Good liner or dress sock

It makes a good liner sock. It wicks moisture away; keeping my feet dry all day inside my combat boots. It also makes a good dress sock.

excellent boot liner
December 28, 2012

Purchased for my wife, who loves boots but hates most socks under them. She says these are perfect: they are thin, they are warm, and they wick effectively. Too early to tell about longevity, but other Smartwool socks have lasted well.

Pros: Build quality, Performance

Not as good as expected
November 30, 2009

These socks are not as soft and thin as I had expected from reading the reviews. The material feels cheap. I would not recommend it.

Excellent socks. They are comfortable and appear to be durable (I think they’ll last a long time). I've worn them for 2 weeks straight and they don't smell. Highly recommend.

Good Liner
January 20, 2011

This liner fits well and is very comfortable. It has held up well so far, but does not seem to be as rigid as I would like. They do provide a good buffer zone for the foot. I have not used them on any intense hikes, but they performed well just walking through the woods.

Pros: Performance

Nice liners
April 07, 2007

Nice liners to wear under my wool socks. So far so good. No blisters!

Hiking
August 02, 2008

always end up with blisters so i bought these to wear under my hiking socks and so far so good. no more blisters. only downside i've noticed is that when your feet sweat the black dye will stain your feet.

Great Sock

Excellent wool liner
January 16, 2011

This liner is a little thicker than synthetic (polypropylene and Coolmax) liners, but it is an excellent choice for cooler conditions and if your boot/shoe can accommodate the additional layer. I've worn these cycling under merino wool socks, and I've worn these hiking under the Smartwool mountaineering socks. These liners did a great job of wicking away moisture and keeping my feet warm. I wear a size large in all Smartwool socks for my size 12 feet, and the size large for this liner fit just right, as expected. An additional bonus over synthetic liners is that putting on socks over these liners seems to be easier than with synthetic liners; the outer sock glides over these liners easier. I've read of others wearing these as dress socks, and I can see that the black liner would be a perfect choice with black dress shoes. The liners are suffliciently thick and have good elasticity to serve as a good dress sock. They don't slip down as synthetic liners would.

Pros: Build quality, Performance, Ease of use

Great for Winter Hiking... or Anytime
December 06, 2007

These are excellent liner socks! Currently, I use them mainly during cold weather, since they provide a significant amount of warmth yet are still very thin. If your feet get cold easily, I would definitely recommend using these liners. And even if your feet don't get cold easily, I would STILL recommend using these liners, since they are super soft, comfortable, minimize sweat and are a natural fiber!

March 27, 2010

Smartwool comes thru again. Love their socks!!!!

Good value
May 13, 2009

Not a bad sock for the price. Good as a thin, stand alone or as a liner. Very comfortable. Haven't owned them long enough to say how durable they are. I wear an 11 & they fit me a little loose; I think smaller feet would swim in the size large.

Awesome
January 04, 2009

I use these socks mainly on their own when I want a thin breathable sock, and I wear them instead of icky nylon "trouser socks" with my work shoes. I initially bought them to wear with some Dansko clogs that are tight-fitting. I only had one pair and I just bought three more, I love them. I can't wear wool usually, but Smartwool socks never itch.

great sock liner
November 09, 2012

I absolutely love all of my previous pairs of smartwool socks. Have been through quite a few pairs of their old uniform socks, and have been quite impressed with how well they have held up to daily use for work. Thought i would try and use a their sock liner to help me break in some new hiking boots, and they really increase the overall comfort (even for well broken in boots) no matter what the activity that you are doing. Highly recommend wearing liners under your smart wool socks.

Pros: Great design, Build quality, Ease of use, Great value

keep those tootsies happy
December 10, 2010

Having tried liners of various fabrics to wear under my hiking socks, the Smartwool wool hiking sock liners are prresently my winter favorite. After having tried other fabrics, I find the fit is good, with no bunching while hiking over various types of terrain - and perspiration exits fairly well. The socks dry fast enough for me. The quality for the money is okay, but one other very comparable content merino wool liner that I recently tried rates overall the same to me - and they retail for about $3 less.

Pros: Great design, Build quality, Performance, Ease of use, Great value, Cons: Cost

answer to foot prayers
March 15, 2010

These may be the best everyday socks ever. I'm tall and female, which means socks are about impossible to find (women's socks are too small; men's are too big). I'm also big on comfort. These liners socks are perfect. They're comfy. They fit. They're not bulky. My feet are happy. Again, I bought them to use as everyday socks (I wear clogs), not as hiking boot liners.

Ready to Go!
August 12, 2009

These do what a good liner sock should do and live up to the Smartwool name. They are slightly heavier than some, so allow room when buying shoes.

Excellent

small is too large...
March 28, 2011

I'm a great fan of smartwool, especially of their PhD socks. Sock liners in general are a great idea and I have used these ones on several hikes this winter as well as for skiing. However, the S fits still too large. I am a 7, European 37 - hence my feet are not supersmall. Nevertheless, the sock liners are slightly too big to fit snug as they should. As for durability they seem fine after some miles and washing but I also don't expect them to last as long as the expensive PhD socks. Overall, a solid product, just wished the sizing was better.

February 23, 2011

I have used these Smartwool liners over the years, and have always been pleased. They add comfort when hiking under all conditions, and add surprising warmth during winter wanderings. They add very little bulk, and dry quickly. I am very pleased with these liner, and recommend them highly.

smartwool liner sock
January 03, 2011

It's cold here, and I am even pretty much an indoor person. However, I have been known to wear my liner smartwool socks all of the time for a week. Luckily, my foot in them produces no odor - I attribute that to the socks. Also, they keep their shape the whole time. They are light weight, and yet still much warmer than a regular sock, or a big heavy sock. They are totally smooth and not itchy. The amount of choices for the smartwool at ordering was some what overwhelming, but I overcame that by ordering black for my first pair...a no-brainer so to speak. I most certainly will be buying more.

