You can’t overvalue a great pair of hiking socks: They keep your feet comfortable and dry while helping to prevent blisters and hotspots. We've tested the full array of styles in varied conditions from the heat of Utah’s Canyonlands to the snow of Washington’s North Cascades, and below are our picks for the best hiking socks of 2022. Most of our favorites are made with merino wool, which has become the standard-bearer in socks and performance outdoor apparel in general. It’s true that quality hiking socks are pricey—they generally run in the ballpark of $20 per pair—but all of the options below are tough enough for trail duty and made to last. For more information, see our hiking sock comparison table and buying advice. And for more on hiking footwear, we’ve tested and written about hiking boots and lightweight hiking shoes.

Best Merino Wool Hiking Sock
Materials: 61% merino wool, 36% nylon, 3% spandex
What we like: Comfortable and last forever.
What we don’t: Tough construction means they aren’t quite as plush as some other socks on this list.
Smartwool used to be synonymous with hiking socks, but over the past few years Darn Tough has taken the lead. With cozy seamless construction, high-quality merino wool, and a lifetime warranty to back it up, Darn Tough socks simply are the best. Our favorite model for hiking and backpacking is the Micro Crew Cushion. High-density knitting creates excellent padding and breathability for virtually any 3-season outdoor activity. The fit is super comfortable, not overly elasticized around the arch or forefoot, and doesn’t bunch or create pressure points.
As we've found, no sock is totally perfect. Our nitpicks with the Micro Crew are that the cushioning underfoot can make the sock a little warmer on hot days than thinner models like the Smartwool Performance Hike Light below, and the tough construction means losing a tiny bit of plushness. But this is telling: In all the miles we've racked up with our Micro Crews (some are 7+ years old and counting), we haven’t put a hole in one sock. And if you like Darn Tough socks but are looking for something a little more breathable, check out their Light Hiker Micro Crew Lightweight model ($22), which is a thinner alternative with a performance fit similar to the Smartwool Performance Hike Light below.

Best Lightweight Sock for Summer Hiking
Materials: 46% merino wool, 51% nylon, 3% elastane
What we like: Light and breathable design is great for summer hiking.
What we don’t: Minimal cushioning impacts comfort as the miles add up.
For warm-weather hiking, trail running, and casual use with your sneakers, a minimally padded sock makes a lot of sense. And among the various ultralight options, Smartwool’s latest Run Zero Cushion Ankle Socks are our favorite. Competitively priced at $19, you get a great, snug fit, superb breathability, and a very comfortable feel. And as with the Performance Hike Light Cushion Crew below, Smartwool added Indestructawool to these socks for a boost in durability. They still won’t last forever, but the Run Zero Cushion is a nice option for summer when you don’t need serious padding and thickness.
What are the downsides of choosing an ultralight hiking sock like the Smartwool? The materials are considerably thinner than the Darn Tough above, even in critical areas like the heel and toe box (although there is some reinforcement at the toes). But if you have tough feet and can avoid blisters, these socks will help keep your feet cool even during the hot summer months. And if you need some extra impact resistance, Smartwool does offer “targeted cushion” options within the same Run lineup, which add more padding around the heel and ball of the foot.

Best Budget/Synthetic Hiking Sock
Materials: 77% Coolmax EcoMade, 22% nylon, 1% spandex
What we like: Around $5-$10 cheaper than the merino competition.
What we don’t: Holds onto stink more than wool.
Not everyone is willing to spend $20+ on a pair of hiking socks, which we understand, and REI Co-op offers a budget-friendlier alternative to merino wool with their Coolmax EcoMade Lightweight Hiking Quarter. Made with fabric constructed from recycled plastic bottles, these socks provide a soft next-to-skin experience without the usual environmental burden of polyester (REI has been strong of late on the sustainability front). They wick moisture well too, making them a great choice for hot-weather adventures when you still want decent cushioning and support.
