sock with superior underfoot protection. It's an excellent option for longer or more technical trails. If lightweight comfort is what you seek, look to this sock or the Danish Endurance Unisex and Darn Tough Light Hiker Micro Crew. Additionally, if your needs or preferences call for an ultralightweight sock that may feel like you're wearing nothing at all, our favorite liner sock is also really comfortable. The Injinji Liner Crew doubles as both a warm-weather standalone sock and as a super comfortable liner under a heavier sock for when the temperature drops.
Danish Endurance socks are designed for three-season comfort, keeping your feet happy in spring, summer, and fall. While they provide warmth, they are better suited for milder temperatures and might not be ideal for the coldest winter days.

Wicking and Breathability
Wicking and breathability are important to avoid the dreaded swamp foot. A sock that can thermoregulate well and move moisture away from your foot will inherently keep you happy and comfortable for long days on the trail. To test this metric, we ran, hiked, biked, and backpacked over distances ranging from one to 28 miles. We also took each sock through a wide range of temperatures and conditions.
Socks with a thinner construction or loosely packed fibers typically breathe better than those that are thicker or have a higher-density construction. The most breathable contenders sport ultralight construction or feature panels and stitching that enhances ventilation. The Darn Tough Light Hiker crushes this category, being a clear choice for a cushioned sock in hot weather. It integrates a thinner wool blend fabric that is good at wicking and instep ventilation and allows water vapor to escape effectively. Yet the sole still provides ample cushion to help your feet stay happy on the trail. This is our favorite if you want a warm or hot-weather sock. If you want the same superior breathability with a lighter cushion, check out the Darn Tough Hiker Quarter Cushion. We recommend this quick-drying model for lower-impact activities in hot weather. A notable mention is the Farm to Feet Damascus Lightweight Crew, which scored highly in this category for superior wicking capability and a thinner instep panel that promotes breathability.

The thinnest and most breathable sock we tested was the Injinji Liner Crew. This contender scored highest in this category due to the superior blend of synthetic fibers and an ultra-lightweight design. It's not the best option if you need more cushion underfoot, though, as this sock has zero padding. But if you need a liner to help wick away moisture and prevent blisters under a thicker sock, this is a clear choice.
Here you can see why the Injinji Liner Crew is so breathable. This sock is thin without any sort of cushion.

The Wigwam Hiking Outdoor Pro is a great option for a medium-weight sock with fantastic breathability. The fit is looser, so it doesn't wick as well as the light hiking socks, but the looser knit and larger coils along the interior of the sock grab moisture to move it effectively away from the foot. Unfortunately, as we observed on a winter camping trip, this sock loses its wicking power in colder weather. Luckily, you can fit a liner underneath the sock to help increase its ability to wick, but our scores reflect its performance when liner-free.

The Danish Endurance Unisex is another with a surprisingly breathable Merino wool-synthetic construction. It features a unique ventilation design on the instep and cuff that helps the foot breathe. The Darn Tough Light Hiker and Farm to Feet Damascus Lightweight both offer a similar level of breathability that is superior. All utilize ventilation patterns along the upper portion of the foot and throughout the length of the calf, while the Darn Tough Light Hiker is shorter in design. Less coverage makes it a more breathable sock suitable for warmer conditions.

The Darn Tough Full Cushion also did well in this category and is incredibly breathable for a heavier sock. It stood up to the hottest days of hiking and work, and there were no hot spots, even in boots. At the end of each day, our feet were surprisingly dry.

If you're seeking a thinner cushioned sock with superior wicking and breathability, the Darn Tough Light Hiker is your best bet. All the socks we tested breathe relatively well, but of the Merino-synthetic blends, the Danish Endurance is our favorite for its thinner materials, followed by the Farm to Feet Damascus.
Hiking and running in wet climates demands a sock that will wick and breathe well. Here we run it out at the start of a 20-mile day on the remote island of Hornstrandir in Iceland. Through this run, we encountered wet, sandy beaches, tall grass, and heavy rain. Through it all, the Farm to Feet Damascus kept our feet relatively happy and warm.

Warmth
A good hiking sock will keep you warm when you need it most, whether summiting a mountain or curling up in a cozy sleeping bag. We considered each sock's wet and dry warmth when looking at warmth. To test warmth when wet, we dunked each sock in water, intrepidly bit down on our lower lip, and hiked around in the cold. To test warmth when dry, we hike in cold and remote places like Alaska during early spring or camp out at altitude through the summer months, where temperatures vary from 10°F to 35°F daily. From splitboarding to snow camping, we ultimately rated each hiking sock based on performance in these conditions.
If sublime warmth is your goal, looking for a sock that integrates more wool than synthetic materials is essential. These socks typically offer impressive warmth when both wet and dry. For example, the Smartwool Classic Mountaineer Maximum Cushion, REI Co-op Merino Wool Expedition, and Alvada Thermal Warm Crew offer the best warmth in both wet and dry conditions, with the proportional amount of Merino wool being higher than other materials.
Here you can see the thick, densely packed 80% wool loops that give the Alvada socks their superior warmth. In all honestly, these socks were too warm to use in all but the coldest conditions. You may want to look into these if you're searching for a sub-zero sock.
Credit: Jon Oleson
Wool insulates when wet and dry more effectively than other synthetic materials like nylon or polyester, giving our highest-scoring socks more warmth and a much wider range of thermoregulation. The Danish Endurance Unisex Merino is an example of a Merino wool synthetic blend that isn't as warm as the socks mentioned above. This is because it integrates only 30% Merino wool among other synthetic materials, whereas the other options mentioned offer between 74% and 80% Merino wool in their construction, along with thicker materials.
We pitted REI's Merino Wool Expedition socks (left) against Smartwool's Classic Mountaineer in a head-to-head test. Both options boast thick cushioning and exceptional warmth for frigid conditions, but the Smartwool emerged victorious in padding and overall heat retention.

