The short answer
For hiking boots, the Darn Tough Men’s Hiker Boot Full Cushion is CleverHiker’s full-cushion pick, in a men’s cut; for real cold, the Smartwool Mountaineer Classic Edition Maximum Cushion Crew is the sock OutdoorGearLab says is “made for cold, wintry weather”; and for office shoes and sneakers, the Icebreaker Men’s Lifestyle Light Crew is a lightweight everyday crew sold by Amazon.com at the time of writing.
Our verdict
Top Picks: Eight Men’s Merino Wool Socks
Men’s merino socks come down to four published facts: how much merino the maker puts in the yarn, how much cushion sits under the foot, how high the sock rides, and which men’s shoe sizes each sock size covers. This guide compares eight socks on exactly those figures, for the exact size and colour each Amazon button opens, and names the men’s size range the maker gives for that size.
The eight come from Darn Tough, Smartwool, Icebreaker and Farm to Feet, and every one is a merino blend of 60% to 74% merino by its maker’s figures. Five are hiking, mountaineering or ski socks; three are everyday socks for work shoes and sneakers. We have not tested them, and each review grades its evidence, from an independent test of the same model down to maker specs alone. Our guide to women’s merino wool socks covers the women’s styles.

How We Picked Men’s Merino Socks
How this guide was built
built from manufacturer documentation, published third-party reviews and owner reports; we have not tested these products ourselves.
What each sock had to meet
- A merino blend whose maker publishes the percentages for that model, so we can print them instead of guessing.
- Sold as a men’s style, or as a unisex style the maker sizes by men’s shoe size; each review names the men’s size range the maker gives for the linked size.
- On Amazon at the time of writing, new and in stock, with the seller named in each review.
- The Amazon listing’s variant read (size and colour) matches the sock we describe. Where we could not confirm it, the sock is not a pick.
- Warmth, wicking, odour, blister and durability claims are the makers’ claims, and we quote them as such.
Where the evidence comes from, and how it is graded, what r/malefashionadvice posters say about merino socks and seller and stock checks
Where the evidence comes from, and how it is graded
Each review carries an “Evidence” line. “Same series” means an independent reviewer covered the same model but did not say which size or gender they wore. “Maker specs” means we found no independent test and rest on the maker’s page. The independent sources we lean on are OutdoorGearLab, CleverHiker and Pack Hacker; none of them sells these socks. Men’s Health’s merino sock roundup covers mostly dress and lounge socks, none of them the models linked here, so we do not cite it for a pick.
What r/malefashionadvice posters say about merino socks
In the r/malefashionadvice thread “Merino wool socks..? Preferably not ugly..?” (84 comments, March 2025), the top brand reply reads “If you’re in the US, I’d recommend Darn Tough. They’re made in Vermont and have a lifetime replacement warranty.” and the first answer to it is “these are ugly though”. Another poster wrote “I strongly prefer smart wool over darn tough. For whatever reason my darn tough stink at the end of the day just like cotton socks, meanwhile my smart wool can be worn for several days before starting to smell”, and a third finds “Darn tough and many other are just way too thick”. These are a handful of posters, not a test; they are a fair reminder that looks and thickness matter for everyday wear.
Seller and stock checks
We read each listing’s variant, seller and stock on Amazon on 2026-10-29. Both Icebreaker picks were sold by Amazon.com. The Darn Tough Hiker Micro Crew and Mountaineering Over-the-Calf were sold by Dearborn Supply, on Darn Tough’s own list of authorized Amazon sellers; the Hiker Boot Full Cushion was sold by SHOEFRENZY, which is not on that list. The Farm to Feet was sold by the outdoor retailer Enwild, and the two Smartwool picks by third-party sellers named in their reviews. Some socks we considered are not picks because we could not confirm an in-stock listing of an exact size on the day we looked, among them the Darn Tough Steely Boot work sock, the Icebreaker Hike+ Medium Crew and the Smartwool Hike Classic Edition Full Cushion Crew. The live price and the “Prices as of” stamp come from Amazon in the table and review boxes, not from us.
Detailed Reviews of the 8 Men’s Merino Wool Socks
Darn Tough Men’s Hiker Boot Full Cushion, Full-Cushion Boot Sock
Darn Tough Men's Hiker Boot Full Cushion
Men hiking or backpacking in boots in cool or cold weather who want a full-cushion merino sock in a men's cut.