What do you sacrifice by saving with the REI Coolmax EcoMade? For starters, the synthetic material holds onto stink more than merino. And compared to Darn Tough’s Coolmax sock below, the REI generally fits a bit less snugly, especially over time (although they are the better value). In the end, if you’re anticipating a long-term investment for hiking and backpacking, it’s probably worth going the merino route. But the REI Coolmax excel for casual outings and light outdoor use, which is all many hikers need. Finally, this series also includes thinner, ultralight quarter socks ($12), as well as higher-riding crew options ($14-$16).
See the REI Coolmax EcoMade Lightweight
Best No-Show Hiking Sock
Materials: 32% Drynamix, 11% nylon, 3% neofil, 2% elastane
What we like: The most low-profile socks on our list and very comfortable.
What we don’t: Minimal coverage and no wool.
The crew and quarter-height socks above cover the heel and ankle, but no-show designs like the Balega Hidden Comfort ride even lower. Paired with a low-profile hiking shoe or trail runner (there isn’t enough clearance for ankle-height boots), the minimalist design offers sufficient cushion between your foot and shoe while minimizing bulk. Additionally, while many medium-cushioned socks run too warm during hot summer months, the Hidden Comfort’s synthetic Drynamix build wicks moisture and ventilates well (it also offers enough impact resistance for high-mileage days or while backpacking). All in all, these socks are highly comfortable, breathable, and stylish to boot.
As we touched on above, merino resists odor better than polyester, and no-show socks like the Hidden Comfort are more prone to letting dirt and grime sneak in through the top. Further, it’s important to ensure that the collar of your shoe falls below the top of the sock, as any gaps can cause uncomfortable rubbing. But for those who don’t mind the obvious sacrifices in protection and coverage, the Hidden Comfort is undeniably well made, good-looking, and super soft, which is a great combination for hiking (and did we mention no sock tans?). Finally, it’s worth noting that we had the brand’s Blister Resist ranked here previously, which adds in mohair to limit friction, although we haven’t experienced hot spots in either design even after all-day outings.
See the Balega Hidden Comfort
A Thru-Hiking Favorite
Materials: 61% merino wool, 37% nylon, 2% spandex
What we like: Cool, light, and very durable—a great match for long distances.
What we don’t: The lower cut means less protection.
Casual hikers may not care much about the construction of their socks, but thru-hikers covering long distances on trails like the AT or PCT prioritize an effective combination of breathability and durability. Enter Darn Tough’s Quarter Cushion, which is consistently one of the most popular and top-rated designs on the PCT. With these hiking socks, you get all of the comfort, moisture-wicking ability, and odor protection of crew-height socks, but in a trimmed-down form. It's true, they aren't tall enough for all hiking boots, but they're a great pairing with ankle-height hiking shoes or trail runners (and importantly, they offer considerably more coverage and protection than no-show designs like the Balega above).
Keep in mind that the Darn Tough Quarter Cushion aren’t true ultralight socks like the quarter-height Smartwool Run Zero Cushion above, meaning that your feet can get warm in the heat of summer and won’t dry out as quickly. But we appreciate the less bulky feel and added durability and heartily recommend these socks to anyone who doesn’t care for the higher cut but still wants the cushioning and coverage over the heel and ankle. There's a reason these socks are popular with high-mileage thru-hikers and serious backpackers: They get the job done.
See the Men's Darn Tough Quarter Cushion See the Women's Darn Tough Quarter Cushion
Best for Added Warmth in Mountain Conditions
Materials: 66% merino wool, 32% nylon, 2% Lyrcra
What we like: Darn Tough quality and toughness in a winter-ready build.
What we don’t: Pricier than the Smartwool Classic Hike Extra Cushion below.
Darn Tough’s Micro Crew Cushion socks above are a great option for moderate temperatures and even into the shoulder seasons, but for true mountain-ready performance, we like their beefier Hiker Boot Full-Cushion. Stacked up against the Micro Crew above, the model here boasts thicker cushioning with more merino (66% vs. 61% for the Micro Crew), giving it a nice boost in coziness and insulation for activities like summer-time mountaineering and winter hiking and snowshoeing. We also love the performance fit, which provides a secure, snug feel that stays in place and doesn’t feel overly bulky. All told, these socks are well built, impressively durable, and highly comfortable for long days in frigid temps.
