We tested dozens of pairs. These are the socks worthy of a spot in your drawer.

Runners obsess over every detail of their running shoes to make sure they have comfort dialed for every step. But many of us will still jam an old cotton sock between that pricey shoe and our feet. The humble running sock, however, plays an important role in keeping you dry and warm (or cool).

First off, avoid cotton at all costs. Sure, you could safely make it through a 3-mile recovery jog in running socks that came from a 12-pack, but on hot or wet days, you’ll find cotton absorbs an incredible amount of water and easily causes blisters.

Merino wool, on the other hand, is a fiber you can wear year-round thanks to its ability to regulate temperature, move moisture, and resist odors. You’ll find it in many pairs of performance running socks. Most, however, use a mix of synthetic fabrics—nylon, polyester, and spandex—which offer good value and durability, and prevent irritation that can lead to blisters.

The thicker your running socks, the more cushioning you’ll get with each step. The extra material can also take up more room in your shoes to make the fit feel more secure.

If you like a soft shoe, pair it with a sock that has thick cushioning underfoot for a supremely plush experience. If your shoe fits a little loose—but not enough to go up half a size—opt for a thicker sock to take up some of that volume.

Unless you’re hitting the trail (where a tall sock will help keep dirt, brush, and ticks away from your skin), sock height is a matter of personal style and comfort. Crew-length running socks have made a comeback in recent years, but the cut offers little performance value—although one could argue that because of the extra height, the sock won’t slip into your shoe like a no-show sometimes can.

Our team of experienced testers spent many hours and miles running year-round to evaluate how these socks fared in a variety of conditions—from hot and humid track workouts to bitter cold runs through the snow to rainy slogs on the trail. We also noted how well these running socks held up between multiple wears and washes.

In addition to gathering detailed on-foot impressions, we tested several socks on this list with a vertical moisture-wicking test, a common method for measuring how textile fabrics hold, distribute, and release water. This test assesses how well each sock handles sweat and moisture by providing a side-by-side comparison of how quickly dyed water soaks into a material, passes through it, and eventually evaporates.

For ours, we cut 6-by-1-inch strips from the socks’ fabric and hung them from a stand, with the lower end dipped in blue water. We measured the amount of time it took for the water to migrate roughly 2 inches up each fabric strip. We also noted how long it took for the socks to dry after they were completely saturated.

The pairs we’ve included in this list are some of the top performers across all of our tests, and we’ve indicated the qualities or conditions in which a specific sock excelled. That said, every running sock here strikes a good balance of odor control, moisture management, comfort, durability, and value for your runs.

The Hidden Comfort still reigns supreme as Balega’s plushest and most cushioned model—it’s one of our all-time favorites for both hammering miles on the roads or treadmill, and winding down with some post-run stretching. However, the potential negative about the Hidden Comfort is that it’s, well, mostly “hidden” inside your shoe. (The heel tab ensures the sock doesn’t slip down your foot, but it doesn’t provide much by way of ankle coverage.)

For that reason, we favor the Enduro for trail runs and during the colder months of the year. The sock is plenty cushioned like the Hidden Comfort, but its taller height options offer more protection from dirt and debris, and also help keep chilly air from nipping at your ankles.

The majority of the Enduro’s cushioning uses Balega’s Drynamix polyester yarn, which feels soft and smooth and wicks moisture away from the foot to prevent blisters.

But when compared to wool socks we’ve tested, it doesn’t perform as well in terms of durability and odor control. Though we haven’t put any holes in the Enduro after seven months of running, Balega only guarantees its pairs for a year.

We’ve long loved Feetures’s socks because of their dedicated left and right fits and seamless construction. Together, those two aspects lead to dialed-in fit and comfort with no baggy toes or irritating seams, but the material itself was always really slippery inside a shoe. Now, the Elite line is built with Tencel, a synthetic fiber made of processed wood that boosts durability. The new Elite also has a very high, 200-needle thread count for that same comfortable fit without the sliding.

