15 Best Wool Socks 2023

There are socks, and then there are wool socks. The latter are comfier than their cotton or synthetic counterparts — even in summer, which you might not expect. That’s because the very best wool socks are woven from merino wool, a high-performance natural fiber that feels soft on the skin and has odor-fighting properties. Despite stereotypes, merino wool tends not to be itchy, and is still warm and comfortable to wear when it gets sweaty. “Traditional thicker lambswool, when it gets wet, it gets heavy,” explains instructor of textile science Deborah Young. “But merino is so light that it’s able to let go of the moisture, and that provides a cooling effect. It’s also the only natural fiber that is odor absorbent.” This makes wool socks ideal for hiking, biking, and other sports and outdoor activities. Or just getting cozy at home. As Merino Wool Gear’s Jay Spring puts it, merino wool just has a nicer “foot feel — it’s softer, and it cushions more.”

Wool socks also tend to be much more expensive than other kinds, and not all of them are created equal. To find out which are worthy of your top drawer, I tried out a number of best-selling brands and consulted with textile experts, outdoor enthusiasts, and stylish people about what wool socks they stand by. And, well, walk around in.

If you’re paying more than $20 for a single pair of socks, they should stay hole-free. Many brands — but not all — actually offer a lifetime guarantee on their wool socks, which can make them well worth that initial investment. Most of the recommendations here have a guarantee of at least one year, with the brand offering to replace any pairs that don’t stand the test of time. Just a note on sock longevity, per Spring: Even if a brand says it’s okay, you probably shouldn’t put your wool socks in the dryer. “I would never,” he says. “The best way to do it is to flat dry them on a towel — don’t hang them up, because they’ll lose their shape.” He also suggests avoiding hand washing, “unless you really know what you’re doing, because the detergent can get stuck in the fibers.”

I primarily looked for socks woven with at least 40 percent merino wool, which has fine, non-itchy fibers with natural odor resistance. Crucially, these fibers can absorb a lot of water before the wearer experiences any discomfort or cold. “Merino will keep you warm even when it’s wet, which is really good when it comes to sweating,” Spring explains. “The sock itself takes in the moisture.” No, really: “Merino can absorb 30 percent of its weight and still feel dry, whereas a synthetic can absorb 7 percent of its weight and still feel wet,” Young adds. The best merino wool socks, our experts noted, are still blended with other performance textiles like polyester, silk, spandex, and nylon, which makes them more durable and flexible, particularly for sports and hiking. Avoid wool socks blended with cotton, which doesn’t share the moisture-wicking properties of wool, and won’t regulate heat.

When it comes to weight and scratchiness, Spring says to go by this rule: The finer the weave, the softer the sock. Merino is already a very fine wool compared to other kinds, but sock manufacturers will adjust the weave across different designs. “The thinner wool socks are super soft, but not as durable, and harder to wash,” he explains. “Those are more luxurious. The heavier wool is for outdoor use, and is often mixed with synthetics, because merino by itself isn’t the strongest material.”

On that note, when it comes to buying wool socks, Spring says that “it’s about knowing what you need before getting it.” Wool socks are highly engineered for specific purposes: hiking, lounging, or even wearing to the office. I broke down these picks according to intended use, whether that’s a technical activity like skiing or just putting on boots to go to the store during winter. For example, technical wool socks are often woven with extra cushioning and support around the toes, heel, and sole, for durability and to prevent blisters. These would suit hikers but might be too heavyweight for everyday or formalwear.

Durability: Lifetime guarantee | Materials: Merino wool and nylon | Comfort: Extra cushioning | Intended use: Hiking and outdoor

We here at the Strategist are big Darn Tough fans. I’ve worn my favorite pair of the Vermont brand’s famously comfortable and durable merino wool socks while clambering up volcanoes in Guatemala and working from home in a building with capricious heating. Darn Tough socks have a thick, bootie-like weave that makes them a pleasure to wear. They also come with a lifetime guarantee, meaning the brand will replace your socks if you get any holes. Former Strategist writer Jordan Bowman says his pair stands up to snow shoveling and hiking expeditions. “They’re padded to add comfort, so you will immediately notice the thickness in comparison to medium-weight socks like Uniqlo’s and Muji’s,” he explains.

Darn Tough is Spring’s wool sock brand of choice, too. He’s been rotating between the same six pairs for years. “They’re the kings of the industry for sure,” he explains. “I can’t say a bad thing about them.” He thinks you can’t beat Darn Tough’s lifetime guarantee, and adds that it’s a small-scale, independent operation with a higher degree of oversight than you might get with multinational outdoor brands: “Once you get that big business scale with merino, it’s hard to maintain quality.”

You’ll also hear Darn Tough praised by many hikers and backpackers — especially those who venture out in all four seasons. REI’s virtual outfitting team lead, Forrest Jarvi, tells us that it’s worth paying extra for the brand’s merino wool socks when embarking on multi-day backpacking trips, specifically because they’re anti-odor. “Which is handy, especially if you’re sharing a tent.”