As with all heavyweight socks, you’ll want to take your boots into consideration before buying to ensure you have enough room. That said, the Hiker Boot Full-Cushion does have a noticeably lower-profile and less cumbersome feel than Smartwool’s Classic Hike Extra Cushion below (one editor accurately described the Smartwool as slipper-like).The Smartwool does get the edge in price ($23), but it contains less merino (56%), and we prefer the tighter and more streamlined fit of the Darn Toughs for maximizing performance while minimizing bulk (on the flip side, we like wearing the cushier Smartwool on hut trips and more casual winter adventures). Both socks run too warm for most sub-alpine summer outings, but if your itinerary includes logging considerable mileage above treeline, the Hiker Boot Full-Cushion is a proven option that should last many seasons.

Best of the Rest
Materials: 56% merino wool, 42% nylon, 2% elastane
What we like: Performance fit and now made with recycled materials.
What we don’t: Can't match Darn Tough's lifetime guarantee.
Smartwool recently overhauled their popular PhD collection with a number of notable tweaks to the design. Key changes include the use of sustainable materials (the Hike Light here uses 31% recycled nylon), increased cushioning (especially under the arch), and Smartwool also updated the mesh zones and overall fit. But most of the winning recipe remains largely the same, including sufficient padding under the heel and forefoot for trail running, hiking, and lightweight backpacking, as well as good breathability and a secure, foot-hugging shape. And we love the modernized designs and patterns, including mountainscapes and brighter colorways.
We’ve had durability issues with previous Smartwool models—particularly at the heel—but the brand now uses Indestructawool technology, which is a denser and tougher wool blend. The Performance Hike Light has Indestructawool in the heel and toe, and we must say it has proven to be durable over the past few years without a noticeable change in comfort. Smartwool still can’t match Darn Tough's lifetime guarantee (although two years is pretty good), but we think the updates to the new Performance collection are positive and give them a leg up in some areas, including fit and plushness.
See the Men's Performance Hike Light See the Women's Performance Hike Light
Materials: 63% merino wool, 35% nylon, 2% spandex
What we like: Excellent fit, breathability, and cushioning for performance use.
What we don’t: Lacking in plushness and everyday appeal.
Technically billed as trail running socks, Swiftwick’s Pursuit Four is an excellent all-around performance pick. The socks were quick to win us over on ambitious outings and high-mileage days: The fit is snug and almost compression-like in feel (similar to their Flite XT model below), breathability is excellent even in warm summer temperatures, and you get a just-right amount of cushioning for high-impact activities like mountain biking, trail running, or hiking in trail runners (which generally have less protection underfoot than typical hiking shoes). Finally, we really like the height, which lands between a quarter-length design and traditional crew-cut models (we’d categorize it as close to a 3/4-length crew).
Importantly, Swiftwick lists the Pursuit Four as having medium cushioning, but we’ve found that it’s noticeably thinner and more breathable than options like the Darn Tough Micro Crew Cushion and Balega Hidden Comfort above. Given its technical slant, the Pursuit Four does lack some of the casual appeal and downright plushness of options like the Balega and REI picks above and below. But for more technical pursuits that require your feet to work hard, you’d be hard-pressed to find a more well-rounded option, and it doesn’t hurt that the Pursuit Four is priced nicely at $20 (true compression models typically cost much more). For a more hiking-focused alternative from Swiftwick with a slightly taller cut and more padding, see their Pursuit Hike Six Medium.
See the Swiftwick Pursuit Four
Materials: Inner layer: 70% polyester, 26% nylon, 4% Lycra; Outer layer: 71% polyester, 24% nylon, 5% Lycra
What we like: Great protection from blisters.
What we don’t: Not very cushioned.
Wrightsock has come up with an interesting solution for those with tender feet that are prone to blistering. Made with a unique double-layer construction, the Coolmesh works to absorb friction from your shoe or boot to limit potential trouble spots. Additionally, the moisture-wicking inner layer keeps your feet dry, providing yet another barrier against blisters (one editor described the feeling as similar to wearing a snug, skin-tight baselayer underneath a cozy midlayer). In fact, Wrightsock believes in their designs so much that they offer a “blister-free guarantee.” A refund won’t matter much if you’ve been suffering on the trail, but we do appreciate the confidence.