The deep heel pocket and snug wrap around the arch ensure the sock stays in place on your foot. None of our testers reported any slipping around in their shoes on runs.

Even runners who preferred no-cushion socks liked Feetures’s plusher offerings. “The inner padding is super soft and a little fuzzy, but overall the sock is still snug, secure, and lightly compressive,” one tester said of the max-cushion Elite. “It feels like a cozy cabin sock meets performance running.” An extra bonus? There’s a rainbow of colors.

Performance socks aren’t cheap, but rest easy knowing that if you ever poke your big toe through this merino sock you’ll get a replacement pair for free. But it’s unlikely you will wear this sock down; we found it to be the most durable, lightweight wool model. Darn Tough uses a high stitch count for the Run Ultra-Light, so it’s velvety soft against your foot and wraps the arch with just enough compression for a secure fit and a smidge of extra support.

“I have a purple and green pair of Darn Tough socks that I’ve been wearing for almost three years, and they’re still as cushy as they were on the first run,” says one tester. “They’re my go-to for 20-milers during marathon training because they stay put and don’t bunch or slide, even when I’m moving for hours and my feet start to swell.” One tester who had a little extra space around the pinky toes thought left-right specificity could make the fit even better.

The Maxus is Swiftwick’s plushest, coziest sock to date. It’s the pair we’ll grab most frequently for Sunday long runs—or days when we know we’ll be spending a lot of time on our feet—and we want to supplement our shoes with as much cushioning as possible. That much hasn’t changed. However, Swiftwick did recently give the Maxus an important update by switching to a new material called Repreve. It’s a recycled fiber that’s more sustainable and saves the plastic equivalent of one water bottle.

Initially, we worried the new construction would impact the socks’ durability and cloud-like softness. Rest assured, after six months of testing, the Maxus is still our dream sock for big mileage. Testers who loved the original model noted no drop in comfort or quality whatsoever.

If you’re seeking a bit more insulation for bitterly cold runs, grab Swiftwick’s Vision Five Winter version instead. Its soft merino-wool-and-nylon construction has kept our toes toasty so far this season, even through a holiday 5K long past sunset. Plus, the taller, 5-inch cuff protects that sliver of skin between the hem of your tights and the top of your shoes.

Even socks with thick cushioning can efficiently wick sweat away from your skin, which helps prevents blisters from forming on your feet. Just take this plush Smartwool pair, for example—it was the top performer overall in our moisture-wicking test. Made from a soft, cozy blend of merino wool, nylon, and spandex, it was also one of the most comfortable we tested, with targeted underfoot cushioning that didn’t feel bulky or take up too much room in our shoes.

Plus, the 56 percent wool construction really cuts down on stink. We found that even after four wears back-to-back, the sock smelled immensely better than standard cotton or polyester models that endured the same sweaty treatment. The only downside was that the Smartwool’s thicker cushioning took longer to dry once it got wet in our follow-up tests, so it’s not the best sock to wear on rainy runs when you’ll be splashing through puddles.

Swiftwick dubs its latest creation, the Flite XT Trail, the “most technically advanced sock for hiking and trail running.” While much simpler socks have also excelled in our tests, this new model proved itself a cut above. The Flite XT Trail builds on the original Flite XT model from Swiftwick. Both pairs have portions of grippy fibrous material beneath the heel and forefoot, which help prevent your foot from sliding around inside your shoe. Combined with snug arch and ankle compression, this lends extra support for lateral movements in agility drills and circuit training—or for dodging rocks, roots, and potholes midrun.

The trail-specific version, however, also incorporates merino wool that naturally controls foot odor and feels a little softer against the skin. All that comes together to make this one of the best socks we’ve run in. The material is thick, durable, and dries quickly after we soaked it in a rainstorm. Plus, there’s enough cushion so you’ll feel a little extra protection on longer runs, but it’s not too heavy or mushy.

