    Comfortable, great exercising socks!

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

    I've used these for running, biking & walking. Great quality of socks that dry quickly & are comfortable. They are a tad thicker than the socks I've previously worn but as long as you don't have very snug shoes, I highly recommend these.

    These are becoming my new favorite sock. I decided to put these through the 48-hour test. 16 hours of warehouse work 2 workouts so you can say a gave them a run for their money. There was no noticeable odor, my wife's nose is pretty keen on smell and she lets me know about it. after that much time in a cotton sock, it would have become floppy losing their elasticity. even after the second gym session they felt just as supportive. I've washed these several times and still like new. Perfect sock for hiking or backpacking.

    So far these socks have performed very well. No blisters even when sopping wet. I paired these with Merrell yakotas, wore them to work for ten hour days, wore them on trail packed snow multiple times and on hard surfaces. Everything about this sock is what I wanted in it and performed like it should. I wear a 9-9.5 and bought the larges, bought three pairs. Recommended

    These are definitely my favorite socks. Great for running and hiking or just everyday use, which is what I use them for the most. If you're looking for a low cut do everything sock, look no further than these.

    Great for hikes or running

    These are great for a variety of activities. While they certainly keep your toes toasty in colder temps, I don't typically have an issue when the thermometer runs into the 80s. My feet don't sweat much, I guess, and the natural merino fiber keeps the sweat that does happen in check. Definitely recommend anything in Smartwool's PhD series. I got the mediums which are on the small end of the spectrum for shoe size 9-10 but they fit well.

    Solid sock - maybe a bit too solid

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

    So I really like this sock. It's comfortable and has some good cushion. But I find that most days I'm going jogging my sub-conscious is looking for other socks first. I think it's because the sock is a little too thick. Might be better for the day hike than the morning jog.

    EXCELLENT!

    These socks are great and worth every penny! Super comfortable and supportive. Even after days of hiking in them they hold their shape and don't stretch out into a floppy mess. I highly recommend picking up a pair.

    Best Sock Out There!

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

    There is not a better low profile sock out there in my opinion. If you like to wear socks that barely show with your tennis shoes then you need to buy these.
    Smartwool did a great job addressing the huge problem that small socks have, sliding off your feet and bunching up in your shoe. Smartwool has conquered this problem with Magic. You can put these socks on and never worry about them falling off. Super comfy and soft. I will be buying several more pairs.

    Favorite sock on the market

    I own about dozen pairs of these socks. They've held up remarkably well. From every day wear to running, biking, and even trail hiking these socks keep my feet in good shape.

    Light, good wool. Juuust right. I bought 2 pairs and will probably buy a few more now that I've tried them.

    Smartwool phD Outdoor Light Micro Socks

    These are the favorite socks at my house. They are soft, durable, and have just the right amount of cushioning. They are great for running, trail running, hiking w/low shoes, casually...whatever you need them to do, they're up for it.

    Mmmm...toasty

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

    These socks are the bomb! The slight compression of the socks wraps your foot up and keeps the socks from slipping around and they are just great at keeping my feet at a comfortable temperature. Slowly trying to have nothing but SmartWool in my sock drawer for the superior quality.

    Love these socks!

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

    These socks feel great! Perfect for running, hiking, or everyday use. I never thought socks could offer "support" but the compression design really helps. These offer much more support than the old cotton socks I have been wearing for years. I would definitely purchase these again.

    By the beard of Zeus, these socks rock. I am obsessed. They are probably the most comfortable thing I have worn on my feet...ever. They off awesome support and help keep your feet dry when you are running around and playing in the snow.



    I have about 9 or 10 pairs and they are my go to socks.