All that said, there are some inherent drawbacks to the Wrightsock’s two-layer construction. Most notably, we’ve found that the inner layer occasionally catches on our toes, which makes these socks a little more complicated and tedious to put on than traditional models. Another concern is long-term durability, which is largely a result of the fairly minimal padding. But if you want a light hiker for the summer months that will keep your feet cool and ward off hot spots and blisters, the Wrightsock has a lot of appeal. And if you like the design but prefer more coverage, Wrightsock makes the Coolmesh in a crew-height version for $17 (both models strike us as a decent value).

Materials: 51% merino wool, 46% nylon, 3% Lycra
What we like: High-quality design that is sourced and made in the U.S.
What we don’t: Less merino and pricier than the Smartwool Performance Hike Light above.
Designed with thru-hikers in mind, Farm to Feet’s Damascus Lightweight Technical Crew offers a nice blend of breathability and cushioning for long days on the trail. With a seamless toe area for minimizing bulk and preventing blisters, strategic padding in high-wear areas, and a snug performance fit, the Damascus is purpose-built to handle trail life. Further, all Farm to Feet socks are backed by the company’s generous lifetime guarantee that rivals Darn Tough’s well-known warranty. But what sets Farm to Feet apart is that their products are 100% sourced and made in the United States, including American-raised sheep providing the merino wool.
The Damascus’ closest competitor on this list is the Smartwool Performance Hike Light Cushion Crew above, which boasts slightly more merino (56%) at $1 less per pair. However, the Farm to Feet is no slouch. Specifically, we like the sock’s thick panels of padding over the forefoot, which reduce friction between your foot and boot to keep you comfortable on longer objectives. Another draw is Farm to Feet’s superior warranty (Smartwool’s is only two years), which could be a deciding factor for those who put in a lot of miles. The Damascus lineup also includes no-show, quarter-height, and medium-cushioned crew socks that share similar overall designs and features.
See the Farm to Feet Damascus Lightweight
Materials: 39% nylon, 23% merino wool, 23% Olefin, 12% polyester, 3% spandex
What we like: Great performance fit and very durable.
What we don’t: Not a standout in plushness, breathability, or odor-fighting ability.
There are a dizzying number of hiking socks on the market, but Swiftwick’s new Flite XT Trail collection stands out as one of the most feature-packed and purpose-built options on our list. Made in quarter- and crew-height versions (we’ve included the former here), the socks are made with a functional mix of long-lasting and durable materials, have a snug fit around the heel and ankle with supportive elastic to lock your foot in place, and boast grippy panels at the front and back to keep you from sliding around in your shoes. A final highlight is the use of moisture-wicking Olefin fabric, which accounts for 23% of the construction and has proven to be particularly functional for high-output activities like trail running and mountain biking.
We think the Flite XT Trail line is a solid all-around effort, especially for athletes that prioritize a close fit and long-term durability. That said, the socks contain relatively little merino, which we’ve found translates to a drop in plushness and comfort compared to many of the picks here. It also detracts from the socks’ ability to fight odors—they get smelly faster than alternatives like the Darn Tough Micro Crew and Smartwool Performance Hike Light above. Finally, the Flite XT Trail is on the less breathable end and has led to sweaty feet in temperatures above around 60 degrees while hiking and running (they’re best suited for active use in cooler weather). But if the performance characteristics appeal to you, the Flite XT Trail is an undeniably quality option and one of the most intentionally built designs here.
See the Swiftwick Flite XT Trail Two
Materials: 72% merino wool, 26% nylon, 2% spandex
What we like: Great value, soft feel, and certified to the Responsible Wool Standard.
What we don’t: Design is a bit dated and prone to pilling.
If you’re sold on the benefits of merino but are looking to save, the REI Merino Wool Ultralight Crew hiking socks are just the ticket. For a reasonable $16, you get the comfort and temperature regulation one expects from merino (and a lot of it at 72%) with few compromises. These socks are soft, wick moisture well, and offer sufficient padding for most moderate hiking and backpacking with added reinforcements in friction-prone areas like the heel, toe, and footbed. And REI recently tacked on an RWS (Responsible Wool Standard) certification, which ensures that sheep were treated humanely during production.