“My favorite thing about this sock is how it makes the fit of every running shoe feel a little more locked in,” test editor Morgan Petruny says. “That’s especially helpful in some daily trainers where I have a little too much wiggle room. These socks take up that bit of extra space and grip the shoe’s insole without making my feet feel too cramped or sweaty—the material is durable and thick, but still breathes nicely.”

However, after 15 months of running, we did finally put holes in our test pairs. Petruny says: “While there aren’t any signs of wear on the heels or toes, there’s a small rip on the inside of the ankle. It’s right over the ankle bone where the seams connect the heel cup to the rest of the sock. I only notice it when I pull the socks on, so it hasn’t yet affected their overall performance.”

Test editor Amanda Furrer grabs these socks first when she wants an extra recovery-enhancing squeeze on the run, without wriggling into a pair of knee-highs. “Personally, I’ve not always felt a significant performance boost from compression socks, but the fit and firmness of this pair feels like they’re really doing something,” she says. “It’s amazing they manage to stay up the entire run—no sliding down or bunching. I’ve taken up speedwork and long runs again, so I’d like to believe these help me recover on my easy runs.”

This mid-cut model delivers between 18 and 20 mmHg of compression around the arch and ankle, which is slightly less than what you’ll get from CEP’s taller pairs. Those deliver 20 to 30 mmHg. (Check out our compression socks guide for more on the ideal compression levels for running socks.)

We like it because it supports tired feet and helps promote blood flow, but doesn’t feel uncomfortably snug or restrictive during workouts. Plus, the 4.0 model has a padded and ventilated footbed for some softer cushioning underfoot that also moves heat and sweat away from your skin.

Stance builds apparel that’s all about performance but doesn’t sacrifice style. This means you’re getting premium materials and workmanship with attention to the details—like left- and right-specific fits, antimicrobial finish, and woven channels to let air flow more easily through the cushioning. And with that, you still have the option to spice up your race or daily run with flowers, stripes, camo, Disney characters, and dozens of artist collaborations.

Made from a blend of nylon, polyester, and a pinch of spandex, the sock is smooth but not too slippery; news editor Theo Kahler found the textured footbed and cushioning creates just enough friction to keep him planted inside his trainers. “These socks hugged my arch and heels and didn’t move around at all–almost like a second skin,” says another tester, who wore the no-show height for both runs and HIIT workouts.

Even runners who preferred more plushly cushioned socks were surprised by this thinner model’s support and comfort. “I especially appreciated these socks’ subtle compressive cushion that wraps around the arch,” says one tester, who spins extra miles on the bike during his NYC Marathon training. “For that reason, they’ve also become my go-to pair for cycling. The socks help my cleats feel snugger without constricting my toes or the tops of my feet.”

Don’t worry about whether your socks will match your kit on race day; slip on a pair of Near Earth’s all-black or all-white crews and go. They’re simple and soft, but built to go fast with an extremely stretchy and lightweight construction that breathes well and hugs your Achilles without sagging. We wore The Distance for several 10 milers this winter, both on the treadmill and outside in temps from 40 degrees to below freezing—and most liked the socks’ plush and airy cushioning. It’s just padded enough that it doesn’t feel bulky inside a slim-fitting race shoe, and the compressive arch band feels snug and secure around the midfoot. So, even though the material is a bit slick, we didn’t experience any sliding inside our shoes.

For the socks’ second version, Near Earth dialed in the fit. We found the first version a little baggy in the heel and constrictive around the toes. That’s no longer the case; now there’s comfortable stretch throughout the entire footbed. And, during some unseasonably warm and rainy February runs, the socks’ combo of sweat-wicking nylon yarn and spandex kept our feet blister-free. (The company’s founder sources materials and personally gathers feedback from garment makers and seasoned marathoners in Northern Italy.)

All in all, we’re impressed by the craftsmanship and high quality of The Distance Running Socks. They’re everything you need for any long, pavement-pounding effort.