$29.90 from AmazonAs of Nov 4, 03:24 UTCVerdict
A midweight, full-cushion merino boot sock in Darn Tough’s men’s sizing, linked in Large Black, that CleverHiker names its full-cushion pick for cool-weather hiking.
Evidence: Independently reviewed, same series. CleverHiker: Hiker Boot Full Cushion, gender and size not stated.
Darn Tough lists the Men’s Hiker Boot Full Cushion (style 1405) as a midweight boot-height sock with full cushion, “terry loops from cuff to toe”, in 66% merino wool, 32% nylon and 2% elastane, and pairs it with “Hiking boots, backpacking boots, heavy backpacks”. It is a men’s style: Darn Tough’s size selector puts Large at men’s 10-12, and its page says “Men’s boot socks average 11 in. from heel to cuff”. Darn Tough’s size chart adds that its “men’s-sized sock styles tend to reach a bit higher on the leg compared to the women’s sock heights.”
CleverHiker names it its full-cushion pick, links both the men’s and women’s versions, and wrote “These are warm, comfy, and cushy socks built for year-round use, from skiing and backpacking to day trips and travel.” It also gives the limit: “These are thick, full-cushion socks, so they’re a bit bulkier than others on this list, and they’re one of our last picks for hot summer hikes.” OutdoorGearLab puts the Darn Tough Hiker Full Cushion, with the same 66/32/2 blend, first in its hiking sock test and writes “The tall, boot-compatible cut is perfect for hiking boots, and the soft, comfortable fibers feel great on your feet.” with the caveat “Typically, the drawback with extra padding is less breathability, and the Darn Tough Hiker Full Cushion is no exception.” Neither source says which size or gender it wore.
Darn Tough’s guarantee, in its own words: “Unconditionally Guaranteed for Life”, and “If these aren’t the longest lasting socks you’ve ever owned, you can return them to us for another pair. No receipt needed, just the pair in question.” Darn Tough adds that socks bought as seconds or irregulars are not covered.
Against the Darn Tough Hiker Micro Crew below, this is the taller, fuller-cushion sock for boots; the micro crew is shorter and cushioned underfoot for hiking shoes as well as boots.
Specs (linked variant)
Pros
- Full-cushion midweight merino boot sock, CleverHiker’s full-cushion hiking pick
- Men’s style with Darn Tough’s men’s sizing and boot-height cuff
- Darn Tough’s “Unconditionally Guaranteed for Life” warranty
Cons
- Thick and warm: CleverHiker calls it one of its last picks for hot summer hikes
- OutdoorGearLab found the extra padding less breathable
- Neither test says which size or gender was worn
- Sold by a seller not on Darn Tough’s authorized Amazon seller list when we looked

Men hiking or backpacking in boots in cool or cold weather who want a full-cushion merino sock in a men’s cut.
- Linked variant: Men’s Large, Black, style 1405
- Men’s size: Large = men’s US 10-12, per Darn Tough

Darn Tough Men’s Hiker Micro Crew, Midweight Micro Crew
Darn Tough Men's Hiker Micro Crew
Men who hike in low or mid hiking shoes or light boots and want one cushioned merino sock for most seasons.
$25.95 from AmazonAs of Nov 4, 03:24 UTCVerdict
A midweight, cushioned merino micro crew in Darn Tough’s men’s sizing, linked in Large Charcoal, of which Pack Hacker writes that few socks are more useful.
Evidence: Independently reviewed, same series. Pack Hacker: Hiker Micro Crew Midweight, gender and size not stated.
Darn Tough lists the Men’s Hiker Micro Crew (style 1466) as midweight with cushion, micro crew height, for “Hiking shoes, hiking boots, backpacking boots”, in 61% merino wool, 36% nylon and 3% Lycra spandex. The Amazon listing’s bullets give 63% merino, 35% nylon and 2% Lycra; we use Darn Tough’s figures. Darn Tough says “Men’s micro crew socks average 8.5 in. from heel to cuff – expect them to show about 6 in. above a low hiking shoe or just above a standard hiking boot.” Large is men’s 10-12 on Darn Tough’s men’s chart.
Pack Hacker wrote “When it comes to versatile socks, few are more useful than Darn Tough’s Hiker Micro Crew Midweight Hiking Socks.” and gives two caveats: “They’re not the most packable socks, but they’re more packable than those that crawl up your calves higher, which is a good compromise.” and “Those who like low-cut socks will find the design restricting”. Pack Hacker does not say which gender or size it used. Our women’s merino sock guide links the women’s version of this sock (style 1903); this is the men’s style.