Before buying, it’s important to note that REI’s “ultralight” designation is a bit of a misnomer—these socks are noticeably thicker than a true ultralight option like the Smartwool Run Zero Cushion above and fall more in line with the lightweight models on our list. Further, the design in general is a bit of a throwback with drab colorways and a looser (rather than performance-focused) fit. Finally, we’ve noticed that the socks are prone to pilling on the upper portion, and they lack the crossover appeal of many of the more modern options above. But again, you’d be hard-pressed to find more merino for less, making REI’s Merino Wool collection an excellent value for most casual outdoor-goers. For a slightly thicker alternative with more modern and fun styling, check out REI’s New Route Crew Socks.

Materials: 39% Coolmax, 58% nylon, 3% Lycra
What we like: Five-toe design can help with hotspots.
What we don’t: Takes longer to put on than other socks and can spread out the toes.
Right off the bat, we’ll note that Injinji socks are a far cry from the more traditional designs above, and the polarizing looks will be enough to deter many hikers. And we’ll admit that we were skeptical too before trying them out, but we’ve come to appreciate some of the performance benefits. Essentially, instead of a standard sock, Injinji uses a five-toe design that claims to reduce the possibility of blisters and hotspots. And in use, we’ve suffered no discomfort, and the separation has left our toes dry even after long and sunny days on the trail (although the “Midweight” sock here runs warmer than their “Original Weight” models).
All that said, there are some downsides to be aware of with the Injinji’s unique design. First and foremost is the added effort that it takes to put on these socks, as each toe needs to be worked into the appropriate slot. And it’s taken some time to get used to the feeling of having each toe separated in our hiking shoes, although the slight awkwardness did fade after a short time. In the end, here’s our take: If blisters and hotspots are a major issue for you, it may be worth giving the Injinji a shot. If not, traditional hiking socks perform great and require less work.
See the Injinji Trail Midweight Mini-Crew
Materials: 56% merino wool, 42% nylon, 2% elastane
What we like: Durable, cozy, and cheaper than the Darn Tough Hiker Full-Boot Cushion above.
What we don’t: Less merino than the Darn Tough and runs very hot in summer temperatures.
Chances are that if you like Smartwool’s lightweight hiking designs, the Classic Hike Extra Cushion Crew will make you happy as well. Slotting in just below their max-cushioned Mountaineer Classic, these burly socks are one of only two heavyweight models on our list (joining the Darn Tough Hiker Boot Full-Cushion above). In terms of construction, they’re made from 56% merino wool (10% less than the Darn Tough) and have the same traditional look and feel as the brand’s popular Classic Hike Light Crew but with a noticeable boost in warmth and cushion. The obvious compromise is a drop in breathability, but the extra padding and insulation are great for winter outdoor activities and those who prefer maximum support and impact resistance (again, be sure to take your boot size into account, as these socks add considerable bulk).
As we alluded to above, most people will find socks like the Darn Tough Hiker Full-Boot Cushion and Smartwool Classic Hike Extra Cushion way too hot for most summer outings. This lack of year-round appeal—combined with the Smartwool’s thicker and bulkier fit and feel—is enough to bump these socks toward the bottom of our list, but they nevertheless are a nice option for shuttling heavy loads in cold temperatures and will save you $4 over the Darn Tough. And for an even cheaper option that’s similar to the Smartwool, check out the popular REI Co-op Merino Wool Expedition ($21). Comparing the two, the Smartwool is thicker, more durable, and has a better overall fit (the REI is a little too loose for our tastes). As such, we think the Smartwool is worth the extra money in most cases. But for easy-going activities, the REI is a fine choice.

Materials: 37% nylon, 34% Coolmax, 26% acrylic, 2% Lycra, 1% other
What we like: A high-performance synthetic sock.
What we don’t: We still prefer merino over Coolmax.