These hardy wool socks are even beloved by Transportation Secretary Pete Buttigieg, who wore them while serving in Afghanistan and still puts them on for long-haul flights.

Durability: No guarantee | Materials: Merino wool, nylon, polyester and spandex | Comfort: Reinforced toe and heel | Intended use: Hiking and outdoor

Considerably cheaper are these American-made merino wool socks discovered by former Strategist associate editor of audience development Mia Leimkuhler; she and her husband wear them all winter in Montreal, where they live. Leimkuhler marvels at the fact that they are so cheap while also being made of over 70 percent merino wool — but warns that they’re bulky. “They are really, really good, but they are thick, perfect for winter boots, hockey skates, or wearing around the house,” she says.

Durability: No guarantee | Materials: Merino wool, nylon, polyester and spandex | Comfort: Cushioned footbed, stay-up ankle | Intended use: Hiking, everyday

These wool-and-polyester socks from Strat-beloved brand Bombas are perfect for travel and everyday purposes, being stretchier and thinner than Darn Toughs, as well as much more neutral looking. Unlike some of the sportier styles listed here, these socks come in outfit-matching shades of charcoal, olive, and a popular off-white (that’s currently sold out). They’re available in three different sizes for optimum fit. Fashion-brand marketer Jenny Olson told us that she wore them while road-tripping through South America in a ’70s Series Land Cruiser, adding that they are “super-soft” and also kept her feet warm and cozy while hiking.

Durability: No guarantee | Materials: Merino wool and silk | Comfort: High length | Intended use: Everyday

Dan Snyder, a menswear designer and founder of Corridor, is a fan of these wool-silk-blend socks from American Trench. He says they’re ideal for cold weather because they’re warm and come up “superhigh,” which makes them perfect for wearing with winter boots. Like the Darn Tough socks above, these are knitted in a small, family-owned North Carolina mill. Though pleasingly autumnal in hue, they’re a little less crunchy in their aesthetic than the hiker-specific socks on this list — note those little flecks of color designed to peek out between your shoes and pants. Personal-branding and lifestyle consultant Victoria Hitchcock agrees that American Trench makes a “gorgeous sock” that’s both “old school and hip.” Trying a pair for myself, I agree that these are uncommonly old-fashioned socks, but in a good way. They’re thick and just a little slouchy, and look beautiful above a Blundstone.

Durability: No guarantee | Materials: Merino wool, nylon, and polyester | Comfort: Tabi toe | Intended use: Everyday

If you’re wearing tabi boots or sneakers this winter, Peng recommends investing in these merino socks that feel like “a nice sweater for your feet.” In fact, the brand says they’re actually woven from the same high-grade wool used for luxury sweaters. They hold their tabi shape too, due to having “extra threads between the toes that make them stronger and more durable.” The foot feel is smooth and luxurious, with a close and comfortable fit that makes them appropriate for a variety of toed and non-toed footwear, including loafers.

Durability: No guarantee | Materials: Merino wool and nylon | Comfort: Reinforced heel and toe | Intended use: Office

Spring put us onto the very-specific wool sock brand Boardroom, which makes socks for — you guessed it — office settings. The brand’s classic-looking ribbed socks, made in the USA from merino wool, nylon, and spandex, are woven with reinforced heel and toe sections that will add comfort to the commute. So that you don’t get any awkward scrunching between your shoes and trouser cuffs, they sit nice and high over the calf all day. We also like that the brand sells a mesh sock laundry bag that will protect up to six pairs of wool socks as their precious fibers churn around in the machine.

Durability: 2-year guarantee | Materials: Merino wool and nylon | Comfort: Seamless toe, padding | Intended use: Running and sports

As someone who runs outside in all seasons (including some questionable weather conditions), former Strategist senior writer Karen Iorio Adelson has tried a lot of sock brands. Smartwool’s crew socks top her list for winter running: She likes that they “cover more of my ankles, compared to low-cut or no-shows, so the gap between my tights and my socks stays covered and warm.” The socks are woven with runners specifically in mind, incorporating a “seamless” toe to avoid friction with your running shoes. The women’s socks also have a narrower fit than the men’s. Smartwool was a brand mentioned by a few of our experts, including Spring — like Darn Tough, they’re synonymous with technical sock manufacturing. Though they don’t quite offer a lifetime guarantee on their products, they do promise at least two years of wear or a free replacement. Which for everyday runners is still a pretty good deal.

Durability: 2-year guarantee | Materials: Merino wool and nylon | Comfort: Seamless toe, padding | Intended use: Running and sports

For warmer months, Smartwool also makes these no-show socks with a similar merino-wool composition to the crew-length pairs above, and the same “seamless” toe for added comfort as you pound the pavement. These ones also have a two-year guarantee.