Darn Tough’s guarantee is the same “Unconditionally Guaranteed for Life” as on the Hiker Boot above.
Against the Hiker Boot Full Cushion, this one is shorter and lighter in cushion; against the Farm to Feet Boulder, the other hiking sock here, it is a micro crew rather than a crew and has less merino by the makers’ figures (61% against 72%).
Specs (linked variant)
Pros
- Midweight cushioned merino micro crew that Darn Tough pairs with hiking shoes and boots alike
- Pack Hacker says the midweight can be worn in hot or cold weather that isn’t extreme
- Men’s style with Darn Tough’s men’s sizing
Cons
- Pack Hacker notes low-cut sock fans will find the height restricting
- The Amazon listing’s fabric figures differ from Darn Tough’s
- Pack Hacker does not say which gender or size it used

Smartwool Mountaineer Classic Edition Maximum Cushion Crew, Maximum-Cushion Crew
Smartwool Mountaineer Classic Edition Maximum Cushion Crew
Large Charcoal · Maximum cushion
Men in winter or insulated boots who want Smartwool's thickest cushion level and a high merino share, and who will keep it for cold days.
$27.00 from AmazonAs of Nov 4, 03:24 UTCVerdict
The thickest cushion level on Smartwool’s own scale, in a 74% merino crew, linked in Large Charcoal, that OutdoorGearLab and CleverHiker both place in the cold-weather slot.
Evidence: Independently reviewed, same series. OutdoorGearLab: Classic Mountaineer Maximum Cushion, size not stated.
Smartwool lists the Mountaineer Classic Edition Crew (SW013300) with Maximum Cushion, which it calls “Our thickest and warmest offering using maximum full sock cushioning”, made in the USA of imported yarn: 74% merino wool, 25% nylon and 1% elastane. It pairs it with hiking, field, work and winter boots. Smartwool sells this crew as a unisex style, listed in both its men’s and women’s ranges, on a unisex chart where Large is US men’s 9-11.5 (women’s 10-12.5); it also makes a separate Women’s Mountaineer Classic Edition, and the Amazon listing is titled Men’s.
OutdoorGearLab names it its cold-weather pick and writes “This sock is made for cold, wintry weather.” Its tester gives the flip side: “When I tried to hike in even moderately warm temps, my feet quickly overheated, and my calves got itchy.” CleverHiker, which links both men’s and women’s versions, wrote “The Smartwool Classic Mountaineer socks (men’s / women’s) have 74% merino wool and are like a cozy cabin for your feet in the coldest conditions.” and warns that “The thick construction means they take their sweet time drying out”. Neither says which size was worn.
Smartwool’s guarantee, in its own words: “So if, for any reason, you aren’t completely happy with your Smartwool® gear within two years of purchasing, we’ll get you into some new gear.” It adds that the guarantee “only applies to Smartwool® products purchased directly from Smartwool or our carefully selected network of authorized retailers”. We could not confirm whether the Amazon seller below is one of them.
Against the Darn Tough Mountaineering Over-the-Calf, the other heavyweight cold sock here, this one stops at crew height and has the independent tests; the Darn Tough covers the leg to below the knee.
Specs (linked variant)
Pros
- 74% merino crew with Smartwool’s maximum cushion, which OutdoorGearLab names for cold, wintry weather
- CleverHiker also places it in its thick, warm slot
- Unisex sizing with a men’s shoe-size column; the Amazon listing is the men’s
Cons
- Too warm for warm weather, per OutdoorGearLab’s tester
- Slow to dry, per CleverHiker
- Sold by a third-party seller whose standing under Smartwool’s guarantee we could not confirm
Who should buy it
Men in winter or insulated boots who want Smartwool’s thickest cushion level and a high merino share, and who will keep it for cold days.
- Linked variant: Large, Charcoal, style SW013300

Icebreaker Men’s Lifestyle Light Crew, Everyday Light Crew
Icebreaker Men's Lifestyle Light Crew
Men who want a thin merino crew sock for the office, travel and everyday shoes rather than the trail.
$21.00 from AmazonAs of Nov 4, 03:24 UTCVerdict
A lightweight 60% merino everyday crew in Icebreaker’s men’s sizing, linked in Large Black and sold by Amazon.com at the time of writing.