On particularly hot summer days, you just might not want to put wool on your feet, which is understandable. For these occasions, Darn Tough makes a synthetic sock with Coolmax polyester (the same material used in the budget REI option above), a highly porous fabric that is made specifically to keep your feet cool. These socks are a nice option for hot-weather hikers, and like our favorite merino models, they are snug-fitting, well cushioned, and do not stretch with use. All that, and the bump in breathability is noticeable.
Compared to REI’s Coolmax sock above, Darn Tough’s version is better-made and offers a much closer fit (the downside is a jump in price). In fact, it’s one of the only non-merino socks that you’ll find us recommending for serious performance use. Unfortunately, Coolmax socks undeniably hold stink far more than merino models, which is a big downside for multi-day backpacking trips. Unless you’re specifically looking for an alternative from wool or hiking in the warmest of temperatures, we still deem merino to be superior in almost every way.

Materials: 32% merino wool, 32% stretch nylon, 31% rayon, 5% spandex
What we like: Very snug and secure fit.
What we don’t: Knee-high design isn’t for everyone; fairly pricey for the amount of wool.
For long-distance trekking, peak-bagging, and other mileage-heavy pursuits, some hikers and backpackers now turn to compression socks to improve blood flow and help with overall support. The jury is still out on the true efficacy of compression technology, but we’ve found that the added snugness does help with minimizing fatigue over long distances (it’s also a plus for those who suffer from chronically cold feet). In this category, Sockwell’s Circulator is a great pick for those looking for a supportive, calf-hugging design that adds an extra dose of security on the trail.
At $30 and with very little merino in the build, the Sockwell Circulator is fairly pricey for the mix of materials you get. Further, the Circulator comes up to just below the knees, which helps with coverage and protection when venturing off-trail but isn’t everyone’s cup of tea. Finally, compression socks in general are more popular among the ski and road cycling communities (where the tech has more of a potential impact on recovery), but some hikers find the boosts in security and added performance worth the slight cost penalty. If you’re regularly putting in the miles and want to try something a little different, give the Sockwell Circulator a look.

Years ago, you might have seen a smattering of cotton and polyester hiking socks on the trails, but merino wool is now the leader far and away. Merino—the namesake wool from a highly prized type of sheep that lives predominantly in harsh mountain environments, including New Zealand’s Southern Alps—is extremely comfortable, wicks moisture well, and does a nice job of breathing and regulating temperature. It also takes much longer to build up stink, allowing for extra days of wear on a hiking or backpacking trip (how many days is up to you). Cotton, on the other hand, is heavier, absorbs moisture, and doesn't dry when wet. And while polyester may keep you cool, we are yet to find an option that doesn't start stinking rather quickly.
That said, it’s important to note that even merino wool hiking socks aren’t 100 percent merino: You’ll notice in our picks above that the percentage of merino is between around 30 and 80 percent, with the rest being a blend of nylon and spandex. The density varies by sock as well—just because the REI Merino Wool Ultralight Crew socks are 72 percent merino doesn’t mean they are the highest-quality option. Darn Tough's Micro Crew Cushion socks, for example, are around 61 percent merino but the weave is denser, and they tend to hold their shape better and last longer.
In general, we strongly prefer merino wool over polyester. Merino is known for its natural antimicrobial properties, whereas polyester socks hold stink in a serious way (this alone has us firmly in the merino camp). Moreover, merino wool is a naturally sourced material, whereas polyester is made from plastic fibers.
That said, polyester does have a couple of redeeming qualities. For one, it is highly durable, lasting longer than pure merino. In addition, it does not soak up water to the extent that merino does, allowing it to dry faster. And some of the Coolmax models like the Darn Tough Coolmax Micro Crew provide excellent breathability for adventuring in hot conditions. Finally, for those looking for synthetic material that is kind to the environment, check out Coolmax EcoMade (seen in the REI Co-op Coolmax EcoMade Lightweight), a polyester made from recycled plastic bottles.
Sock manufactures offer a variety of thicknesses designed for everything from summer hiking to mountaineering. For the purposes of this section, we are evaluating overall sock thickness (ultralight, lightweight, midweight, etc.) and not the strands themselves as described above. For three-season hiking, backpacking, and casual wear, we recommend the lightweight versions, which provide solid levels of padding and insulation for temperatures from approximately 40 degrees to 80 degrees Fahrenheit. They also wear well around the house and under your favorite pair of shoes, provided there’s enough room.
