Darn Tough Hiker Micro Crew Midweight Hiking Socks Review
May 18th, 2026
Home > Gear Reviews > Footwear
Over tens of thousands of miles of testing with dozens of hikers in dozens of climates, we think the best hiking socks you can get are men's and women's Darn Tough Hiker Micro Crew Midweight hiking socks. It hits that “Goldilocks” sweet spot of cushioning: they aren’t so thin that you’ll put holes in them in a week, but they’re also not so thick that you’ll need to buy shoes or boots a half size larger.
The Hiker Micro Crew Midweight is the most popular model on Darn Tough’s website, and it’s a top seller on REI and Amazon. Best yet, it comes with a Lifetime Guarantee, considered the most generous in the entire outdoor industry. And, the Hiker Micro Crew has been tested by nearly two dozen Treeline Review writers and testers, and there are a lot of Darn Tough lovers in our midst.

The Darn Tough Hiker Micro Crew Midweight is made with a blend of naturally antimicrobial merino wool that keeps odor at bay. It has just the right amount of stretch to fit better than a glove over your feet. This means in tens of thousands of miles of testing in temperatures from the teens to the above 100°F, blisters are rare to non-existent. Besides the durability, this is a main reason the Darn Tough Hiker Micro Crew Midweight is the most popular hiking sock for thru-hikers.
The Darn Tough Hiker Micro Crew Midweight is one of our favorite pieces of gear we’ve tested of any category, not just hiking socks and is part of a new series we're running on our favorite gear items ever.
For our Favorite Gear of the PCT article, multiple writers pitched Darn Tough socks—and they drew straws for who got to write about them. It's also our recommended gift for Hikers and Backpackers.
We really struggle to find something we don’t like about the Darn Tough Hiker Micro Crew Midweight aside from the price. The first time you see the price, it can raise eyebrows. But once you put them on and hike a hundred or thousand miles in them, it is clear they are worth it, and, like me, you'll find yourself with an entire drawer-full of these socks.