Durability: Customer service form | Materials: Merino wool and nylon | Comfort: Flex zones | Intended use: Cycling and sports

Compared to regular athletic socks, pairs designed for cycling are generally thinner, so that riders can get better feedback from their shoes and pedals. But that doesn’t mean they have to be cold. Recreational cyclist and travel writer Sebastian Modak tells us he wears these merino wool socks “religiously” in the winter to stay warm on his bike. “When I’m wearing them, I never even notice if my feet are overheating or too cold,” he says. We especially like that this pair is designed with “flex zones” at the ankle, to prevent bunching while you’re on the bike and are unable to reach down and make adjustments. While the brand doesn’t exactly guarantee it will replace these socks if they fall apart prematurely, it does promise to “take care” of any unsatisfied customers via this complaint form.

Durability: Lifetime guarantee | Materials: Merino wool and nylon | Comfort: Ventilation, padding | Intended use: Hiking and outdoor

Merino may be more moisture-wicking and odor-neutralizing than other fibers, but some of us still sweat enough to be wary. Enter Farm to Feet, another big player in the wool sock game that Spring says is known for its innovations around padding and ventilation. He also points out the brand’s entirely U.S.-based supply chain: Its socks are all-American, from sourcing to manufacturing. This pair of technical merino socks, which would especially suit long-haul hikers with fussy feet, has a higher ratio of nylon to merino fibers than others on this list. This makes them both more durable and flexible. Ventilation strips sit on top of the foot, and the socks also have blister-protecting padding on the soles. Farm to Feet offers a lifetime guarantee on its products — and should you return a pair you’re unhappy with, promises to recycle them.

Durability: Lifetime guarantee | Materials: Merino wool and polyamide | Comfort: Reinforced toe, seamless | Intended use: Everyday

New Zealand brand Icebreaker makes some of our favorite merino products. When it comes to wool, it makes sense to trust a country known for its millions of sheep, no? While I’m loyal to my Darn Tough socks for hiking, I think these slimmer socks are great for more everyday wear. While still reinforced at the heel and toe, they are thinner and have fewer seams — this results in a looser and less rigid construction that more resembles your traditional cotton sock. Despite ostensibly being lighter and less durable than others on this list, all Icebreaker socks come with a lifetime guarantee and are replaceable — no questions asked — should you wear them out.

Durability: 5-year guarantee | Materials: Merino wool, nylon, polyester, and lycra | Comfort: Extra stretch, padding | Intended use: Cycling and other sports

For a technical wool sock that will suit a variety of physical activities, look no further than Strategist writer Jeremy Rellosa’s favorite pair from North Carolina “microsockery” DeFeet. They’re designed for cycling, but he also wears them when running and hiking. The secret to their versatility? A higher percentage of nylon and polyester in the weave, plus some Lycra for extra stretch. “And they have just the right amount of cushion without being too plush,” Rellosa adds. As for the profile, “they’re stretchy but keep their shape and don’t get frumpy like other chunky wool socks that I have.” He’s also convinced that the generous cushioning helped him break in a pair of stiff leather Paraboot shoes this past spring.

Durability: Lifetime guarantee | Materials: Merino wool and nylon | Comfort: Extra cushioning | Intended use: Ski and snowboarding

Snow sports is yet another category that Darn Tough socks dominate. Daryl Morrison, a former alpine racer and ski expert for the gear recommendation and shopping site Curated, says they’re the only socks she buys because they’re so warm and durable, adding that she still has pairs from high school. These socks sit nice and high on the calf, to accommodate ski boots, snowboard boots, or whatever shoes you’re wearing while traversing between the slopes and your car. The brand promises “no slipping, no bunching, and no blisters,” with a weave so fine that you should forget you’re even wearing socks in the first place.

Durability: One-year guarantee | Materials: Merino wool and nylon | Comfort: Water resistance | Intended use: Hiking and outdoor

For running, hiking, or just walking the dog on a rainy day, you can opt for a waterproof wool sock, like this one recommended by Strategist contributor Steven John. He says his feet “stayed totally dry” after running on a particularly wet day (with non-water-resistant shoes), thanks to the socks’ three-layer construction. There’s an inner wool layer to pull moisture away from your skin, and a waterproof mid-layer and nylon outer layer to prevent water from getting inside. Showers Pass socks are guaranteed for 12 months after purchase, with worn-out socks repaired or replaced. If you’re after a lighter waterproof sock, the brand also sells a non-wool version of these.

Durability: No guarantee | Materials: Alpaca wool, bamboo, nylon, and spandex | Comfort: Side ventilation mesh| Intended use: Sports and outdoor

The experts I spoke with were evangelical about merino-wool socks, and for good reason: Merino is a high-performance fiber that’s increasingly well priced and widely available for purchase across many major fashion and outdoor brands. Alpaca wool is much less ubiquitous, but it’s actually even better at retaining heat, reducing odor, and wicking moisture while you sweat. I’ve been wearing these socks from Peruvian brand Paka for the past year and am crowning them the softest that I’ve ever owned. They’re fuzzy but never itchy, they retain their shape, and they are breathable enough to run or hike in. They’re also super lightweight, which is ideal for backpacking.
