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 2021. 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

1. Darn Tough Micro Crew Cushion ($24)

Darn Tough Hiker Micro Crew Cushion socksMaterials: 61% merino wool, 36% nylon, 3% spandex
Cushioning: Light/medium
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

2. Smartwool PhD Run Ultra Light Low Cut ($17)

Smartwool PhD Run Ultra Light Low Cut socksMaterials: 48% merino wool, 47% nylon, 5% elastane
Cushioning: Ultralight
What we like: Light and breathable design is great for summer hiking.
What we don’t: Minimal cushioning impacts comfort on extended trips.

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 PhD Run Ultra Light Low Cut is our favorite. Competitively priced at $17, 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 Ultra Light Low Cut is a nice option for summer when you don’t need serious cushioning.

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 PhD Run lineup, which add more padding around the heel and ball of the foot.

Best Budget/Synthetic Hiking Sock

3. REI Coolmax EcoMade Lightweight Hiking Quarter ($14)

REI Co-op COOLMAX EcoMade Lightweight hiking sockMaterials: 77% Coolmax EcoMade, 22% nylon, 1% spandex
Cushioning: Light
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).

Best No-Show Hiking Sock

4. Balega Hidden Comfort Socks ($14)

Balega Hidden Comfort hiking sockMaterials: 32% Drynamix, 11% nylon, 3% neofil, 2% elastane
Cushioning: Medium
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.

Best of the Rest

5. Smartwool Performance Hike Light Cushion Crew ($23)

Smartwool Performance Hike Light hiking sockMaterials: 56% merino wool, 42% nylon, 2% elastane
Cushioning: Light
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.

6. Darn Tough Quarter Cushion ($19)

Darn Tough Hiker Quarter CushionMaterials: 61% merino wool, 37% nylon, 2% spandex
Cushioning: Light/medium
What we like: Cool and light. 
What we don’t: The lower cut means less protection.

For those who prefer to move fast and light, we love the Darn Tough Quarter Cushion. 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 PhD Run Ultra Light 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 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.

7. Wrightsock Coolmesh II Quarter ($14)

Wrightsock Coolmesh II Quarter hiking sockMaterials: Inner layer: 70% polyester, 26% nylon, 4% Lycra; Outer layer: 71% polyester, 24% nylon, 5% Lycra
Cushioning: Light
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 $15 (both models strike us as a decent value).

8. REI Co-op Merino Wool Ultralight Crew ($16)

REI Co-op Merino Wool Ultralight Crew socksMaterials: 72% merino wool, 26% nylon, 2% spandex
Cushioning: Light
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 PhD Run 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.

9. Injinji Trail Midweight Mini-Crew Socks ($16)

Injinji Trail Midweight Mini Crew hiking sockMaterials: 39% Coolmax, 58% nylon, 3% Lycra
Cushioning: Medium
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.

10. Smartwool Trekking Heavy Crew ($22)

SmartWool Trekking Heavy Crew SockMaterials: 70% merino wool, 29% nylon, 1% elastane
Cushioning: Heavy
What we like: Durable and cozy.
What we don’t: Overkill for most hikers and runs very hot in summer temperatures.

Chances are that if you like Smartwool’s lightweight hiking designs, the Trekking Heavy Crew will make you happy as well. Boasting the thickest padding on our list, these burly socks are made from 70% merino wool 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 (just make sure to take your boot size into account, as these socks add considerable bulk).

As we alluded to above, most people will find the Smartwool Trekking Heavy Crew way too hot for summer outings. This lack of year-round appeal is enough to bump these socks toward the bottom of our list, but they nevertheless are an excellent option for shuttling heavy loads in cooler temperatures. And for a slightly cheaper option that is 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.

11. Darn Tough Coolmax Micro Crew Cushion ($22)

Darn Tough Coolmax Micro Crew Cushion socksMaterials: 37% nylon, 34% Coolmax, 26% acrylic, 2% Lycra, 1% other
Cushioning: Light/medium
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.

12. Swiftwick Pursuit Hike Six Medium ($24)

Swiftwick Pursuit Hike Six Medium hiking sockMaterials: 69% merino wool, 15% nylon, 13% Olefin, 3% spandex
Cushioning: Medium
What we like: Medium thickness and cushioning yet breathable.
What we don’t: Uninspiring looks and high price.

There are a dizzying number of hiking socks on the market, and Tennessee-based Swiftwick throws their hat into the ring with their Pursuit Hike collection. Made in light and midweight thicknesses, the socks have a snug fit around the heel and arch, seamless toe, and durable feel overall. However, their main calling card is the use of moisture-wicking Olefin fabric, which accounts for 13% of the construction and has proven to be particularly functional for high-output activities like trail running (they were a favorite of ours last winter) and backpacking.

We think the Pursuit Hike line is a solid all-around effort, and we especially like the medium-thickness option for its combination of cushioning and breathability. But in a crowded and seemingly ever-growing field, that doesn’t strike us as enough for them to become a big-time player. Plus, Swiftwick’s styling falls on the conservative and rather bland end of the spectrum, which doesn’t help their cause when alternatives like Balega and Smartwool’s latest Performance Hike collection above are more attractive. That said, if its performance characteristics appeal to you and you don’t mind the primarily gray and black colorways, the Pursuit Hike is undeniably a quality offering.

13. Sockwell Circulator Compression Socks ($27)

Sockwell Circulator compression socksMaterials: 32% merino wool, 32% stretch nylon, 31% rayon, 5% spandex
Cushioning: Light
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 $27 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.

Hiking Sock Buying Advice

Hiking Sock Materials

Merino Wool 
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.

Hiking socks (lineup of socks on log)
Most of our favorite hiking socks contain merino wool

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. 

Polyester
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.

Thickness and Warmth

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. 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.

Swiftwick's Pursuit Hike socks offer medium levels of padding

Sock Height

Crew Socks
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. 

HIking sock (height comparison)
Crew and quarter-height socks with low-top hikers

Quarter Socks
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 Smartwool PhD Run Ultra Light Low Cut, 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.

Hiking socks (quarter height with shoes)

No-Show Socks
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.

Hiking socks (no-show socks paired with low hiking shoes)
It's important to ensure that your shoes ride higher than your no-show socks

Over-the-Calf Socks
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.

Hiking Socks (boot cut socks)
Boot-cut socks typically sit mid-calf

Compression Hiking Socks

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.


Comfort

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.

Durability

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.

If you take proper care, hiking socks from leading brands should last a long time

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.

Sustainability

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.

Women’s-Specific Socks

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.

What About Liner Socks?

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 Sock Warranties

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.

Hiking Sock Care

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.