What we liked
Tight weave
Perfect fit
Comfort
Durability
Perfect amount of stretch
Retain shape at end of day
Lots of fun colors and patterns (including Close Encounters)
Lifetime warranty that is easy and actually works (we've done it!)
What we didn’t like
Not as soft as alpaca hiking socks (but it isn’t itchy)
Darn Tough lists nearly every pattern in the Micro Crew Cushion line as a different product, so it makes it difficult to see all the options in this height and weight at the same time (example: Celeste, Northwoods, Solid Colors, Mirror Lake, and Treeline all are listed as separate styles).
How we tested
Testing the Darn Tough Hiker Micro Crew Midweight socks on the Loo Wit Trail.
°We tested the Darn Tough Hiker Micro Crew Midweight hiking socks over tens of thousands of miles with dozens of hikers from below freezing to 100°F on thru-hikes of the Appalachian Trail and Pacific Crest Trail.
More than a dozen Treeline Review testers have used the Darn Tough Hiker Micro Crew Midweight socks on the Triple Crown Trails (Pacific Crest Trail, Continental Divide Trail, and Appalachian Trail), Pacific Northwest Trail, Great Divide Trail (twice), Tahoe Rim Trail, Arizona Trail, Grand Enchantment Trail, Idaho Centennial Trail, Blue Mountains Trail, among others.
We also tested the Micro Crew Midweight side by side with other socks for our Best Hiking Socks guide. We evaluated fit, blister-free comfort, thermoregulation, and durability.
Based on all our hiking and testing, we’ve also written the definitive guide, How to Take Care of Your Feet When Hiking and Backpacking.
Performance in the field
Fit, Stretch, And Comfort
What we like about the Hiker Micro Crew Midweight merino sock is that they have the perfect amount of stretch. I purchased these socks and have hiked thousands of miles in this model. Whether in the hot desert, snow-covered mountains, or on long walks around the city, they’ve never slipped, sagged, or bunched up. At the end of a long day of hiking, they never feel loose or stretched out.
The 2% spandex—not too much or too little—makes the socks fit so well that they feel as if they were custom-made for my feet. And most impressively, they keep that perfect amount of stretch even after years of use.
Weave And Breathability
Another thing I like about the Darn Tough Hiker is that the fabric is tightly woven for support and staying power, but it isn’t so tightly woven that it doesn’t breathe well. My feet definitely sweat while hiking in temperatures over 80°F, but they never feel sweaty when I’m hiking in the Hiker Micro Crew Midweight. This is a testament to the great wicking power of Darn Tough’s yarn and just the right weave.
Moisture-Wicking
The Darn Tough Hiker Micro Crew Midweight manages moisture incredibly well, which is important because moisture is a major contributor to blisters. I’ve never gotten a blister while wearing Darn Tough socks. This is in contrast to other merino wool socks I’ve purchased and hiked in, like the Icebreaker Hike+ Light Crew—where my feet felt hot and moist and ultimately formed blisters.
Thermoregulation
The Darn Tough Hiker Midweight socks also stand out for their thermo-regulating capabilities. I’ve taken these socks on 1,600 miles of challenging conditions through the Canadian Rockies, with temps in the upper 30s F, heavy rain, and river fords. My feet stayed warm even while wet. While putting those wet socks back on in the morning was not a pleasant task (and wouldn’t be for any sock), once the heat from my feet warmed the socks back up, they felt fine.
On the other hand, I’ve also hiked 1,600 miles through the Arizona desert on the Arizona Trail in the Hiker Micro Crew Midweights and never felt like my feet were too hot. These socks are almost like magic.
Durability And Warranty
All these features are fantastic, but what has kept me coming back to the Darn Tough Hiker Midweight is its durability. While we also like the Darn Tough Light Hiker, the midweight is the tougher sock. You can read our review of the Light Hiker below.
I can easily get 600 miles out of a pair of midweights before I start to see signs of wear. They easily outlast most pairs of shoes.
When I do get a hole, it’s usually in the bottom—the heel is reinforced, so I’ve never gotten a hole in the heel. But I can send them back to Darn Tough under their incredible warranty program. Once they receive the socks I’ve returned, they send me a code to use on their website to buy a replacement pair—any size, color, or style that I want. It’s almost too simple.
Sustainability
Darn Tough’s merino wool supply is now 100% RWS-certified. The Responsible Wool Standard (RWS) is an emerging new standard that establishes best practices for animal welfare, land management, and worker welfare. It’s similar to the better-known outdoor certification, the Responsible Down Standard. Its goal is to bring sustainability and human and animal welfare into all levels of the supply chain, from the farmers and traders to the yarn spinner to the fabric manufacturer and sewers.
Multi-Packs offer value
Another benefit of the Hiker Micro Crew Midweight is that, unlike most high-end socks, they are available in multi-packs. There’s a men’s and women’s 2-pack, as well as a women’s patterned 3-pack.
Fit for wider calves and feet
Those with larger ankles report that the crew length doesn't work for them. If that’s you, we recommend the quarter crew length for these socks. And of course, if blisters between your toes bother you, we’d direct you towards the Injinji Trail Midweight socks. For everyone else, we’d say the Darn Tough Hiker Micro Crew Midweight Cushion is the best hiking sock out there.
Other Heights And Fabric
While we think the merino version is the best, wool—or even a wool blend—isn’t for everyone. Darn Tough makes this model in COOLMAX, which is one of our favorite non-wool hiking socks.
The Hiker Micro Crew Midweight Cushion is also available in quarter and boot lengths. So even if the micro-crew isn't your favorite height, you can get all the benefits at a height that works for your ankles and calves.
Darn Tough vs. Smartwool hiking socks
There are a few differences between Darn Tough and Smartwool hiking socks, including sizing, warranty length, materials, and price. Men’s Smartwool sizing bands cover 3 ½ shoe sizes in each sock size (e.g., men’s 9-11.5), while Darn Tough sizing covers 2½ shoe sizes (e.g., men’s 8-9.5) in each sock size. We think that with Darn Tough’s tighter size bands, you can get a sock that really fits you well.
Smartwool's warranty is also only 2 years, compared to Darn Tough's lifetime warranty.
Similar Hiking Socks
Darn Tough Midweight vs Darn Tough Light Hiker
Material: 54% nylon, 43% merino, 3% Lycra
Cushion: Light
Length options: No-show, Micro crew, Quarter, Crew
Sizing: Women’s S-L (US 4.5-11.5) and Men’s S-XXL (US 5.5-17)
The Darn Tough Light Hiker has many features we liked in its medium-cushioned sibling, but it was less durable. We also think most hikers—regardless of how rocky their trail is or how heavy their pack is—benefit from the extra cushion in the midweight Darn Tough that we recommend. Still, the Light Hiker is a great sock, and hikers in warmer climates or with lighter pack weights may prefer it, especially the ¼-height version.

