    Love every minute of having these on.

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL

    They are the most comfortable and well-made socks I've ever owned! Have used them on some fairly long hikes, and even when wet after stream crossings I got no funk smell. The mesh part is sufficiently breathable and cool. Simply amazed by this product. Once they ended up being a multi-day thing on accident, and still performed great!

    Never leave home without them

      Cotton socks for running is so yesterday...I have replaced my entire workout sock line with these. Slightly expensive, yes, but these breathe so good and they are so comfy that in the long run, these pay huge dividends. Bonus: I use these for everyday gym workouts, 5k runs, hiking, cycling, and yes, even skiing! That is bang-for-the-buck! My feet are prone to sweating more than average, and these have proven to work well at minimizing sweat and funk. Shoe size is 9.5, and the L fits like a glove. Minor quibble: given the ultra light weight, hence thinness, they wear out slightly faster than what I am used to...but still worth the trade off in comfort & heat compatibility.

      Can't Get Enough of 'Em!

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: L

      First off, the only reason that I give them four stars instead of five is that for the price I wish they lasted a little longer.

      That said, these socks are AMAZING. Warm yet breathable, supportive, comfy and if you're backpacking and can't wash them all the time, they don't start to smell quickly at all.

      I love the compression band around the middle - I have super high arches and the support feels awesome. Nice and cushioned where they should be, but not so much that your feet feel stuffy.

      It's great that they come in sizes because I'm always at the far end of the "fits size 4-10!" spectrum. I wear a size 10 shoe and the large usually fits perfect.

      I do find that they wear a little quickly, but I love them so much that it won't deter me from buying them over and over... I just get them when they're on sale so it's not such an investment. I'd like to get enough pairs that I never have to wear anything else again!

      Short lived, thin, breathable sock

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Large

      Great sock that is super thin and contoured to my foot well. Would have loved these socks, but they began to pill and degrade after about a month of light use, washing and hang drying. For reference, I have a 10.5 shoe size.

      The best for 3 season hiking/backpacking

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Medium

      I sweat a lot when I hike compared to most people who I have hiked with, and I've hiked with a lot of people (over 100 in total). I just can't wear the more rugged socks that go over the ankle when I'm hiking in warm and hot weather, like I've seen some others do. These keep my feet cool, breathe well, and still fit my boot well without making it feel like its too roomy. They're also perfect for when I work out on the StairMaster at my gym. I own 4 pairs of these and they don't stink immediately, so it's fine to use them a few days in a row. Another quality smart wool product- the best!

      Durability straight up sucks

      • Familiarity: I've used it several times
      • Fit: True to size

      After wearing a pair twice (once in dress shoes all day, and once in cleats playing ultimate frisbee for a couple of hours) there's already a hole in the toe area big enough to fit my pinky through. I keep my toenails deathly short to avoid holes in my socks and I couldn't believe what I saw when I went to put them on a third time. The toebox on these are WAYYY too thin. If all you plan to do is walk in them they might last a bit longer.



      If it weren't for the thin toebox these would have been the perfect socks. They fit like a glove and don't slide down.

      Perfect uniform work sock

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I am a firefighter and wear these with my uniform shoes summer and winter. They have never failed me. I get about one year to one and a half of use before I need to replace them.

      Happy Feet

      • Familiarity: I've used it several times
      • Fit: True to size

      I tried out a pair of these for summer hiking, and absolutely love them. They cling to my feet without restricting, and stay in place up and down the hills.



      I liked the first pair so much I picked up two more pairs while Backcountry still had them at a great price.

      Classic Smart Wool

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      These socks are great. I wear them all the time. Keep my feet dry and comfortable through a number of different activities. They have stood up through many washes and even the dryer on medium heat. I plan on buying more.

      Lightweight & low profile - also awesome

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I love Smartwool socks. Durable, provide great performance, and look great too. I always find myself at this place when the seasons are transitioning from snow to sun where I have no appropriate apparel for my feet. You know, it's the time when it's too warm for your big winter socks but not quite warm enough to bust out the Chaco's. Because of my track record with Smartwool and the vast amounts of pleasure I receive from wearing them, I grabbed a couple pairs of these and put them on. It's been a great couple of weeks as my feet have gotten to know these socks very intimately. The construction on these socks are very low profile so no bulky heel or toe, but just enough padding to keep your dogs from barking at the end of the day. I'm going to be sad when this spring weather lets up and I have to say goodbye to these socks for a while so my feet can experience the freedom only a flip-flop can provide.

      Cotton-no-more

      • Familiarity: I've put it through the wringer
      • Fit: Runs large

      These are the first socks I've bought in 5 years. My last smartwool's lasted that long. Kind of unbelievable looking back. I haven't owned cotton socks in 10 years--yuck!



      Everyone thinks I'm a bit weird when I prostletize them about the merits of fitted, merino wool socks, and at $10+/pair, I can understand people's initial worry. But only the uninitiated. Every single person I have ever bought these for as gifts, ended up going on and buying several more for themselves.



      If you haven't worn smartwool socks before, you can only understand once you put them on. They're very snug and fitted, without cutting off any circulation or anything. They don't shift around at all on your feet when you spend an entire day hiking, and keep you much cooler and dryer than cotton.



      I'm a size 8.5US street shoe, and buy the S/M size--they're perfect. Just make sure to hang dry them people--no dryers or fabric softeners!



      These will be my first pair of SW's since they came out with this "PHD" line, but so far I have no reason to think that they'll be any different than my last 10 pairs.

      Sock it to me baby!

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      SmartWool PhD Outdoor Ultralight Mini Sock is the sock of choice for my spring and summer outdoor activitidads... From hiking to trail runs, to strollin down the block headed to the b-ball court in a wrapped in a sick pair of Reebok Pumps, for a pickup game. Bottom line? Keeps the dogs dry and smellin good, blister free, and comfey!

      Favorite socks

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      These are the best socks I've put on my feet. Super comfortable, lightweight enough for day to day and not get too hot, durable, and they keep your feet dry! I won't go back to cotton again, and even synthetics seem far inferior after using these for a while. I got the Espresso color on sale, which is pretty ugly, but whatever, they aren't white and they aren't visible. I wear them with jeans most of the time anyways, or running, so not a big deal. Overall, fantastic socks, will be buying more, especially when they go on sale

      Happy Feet, Yo

      • Familiarity: I've put it through the wringer

      These socks are great. They make me feet feel happy, and I smile to myself as I run through my neighborhood. People think I'm smiling at them, but they just don't realize I'm smiling because of these little bags of ecstasy that cling to my feet. Get some.
