    Great compression socks

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

    Delivers great compression and feels amazing after a run
    Incredibly well constructed.

    I machine wash them and air dry them and they look like new every time.I own these and Zensah compression socks. Compared to the Zensahs, these are a lot tighter in the feet but feel pretty similarly around my calves. I prefer these 2XUs because my feet swell more than my legs.
    I wore these after running my last Ragnar leg and they felt so good!

    Great value but I do wish they came in brighter colors.

    Snug but Just Right

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

    My ski boots are a tight fit and I need the thinnest sock possible. These are the thinnest socks I have found on the market and have the added bonus of minimizing fluid build up in the feet. They are the only way I can get though a full inbounds day without having to take a trip into the lodge to air out my feets. Awesome compression sock. I bought a medium--I have a high volume size nine foot, but a low volume calf/ankle. Fit is great.

    Great for touring

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    I bought these as a gift for my brother, he previously owned a pair and was in need of I bought him 2 pairs! He loves them, they are light enough that his feet don't get sweaty when he's in walk mode while he's touring, compression keeps the blood flowing. Great socks!

    Keeps the toes warm!

    • Size Bought: Large

    My ski boots are very tight fitting so I do not have room for thicker socks on those colder days. I was skeptical about a sock so thin actually keeping my feet warmer, but I have been pleasantly surprised. Compared to the PhD Ski Ultra Light, these socks are much warmer. The compression works to keep my toes warm for a full day of skiing and I have also noticed less fatigue the day after.

    My only concern is that if my calves were any bigger the compression would be uncomfortable. If you have any questions about sizing please contact me directly.

    Great for long flights

    • Fit: True to size

    I bought these for my fiance for a trip to India. He raved about how much they helped his circulation while traveling for over 20 hours. He found them to be really comfy and kept his feet warm on the cold plane.

    The best

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

    Ive never used a compression sock. I have very picky feet so I stepped my foot game up and got footbeds for my ski boots, I decided if I dropped that kinda money on footbeds a good pair of socks was a no-brainer.

    These are amazing. Not only did these help my circulation (ive gotten minor frost bite and have constantly cold toes) but the tightness of the sock virtually eliminates any bunching that can occur while inside the ski boot. Quality is another huge factor. These can be a little bit more of an effort to get on and was worried about ripping a hole in them pulling them on.....not an issue. The build quality is superb and you can tell that these are built to last.

    BUY THEM yuh sissy

    Maybe too tight for skiing?

    • Familiarity: I've used it several times
    • Fit: Runs small

    I bought these with the hopes of riding in them but I think I got them a size too small as they have been cutting into my calves too much. Nonetheless, I have been wearing them after skiing and when travelling and have made a big difference.

    I really like the ultralight weight socks. My feet get cold easily and my ski boots never fit well, and conversely, my feet stay warmer and my boots fit better with the thin wool sock. This year I upgraded to the graduated compression; takes some getting used to but I like them better!

    A great lightweight sock

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

    I have used these socks exclusively for about 3 years. You may ask, why the exclusivity in sock choices? The answer to that is two-fold; I am a picky b*stard when it comes to my feet and they are the best. I have used my oldest pair over 300 days, and they only have one small hole in the heel. What is more incredible though, is that they don't stink like my ski boots. The merino wool does an excellent job fending off my pungent foot stank, and keeping my skin dry. Thin socks are my favorite way to go when skiing, they allow for much better circulation which leads to more warmth. It seems counter-intuitive to say that the thinner the sock the warmer, but in ski boots that is how it works. Blood brings warmth, so letting your blood live wild and free is the way to go. The graduated compression in these socks provides a bit more encouragement for your blood to flow, another bonus for the warmth. Moral of the story; I love them and am pretty confident you will as well. If you're in the market for some new ski socks, this may be your stopping place for a few years, it was for me.

    I'll take ALL of them please

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    Bought these yesterday and wore them today. LOVE them. Used the sizing chart to figure out which socks would work (I'm 6' 1" and play soccer so my calves are a little larger than normal) and the larges fit like a dream. Very warm even though they are light weight and thin. Haven't worn them on the slopes yet but for running and sitting around the house, they have been amazing. Definitely ordering a lot more.

    Favorite Socks

      These are my favorite socks I've had, although I have only had 2 pairs.

      They're the thinnest you can go without sacrificing much if any warmth, so you get a really intimate feel with your boot (seriously - makes a difference).

      The other major upside is the gradual compression, which is GREAT for my swollen ankle that I sprained playing football 8 years back - keeps that garbage in check.

      Also, gotta love that blue!

      Great for the Minimalist

      • Familiarity: I've put it through the wringer

      Great alternative for the most minimalistic fit from Smartwool. The "light" version will provide a touch more insulation than these for colder days, but these do quite well for most days on the slopes. Like most Smartwool socks, they're super comfy, and it's tough to make 'em stink.