Darn Tough Hiker Micro Crew Midweight vs. Smartwool Performance Hike Targeted Cushion
The Smartwool sock most similar to the Darn Tough Micro Crew is the Performance Hike Targeted Cushion.
Smartwool and Darn Tough's material compositions differ between their cushioned and less cushioned socks and between men's and women's socks. Still, in general, Darn Tough has slightly more wool and less nylon than Smartwool. Smartwool is 54% merino wool/43% nylon/3% elastane, while Darn Tough's is 59% merino wool/39% nylon/2% LYCRA spandex.
The Smartwool Performance is $3 less expensive than the Darn Tough.

Are Darn Tough socks worth the price?
Yes, we definitely think Darn Tough socks are worth the price. After testing dozens of socks over thousands of miles, our team agrees that Darn Tough socks are the best for fit, comfort, and durability. Darn Toughs are generally considered the best socks for thru-hiking and other long-distance hiking and backpacking trips where durability and blister control are extremely important.
Should I buy the Darn Tough Hiker Micro Crew Midweight?
Buy if:
You hike or backpack any distance
You want a pair of socks that will last for life
You hate blisters
You don't want sweaty or stinky feet
You want to give someone a gift they will really appreciate (that lasts for life)
Skip if:
You have wider calves or feet. Opt for Darn Tough's sister brand, Wide Open Socks, instead. These offer the same material and fit, just designed for wider feet (EE to EEE).
You are using your socks for running. These socks are designed for hiking, and while we have a writer who has run (and won) ultramarathons in them, you'll still probably be better served by dedicated running socks (see our running socks guide for recommendations).
You're on a budget and can't bring yourself to pay this much for socks.

FAQ
-
Yes, Darn Tough Micro Crew Midweights fit true to size. However, some hikers prefer sizing down if they are between sizes.
-
Micro crew is ~8.5" from heel to cup, depending on your shoe size. For most hikers, this is tall enough to provide ankle protection and support while wearing boots. It sits 3-4" below the bottom of the calf muscle for most people.
-
Darn Tough Micro Crews work for most people with wide and narrow feet. If your feet and calves are very wide, consider Darn Tough's Wide Open socks instead.
-
No, Darn Tough socks are pre-shunk. Darn Tough says like a pair of jeans, they may feel snugger right after a wash but they will stretch right out.
-
Most people find Darn Tough socks are not too tight around the calves. People with wider calves may prefer Darn Tough's Wide Open socks instead.
-
Yes, the Darn Tough Micro Crew Midweight is the sock dozens of our testers and writers have used for literally tens of thousands of miles of hiking, including thru-hikes of the Appalachian Trail and Pacific Crest Trail.
-
Yes, the merino wool in Darn Tough Micro Crew Midweight socks regulates temperature so doesn't feel too hot in summer. We have worn these socks in 100F temperatures while hiking.
-
Yes, we like the Darn Tough Micro Crew Midweight socks for warmer winter hikes. For colder temperatures, we prefer more heavy duty Darn Toughs. See our Best Winter Socks guide for more recommendations.
-
Yes, a good pair of hiking socks has no seams that can cause hot spots and blisters while hiking. They can also wick away moisture associated with blisters.
-
We like the Darn Tough Micro Crew socks for both backpacking and day hikes. Some ultralight backpackers may prefer a shorter height version, the Darn Tough Quarter Cushion, which has the same cushion but a shorter height designed for using with trail running shoes.
-
Not really. We are often surprised by how free of odor these socks stay, even after multiple days of wear. If you are going through swamps or sweating a lot, you may notice odor. But for everyday use, especially when not hiking, we find we rarely need to wash these socks.
Why you should trust us / About the author
I’ve logged tens of thousands of miles during my thru-hiking career—all of them while wearing socks. Some of my favorite long-distance hikes (ok, they’re all my favorite) include the Triple Crown (Pacific Crest Trail, Continental Divide Trail, and Appalachian Trail), Pacific Northwest Trail, Great Divide Trail (twice), Tahoe Rim Trail, Arizona Trail, Grand Enchantment Trail, Idaho Centennial Trail, Blue Mountains Trail, among others.
On my first thru-hike, I didn’t pay as much attention to socks as I should have—and I paid the price. I got blisters everywhere—between my toes, on my lower ankle, at the bottom base of my toes. I even had a blister under a callus!
As a result, I’ve become mildly obsessed, searching for the perfect pair of socks ever since. Our overall winner, the Darn Tough Hiker Micro Crew Midweight, is the closest thing I’ve found.
All of our opinions and recommendations are based on personal purchases of the models that made our shortlist and our own experience hiking thousands of miles with the models we describe.