Nice socks - Typical of Smarwool
July 16, 2009

These are nice liners. Don't think these are thick, but in the past I'm used to really really thin liners that are almost like second skin and are really slippery. That said, they're still pretty thin and slippery enough between sock layers so from my observation and experience using them during backpacking/hunting they do the job well. They fit snug, as a liner should. FYI, I always err on the smaller side because you do not want your socks to bunch inside the boot (especially a liner). That said, with most liners, if they're too small, they'll stretch way out and the threads will have more surface area with space between the stretched threads. If that's the case, the liners will stick to your feet/outer socks defeating (no pun intended) the purpose of the liner. My two cents. Anyway, nice sock as expected by smartwool. I'm paired with the PhD medium cushion Outdoor socks and it's the best combo I've used for hardcore packing while under decent load (60-80 lbs). Get differnt colors so you know which ones in your pack are 3 day old funk. Enjoy.

Tried two brands
April 04, 2011

I ordered and tried this brand and the Bridgedale sock liner. I preferred the Bridgedale sock liners with the Smartwool heavy crew hiking socks. It seemed that the the Bridgedale liners had less hot spots than the Smartwool liners.

Good Liner
April 06, 2010

Wore these as a liner under my hiking socks for backpacking. No blisters, rubs or hot spots. I bought a size M based on a women's shoe size 8. The fit is not as snug as I would like for a liner. Next time I would buy a size S.

wonderful sock!
December 17, 2009

I actually bought these socks for snowboarding, not hiking. I was wearing them under my smartwool warm socks. I loved the combo. I stayed perfectly warm in sub-zero weather and didn't feel like I sweat a drop. I wore a different pare of liners then next day, and did not have the same results. Very comfortable!!!! I would highly recommend these liners.... at least for snowboarders!!

Smartwool liners are the best
January 04, 2013

My husband wears liners and wool socks every day to work. He has tried several brands of liners, and finds that Smartwool makes the absolute best. He's a size 10 and finds that they fit just right. He says the socks keep his feet dry and warm all day. Better still, they last like crazy. I bought him some Smartwool liners three years ago (and each pair was worn at least once a week) and they are still in excellent shape. Other liners didn't fare so well -- the elastic stretched out so the socks slide down too much and get bunched up in his shoes. The Smartwool liners, on the other hand, keep their shape and the elastic is as good as it was when I bought them. The only reason I bought more is that I didn't want to have to do laundry enough to keep the three pairs of liners that he loves clean! Now he's got 6 pairs, and he's a happy camper. An excellent liner that will last and last.

Pros: Build quality, Lasts forever, Performance

Pretty Good
April 10, 2010

Good sock by itself. I am in Afghanistan and these kept my feet dry and comfortable, even in the summer months. I could not use as a liner due to boots not being sized for liner/sock combo. No bunching even after miles of rucking.

warmth and comfort
August 20, 2012

I bought these for a Kilimanjaro climb - comfortable (no blisters or abrasions) and warm yet thin enough not to create too much bulk when wearing two pairs of sox. I rated "good" for durability only because I have not owned this for very long.

Well worth the money, very comfortable next to my feet.

love 'em
July 07, 2010

Much prefer the still thin yet more cushioned & breathable feel of these liners over the synthetics I've used in the past. Enjoyed a brisk paced 7 mile hike in 70 plus degrees yet felt completely comfortable temperature-wise & no blisters - since ordered more -

I haven't had them long enough to see how they'll hold up, but if they're anything like my other Smartwool products I'm sure the quality is excellent. They do run a little big. I normally wear an 8 1/2 or 9 Women's shoe so I originally tried the medium liner sock. It was a little big, so I ended up with the small liner. Since you're wearing another sock over it, the liner should fit really well, so you might need to order a size down.

great all-purpose sock liner
October 25, 2012

I use these liners for backpacking, cross-country skiing and snowshoeing. They are thin enough to wear with a regular weight hiking sock, fit great (no slipping) and dry pretty quickly. The black color is great since it doesn't show dirt. The wool keeps odor to a minimum. They do a great job at preventing blisters. My only gripe is that they don't wear as long as I would like for the price.

Foot Heavan
August 05, 2011

I bought these socks to line under a pair of Bridgedale socks and standard offshore work boot. When wearing just the bridgedale socks my feet still got cold towards the end of my shift due to the moisture build up. Once I used the Smart Wool liners what a change! I just finished two months on a boat in the North Sea near Norway and not one day did my feet feel cold, tired, or generally in poor condition. I am usually on my feet most of the day and stand often on cold decks. The socks really do what I wanted them to do. I had been a little disappointed with Bridgedales alone. I cannot imagine now going offshore to work without at least four pairs of these socks. They made my whole two months work so much better. A great product.

Pros: Great design, Build quality, Performance, Ease of use, Great value, moisture control

Great lightweight sock. You can use it as a thin sock or a liner if you need more protection from cold or blisters. It does feel a tiny bit scratchy, but that is good when it's warm. Fit true to size.

High Comfort
November 26, 2012

Had two pairs of these liner socks with me for a 7-day trip in Grand Canyon N.P. No blisters and no cold feet for the first time. I wore them in combination with the S.W. hiking socks and high quality hiking boots. However without liner socks, I had always blisters and problems with my boots. The socks dry very quickly and they were sufficient for nights in the sleeping-bag. No signs of damage or usage up to now. However as they are very thin, I do not think that they'll last forever. Therefore Durability: Good