Evidence: No independent test; maker specs. Source: Icebreaker.
Icebreaker lists the Men’s Merino Lifestyle Light Crew as “Lightweight, soft, and breathable for everyday comfort”, in 60% merino wool, 38% nylon and 2% Lycra, with an Achilles support, reinforced heel and toe, instep support and a seamless toe closure. It gives a 21.5-micron merino fibre and a weight of 66 g for a Medium. The Amazon listing adds 1% polyester to that blend; we use Icebreaker’s figures. It is a men’s style: Icebreaker’s men’s chart puts Large at US men’s 11-12.5, which covers larger shoe sizes than Darn Tough’s or Smartwool’s Large.
We found no independent test of this sock. The only first-hand comments we read are Icebreaker’s own customer reviews, which we do not count as independent.
Icebreaker’s warranty, in its own words: “We will replace your icebreaker garment within one (1) year from the original retail purchase date, if it has been damaged by defective fabric, stitching or workmanship if returned with proof of purchase from an authorized seller.” It excludes normal wear and tear.
Against the Icebreaker Fine Gauge No Show, its stablemate here, this is the crew-height sock for boots, dress shoes and long trousers; the no-show is for sneakers and loafers.
Specs (linked variant)
Pros
- Lightweight merino crew with reinforced heel and toe, made for everyday wear, per Icebreaker
- Men’s style with its own men’s size chart
- Sold by Amazon.com at the time of writing
Cons
- No independent test we could find; maker specs only
- Icebreaker’s Large covers larger shoe sizes than Darn Tough’s or Smartwool’s Large, so check the chart

Farm to Feet Boulder Lightweight Crew, Lightweight Hiking Crew
Farm to Feet Boulder Lightweight Crew
Large Brown II · Light cushion
Men who hike in lace-up boots in mild weather and want a light crew with a high merino share.
$20.00 from AmazonAs of Nov 4, 03:24 UTCVerdict
A lightweight, light-cushion crew in 72% US merino, linked in Large Brown II, that Farm to Feet designs for lace-up hiking boots.
Evidence: No independent test; maker specs. Source: Farm to Feet.
Farm to Feet lists the Rugged Trail Boulder Light Cushion crew as lightweight, with cushion “light in weight along the base of the foot only”, in 72% US merino wool, 27% US nylon and 1% US Lycra spandex. It says “Full-density padding along the instep and up the calf makes it comfortable to wear with lace-up hiking boots.” Farm to Feet sells the Boulder in both its men’s and women’s ranges on its Standard size chart, where Large is US men’s 9-11.5 (women’s 10-12.5), per the size chart on Farm to Feet’s Boulder product page. The Amazon listing is titled Men’s and filed under men’s.
We found no independent test. Farm to Feet’s page says the Boulder was “Featured in Backpacker Magazine The 10 Essentials for 2014”; that is the maker’s statement about an older listing, not a current test. The Amazon listing names the colour Brown II; Farm to Feet calls it Brown.
Farm to Feet’s guarantee, in its own words: “We can’t claim that socks will last a lifetime, no sock will! However, if you are not completely satisfied with the durability or performance of your Farm to Feet® socks, then please follow the steps below and we will send you a replacement.”
Against the Darn Tough Hiker Micro Crew, the other hiking sock for warmer months here, the Boulder is a crew with the higher merino share by the makers’ figures and cushion only under the foot; the Darn Tough is the shorter micro crew.
Specs (linked variant)
Pros
- 72% US merino crew with light cushioning underfoot, per Farm to Feet
- Instep and calf padding the maker designs around lace-up hiking boots
- Sold by an outdoor retailer rather than an unknown seller
Cons
- No independent test we could find; maker specs only
- Low stock on the linked listing when we looked

A heavyweight, full-cushion merino sock that reaches to just below the knee, linked in men’s Large Smoke, from the line Darn Tough calls its warmest.
Evidence: No independent test; maker specs. Source: Darn Tough.
Darn Tough lists the Men’s Mountaineering Over-the-Calf (style 1955) as heavyweight with full cushion, in 73% merino wool, 25% nylon and 2% elastane, for “Mountaineering boots, hiking boots, winter boots”. Darn Tough says of its heavyweight socks “Our warmest socks – heavyweight socks regulate heat, transfer moisture, and provide steady comfort in cold weather.” and that “Men’s over the calf socks average 17 in. from heel to cuff – expect them to cover the leg to just below the knee.” The Amazon listing calls the cushion “Extra Cushion”; Darn Tough’s current page says Full Cushion. Large is men’s 10-12.