Synthetic socks, like the Wigwam Hiking Outdoor Pro, perform well in warmer conditions but lack warmth when temperatures drop as they tend to lose their wicking properties when wet. That said, they still insulate well when wet, offering protection in colder weather as long as you stay mobile.

Toe socks like the Injinji Outdoor Midweight Crew are colder than traditional styles because of their individualized digit design. This keeps toes away from each other, which doesn't enable a 'warming effect,' similar to how mittens are typically warmer than gloves. Of the socks tested, this is the coldest sock in wet and dry conditions.

Durability
Socks do take a beating while exploring outdoors, but a good one should last you for several hundred miles before failing. Testing durability in a short period can be pretty tough, but we managed to see a difference after putting 60 miles on each model. After years of testing these socks, some have changed very little, while others have disappointed.
In our experience, Darn Tough socks are unparalleled in this category. The materials are tightly knit, the fibers are strong, and we haven't had any bad experiences. Even though the upfront cost is relatively high, we know we are buying a product that will last for hundreds of miles. In some of our testing, we've had the same socks for over five years, logged over 600 miles, and they are still wearable. And even when we have experienced a hole, we rest easy knowing that you can send them back and get a replacement pair.

We also love the Farm to Feet Damascus Lightweight, which has gone with us over 500 miles while sailing, fastpacking, and running in Iceland, Colorado, and Canada. After years, they are still at work in our sock rotation. The fabrics are starting to thin out, but we still haven't seen a hole. The Smartwool Performance Light Hike Cushion and Alvada Thermal Warm Crew also performed well in this metric. Even after hiking shoeless and spending long days in farm boots, these socks showed zero wear. Impressive.
The Smartwool Performance Light Hike Cushion didn't score highest in every category, but one thing that it does have is endurance. This showed to be one of the most durable socks, looking totally unphased and like new after all our durability tests. Here we see the Smartwool keeping our tester's feet comfortable while fast packing in the Sierras.

The Wigwam Hiking Outdoor Pro is a burly synthetic model that continues to perform after years as well. After 600 miles, it has compacted a bit but continues to go strong. While the Darn Tough varieties show large amounts of pilling after this time, the Wigwam sock has little to note. After years of testing this sock, we can confidently say it is highly durable.
How should you wash your socks? Turn them inside out, machine wash on a gentle setting in cool or warm water using mild soap, and air dry or tumble dry low.
Drying Speed
A sock that dries quickly has a large advantage on multi-day backpacking trips, especially in rainy climates or on trails that have seen fresh rain. We went hiking and backpacking in the field to test drying speed, purposely dunking our feet into streams and rivers. We continued to hike to see if each would dry out on its own. In addition to these subjective field tests, we performed a precise drying analysis to see how quickly each dry on the line. These two data points help us determine which socks perform the highest in this category.
Most of the socks we tested use wool-synthetic blends, and a few are made fully of synthetic materials. We found that while the type of material determines the drying time (synthetics generally dry more quickly), the weight and thickness of the sock is also a primary factor. The Injinji Liner Crew, Darn Tough Light Hiker, and Wrightsock CoolMesh II Crew demonstrate excellent drying capabilities. The Injinji Liner dried the quickest, in under an hour, with the Darn Tough Light Hiker and Wrightmesh CoolMesh II following second at around 100 minutes. The Injjinji and CoolMesh II sport full synthetic construction, while the Light Hiker is a Merino-synthetic blend. All these contenders dried well on the trail, taking a similar amount of time to dry on foot.
Our side-by-side drying test is key to assessing moisture management in our hiking socks.

The Icebreaker Hike+ Light Crew, Farm to Feet Damascus, and Smartwool Performance Light Hike Cushion came in next place for dry time. All are made of wool-synthetic blends of about the same thickness, similar to the Darn Tough Light Hiker. The Darn Tough Full Cushion was the quickest drying of the heavyweight socks, beating the Smartwool Classic Mountaineer and the REI Expedition by 20 minutes on the dry line (180 versus 200 minutes, respectively). Overall, if you're seeking a fast-drying sock, the Light Hiker, CoolMesh II Crew, and Farm to Feet Damascus offer the fastest drying times.
Hiking provides you with the opportunity to see and connect with the most remote and beautiful places in the world. A good pair of hiking socks will provide you with the means to do that in a comfortable way.