If you’re hiking in hot places like Utah or Arizona in lightweight hiking shoes, you may want to consider an ultralight hiking sock. The downside is that ultralight socks are thin on the foot and offer significantly less padding and blister protection than lightweight and midweight socks. Another option for summer hikers is a lightweight hiking sock in a 1/4 height, which has less leg coverage and a more airy feeling but the same cushion on the foot. For winter hiking and mountaineering, the major brands make midweight and heavyweight options that provide much more warmth than the lightweight versions, like Darn Tough’s heavyweight Hiker Boot Full-Cushion and Smartwool’s Classic Hike Extra Cushion Crew. Keep in mind that these burly socks are overkill for three-season hiking and casual use. In normal temperatures your feet will sweat, and despite merino’s impressive ability to wick moisture, you will get unwanted dampness.
Crew is the most common hiking sock height, which extends 6 to 8 inches above the heel and at a least a couple of inches above just about any pair of hiking boots. We feel that this is the optimal height for hiking: Crew socks don’t make you excessively hot and offer some added lower leg protection from brush and rocks. Hiking pants can be quite thin, so the extra cushion is helpful, and particularly if you’re wearing shorts on all but the easiest of trails, crew is the way to go.
Quarter (1/4) height hiking socks cover the heel and ankle but don’t extend up the leg as far as crew socks. Minimalist hikers and those out in the heat of summer may prefer 1/4 socks like the Darn Tough Quarter Cushion, which work well so long as you aren’t wearing boots with high ankles (you may end up feeling some friction) and don’t need protection from abrasions. This style also crosses over well to wear with running shoes.
Even lower than quarter-length are no-show socks. If you’re wearing low-riding hiking or trail-running shoes, a no-show sock should rise just above the collar and still offer padding and protection between your ankle and shoe. However, keep in mind that no-show socks have a greater chance of letting in trail debris like gravel or dirt, and a poor fit could lead to rubbing along your heel and ankles. We prefer 1/4 socks for most of our outdoor endeavors simply for the added coverage, but shorter socks, like Balega’s Hidden Comfort, are undoubtedly lower-profile and have appeal for those looking to minimize bulk.
As their name implies, over-the-calf socks rise higher than crew socks to just below the knee. By covering more of your leg, they can be a great option for hiking off-trail through high grass or brush, or in cases where you need extra warmth. On our list above, Sockwell’s Circulator Compression Socks fall just below the knee and add a boost in security around the calf, which some find helpful for muscle recovery and maximizing circulation. However, in most scenarios, crew socks should provide ample coverage and protection.
Compression is a bit of a buzz word among outdoor athletes these days, praised for its ability to help with muscle recovery and reduce overall fatigue. In the hiking realm, some trekkers find compression socks helpful when covering long distances or traveling in cold weather, as the added support can help alleviate soreness and encourage blood flow. We included one compression model on our list above—the Sockwell Circulator—which is a nice match for those who want a bit of added snugness and security on the trail. You can expect to pay a bit more for dedicated compression models—and they’re certainly not for everyone—but some may find the potential benefits worth the investment.
After countless miles on the trail, our observations on hiking sock comfort are as follows: Darn Tough makes the best overall hiking socks taking into account comfort and durability, but they have a slightly thicker and denser feel than Smartwool. This isn’t a bad thing—Darn Tough socks can really take a beating (hence the name). Smartwool hiking socks have great breathability and an excellent fit, particularly the Performance (formerly the PhD) line, but over the years, we’ve had more issues with durability and holes. There also are a handful of up-and-comers like Stance that are a slight step down in overall comfort but have more attractive styling that many hikers appreciate. Last but not least, brands like REI aim for more value-oriented buyers, and the snugness and durability can’t match Darn Tough and Smartwool.