Related guide: Best Warm Weather Hiking Socks: 8 Picks Compared
We found no independent test of this model. Darn Tough’s “Unconditionally Guaranteed for Life” applies, as on the other Darn Tough picks.
Against the Smartwool Mountaineer, the other heavyweight cold sock here, this one is taller and covers the calf under a tall boot or ski-style shell; the Smartwool stops at crew height and has the independent tests behind it. Against the Smartwool Ski, the other over-the-calf sock, this is the heavier, full-cushion option.
Specs (linked variant)
Pros
- Heavyweight full-cushion merino that Darn Tough pairs with mountaineering and winter boots
- Over-the-calf height that Darn Tough says reaches to just below the knee
- Men’s style with Darn Tough’s men’s sizing and lifetime guarantee
Cons
- No independent test we could find; maker specs only

Smartwool Men’s Ski Targeted Cushion Over the Calf, Ski Over-the-Calf
Smartwool Men's Ski Targeted Cushion Over the Calf
Men who ski or snowboard and want a merino sock cut for the shin and calf of a ski boot.
$32.00 from AmazonAs of Nov 4, 03:24 UTCVerdict
A 60% merino over-the-calf ski sock with cushion placed where a ski boot presses, linked in Large Black.
Evidence: No independent test; maker specs. Source: Smartwool.
Smartwool lists the Ski Targeted Cushion Over The Calf (SW001910) in its Standard Fit, made in the USA of imported yarn: 60% merino wool, 38% nylon and 2% elastane. It describes “Indestructawool™ durability technology”, knit into high-impact wear zones, and a “4 Degree™ Elite Fit System” with stretch and mesh zones. Its size guide puts Large at US men’s 9-11.5 for calves up to 16.5 in around; the Amazon listing is titled Men’s and filed under men’s.
We found no independent test we could read. Smartwool’s page says the sock was named “Best Overall Ski Socks” by GearJunkie (2025-2026); GearJunkie’s page did not load for us, so that is the maker’s statement, unverified. Smartwool’s two-year guarantee applies to purchases from Smartwool or its authorized retailers; we could not confirm whether the Amazon seller below is one of them.
Against the Darn Tough Mountaineering, the other over-the-calf sock here, this one is thinner with targeted rather than full cushion, which suits the close fit of a ski boot; the Darn Tough is for hiking and winter boots.
Specs (linked variant)
Pros
- Over-the-calf merino ski sock with cushioning and mesh zones mapped for ski boots, per Smartwool
- Reinforced high-wear zones, per Smartwool
- Size guide gives men’s shoe sizes and a calf limit

Best Men’s Wool Socks by Use
For hiking boots and backpacking
Picks: Darn Tough Men’s Hiker Boot Full Cushion, Farm to Feet Boulder Lightweight Crew.
The Darn Tough is CleverHiker’s full-cushion pick; the Farm to Feet is the lighter crew, cushioned only under the foot, for milder days. If you are also choosing what to wear above the boot, our guide to cold weather hiking pants covers that layer.
For hiking shoes and trail runners
Picks: Darn Tough Men’s Hiker Micro Crew.
Darn Tough pairs the micro crew with hiking shoes and boots alike. If your trail shoes are low-cut runners, our guide to value trail running shoes covers the shoe side.
For cold weather, snow and skiing
Picks: Smartwool Mountaineer Classic Edition Maximum Cushion Crew, Darn Tough Men’s Mountaineering Over-the-Calf, Smartwool Men’s Ski Targeted Cushion Over the Calf.
The Smartwool Mountaineer is the crew with the independent cold-weather tests; the Darn Tough Mountaineering covers the calf in a heavyweight full cushion; the Smartwool Ski is shaped for ski boots. If you are choosing boots for cold days too, our guide to lightweight insulated hunting boots covers boots made for cold days.
For everyday wear, work shoes and travel
Picks: Icebreaker Men’s Lifestyle Light Crew, Icebreaker Men’s Lifestyle Fine Gauge No Show.
Both are thin, lightweight merino blends Icebreaker makes for everyday wear: the crew for shoes worn with trousers, the no-show for sneakers and loafers. Both were sold by Amazon.com when we looked.
Choosing Men’s Merino Wool Socks: Sizing, Merino Share and Cushion
Men’s, women’s and unisex sizing
Darn Tough and Icebreaker make separate men’s styles with men’s size charts; Smartwool sizes the Mountaineer on a unisex chart keyed to men’s and women’s shoe sizes and sells a separate women’s version; Farm to Feet sells the Boulder in both ranges on a Standard chart. The same letter does not mean the same foot: a Large is men’s 10-12 at Darn Tough, men’s 9-11.5 at Smartwool and Farm to Feet, and men’s 11-12.5 at Icebreaker. Darn Tough says to size up if you fall between two sizes. On fit, OutdoorGearLab writes “Consider a male-specific sock if you have a wider foot and women’s socks don’t fit well.”
Merino share and “100% merino”
None of the eight is 100% merino: the makers list 60% to 74% merino, with nylon and a little elastane or Lycra for strength and stretch. Pack Hacker’s view is that “100% Merino wool socks will perform better in the categories we just reviewed, but will also be more expensive.” The highest merino shares here are the Smartwool Mountaineer (74%), the Darn Tough Mountaineering (73%) and the Farm to Feet Boulder (72%), by the makers’ figures.
Cushion and height
Each maker uses its own scale (Darn Tough “Cushion” and “Full Cushion”, Smartwool “Targeted” to “Maximum”, Farm to Feet “Light Cushion”), so compare within a brand rather than across brands. Heights run from no-show (Icebreaker) through micro crew and crew to boot (Darn Tough Hiker Boot) and over-the-calf (Darn Tough Mountaineering, Smartwool Ski). Darn Tough’s chart notes that its men’s styles tend to sit a little higher on the leg than its women’s.
Warranties
Each review quotes its maker’s own warranty or guarantee wording. The terms are set by each maker, and some apply only to purchases from the maker or its authorized sellers, so read the maker’s page before you rely on it and keep your Amazon order details.
Frequently Asked Questions
Q. What are the best merino wool socks for men?
It depends on the shoe. For hiking boots, CleverHiker names the Darn Tough Hiker Boot Full Cushion its full-cushion pick; for real cold, OutdoorGearLab calls the Smartwool Mountaineer “made for cold, wintry weather”; for everyday shoes, the Icebreaker Lifestyle Light Crew and Fine Gauge No Show are Icebreaker’s lightweight men’s styles. Choose the height and cushion for your footwear first.
Q. What are the best wool socks for men in winter?
Among the picks here, the heavyweight, high-cushion ones: the Smartwool Mountaineer Classic Edition Maximum Cushion Crew, which Smartwool calls its “thickest and warmest” cushion level, and the Darn Tough Mountaineering Over-the-Calf from the heavyweight line Darn Tough calls its warmest. Both are thick socks.
Q. Are 100% merino wool socks better?
None of the socks here is 100% merino; the makers blend 60% to 74% merino with nylon and a little elastane or Lycra. Pack Hacker says 100% merino socks perform better but cost more. We have not tested durability ourselves, and the makers do not publish lifespan figures.
Q. What size merino socks should a man buy?
Use the maker’s chart for your shoe size, not the letter size. A men’s US 11 is a Large at Darn Tough (10-12), Smartwool (9-11.5) and Icebreaker (11-12.5), but a men’s US 9 is a Medium at Darn Tough (8-9.5) and Icebreaker (9-10.5) and a Large at Smartwool. Darn Tough says to size up if you fall between two sizes.
Q. Are men’s and women’s merino socks different?
Often in size range and height. Darn Tough says its men’s-sized styles “tend to reach a bit higher on the leg” than its women’s, and OutdoorGearLab says women’s socks typically have a narrower toe box and heel. Our guide to women’s merino wool socks covers women’s styles.
Q. Can you wear merino wool socks every day?
Icebreaker designs both of its picks here for everyday wear. A r/malefashionadvice poster wears merino socks for several days on trips before they start to smell, while another finds his Darn Tough socks smell by the end of the day; odour resistance is a maker claim, and results vary.
Q. How do you wash merino wool socks?
Follow the label. Icebreaker says “Machine wash cold gentle cycle” and “Dry flat”; Smartwool says machine wash on a gentle cycle in warm or cool water and tumble dry low; Farm to Feet suggests cold water and line drying or tumble drying with no heat.