It’s incredible how many times we’ve put our hiking socks through the washer and dryer and had them come out feeling and fitting like new. Durability is brand specific and we’ve seen changes throughout the years even among the same manufacturers. Smartwool, for example, has soft and comfortable socks but we’ve noticed holes developing more quickly than they used to (the recent change to Indestructawool has helped). Our REI socks have held up fairly well, but they seem to loosen over time. Darn Tough socks aren’t the softest but we have had no issues to date with holes with either their Micro Crew or Quarter Cushion, which is frankly pretty amazing. Virtually all wool socks have issues with pilling, which can be lessened by line drying.
No matter the brand, you will be pleasantly surprised with how long a $20 pair of hiking socks can last. If you have a few pairs in the rotation, you can expect most hiking socks to last at least a couple of seasons if not more. We have multiple pairs in our sock drawer that are used both for outdoor adventures and around town, and we rarely have to replace them.
The focus on sustainability has been increasing in the outdoor industry over the past several years, and hiking socks are no exception. In this category, there currently are two key trends: wool that is certified to the Responsible Wool Standard (RWS) and the use of recycled materials. The former indicates that sheep were treated humanely and in accordance with strict animal welfare and environmental standards (on our list above, REI’s Merino Wool Ultralight uses RWS-certified wool). We’ve also begun to see more companies utilizing recycled materials, including Smartwool’s recently updated Performance line that uses recycled nylon and socks made with CoolMax EcoMade, which is a polyester made from recycled plastic bottles. All in all, we appreciate these efforts and are eager to see more brands come on board.
Many companies sell both men’s- and women’s-specific socks, but in most cases, there are no major performance differences between the two. Women’s socks often differ in color and are offered in smaller sizes in general, but otherwise sport the same overall design and fit as their men’s or unisex counterparts. Overall, it’s best to simply make your decision based on sizing rather than nailing down if the sock is unisex or women’s-specific.
We’ll start off by saying that we think liner socks should be a last resort for those who suffer from blisters or uncomfortable rubbing. Before going this route, it’s better to pick up a quality pair of moisture-wicking wool or synthetic socks (rather than cotton) and nail down a well-fitting shoe or boot. Why? First and foremost, liner socks can give a somewhat sloppy feel—it’s another layer between your foot and your shoe and there can be some unwanted movement as a result. Liner socks are also notably thin, which translates to a shorter lifespan than your regular socks and more care required. In the end, with the quality of hiking socks improving so significantly, liner socks are becoming less and less common for hiking and backpacking.
All that said, if you’ve exhausted all other options and want to give them a try, a liner sock could be a viable way to boost padding and protection between your foot and shoe. Worn under your hiking socks, liner socks bear many similarities to the models above but are thinner and generally cost around half the price. If you want to try them out, make sure to pair your liner and sock accordingly: You should use a merino liner with a merino sock or a synthetic liner with a synthetic sock. Alternatively, socks like the Wrightsock Coolmesh II above have two-part designs that essentially blend the two components together, and Wigwam’s Arbor NXT Crew takes a similar approach by knitting an inner lining into the design. And as a final solution, blister dressings like Moleskin or tape can be an effective way to treat or prevent hotspots.
Hiking socks have gotten fairly expensive in recent years, which has made their warranties a noteworthy part of the buying process. The long-time leader in this department is Darn Tough: Their lifetime, unconditional guarantee means you can get a replacement pair sent for reasons ranging from complaints about comfort to a hole developing in the heel. Other popular brands like Stance, Feetures, and Farm to Feet also have strong lifetime guarantees, with the latter two brands also offering full refunds (with proof of purchase). The next tier down are warranties with a set timeframe, including Smartwool (two years) and REI Co-op (one year). Finally, you’ll often find shorter or more limited policies from budget-oriented brands. In the end, while we wouldn’t base our final decision solely on the guarantee, it’s something to have in mind.
For most merino wool products, we recommend washing in cold water and line drying. The directions vary by manufacturer and some claim merino can be machine dried, but we find that this significantly shortens the lifespan. However, merino wool hiking socks—along with their polyester counterparts—are one of the few items that we often throw in the dryer with our regular clothes. They just don’t tend to have the same durability issues as other merino products and the warm dryer has a nice way of getting the socks back to their original shape. We think you can go either way here in terms of line or machine drying, but keep in mind that you may get slightly more pilling and shrinkage in the dryer.
