Perfect Trail Sock

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

The merino material is right on for long trail runs or short hikes alike, and the cut is low enough to be out of the way yet high enough to not get wedged down in your shoe.

Smartwool is the best!

  • Familiarity: I've used it several times

I don't think I've ever had a negative comment about any Smartwool piece I've owned. Socks are no different. These are light and great for anytime that shoes need to be worn.


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

I am hooked on merino wool socks for my outdoor adventures - hiking, biking, trail running, you name it. These are high quality and have a low cut just below the ankle bone. They are light weight but not ultra light, more towards medium cushion. Fits nicely in my shoes and wearable for hours.

Smartwool never disappoints!

    I've worn Smartwool socks for decades now, and have never been led astray. Comfortable toe seam, great cushioning, cute cuts, practical fit for hiking, extremely durable. These socks will last you for years and years. Highly recommend!

    Gave this as a gift to my mother and I can say with utter confidence that she loves them. She spends a lot of the day on her feet and she rejoiced that these socks did not give her swamp foot. 10/10.

    Snug and cushy

      Just like my other SmartWool socks, the Light Micro ones do not disappoint. They are snug and don't slide around (I HATE that!), rise out of my shoes high enough that there is no heel rubbing, keep my feet cushioned and able to breathe. Love the Hibiscus color! The only thing I would say is that these were slightly thicker than I thought they would be with the name "light micro" - there is definitely some cushion.

      Fits like a Sock

      Got these for my GF she says that they are warm, comfortable, stayed in place. Would be great specifically for running or hiking, but also for an everyday sock. Orange is cute color. Would buy again.

      Amazing Socks!

      I love the color of these socks! I have them in mineral and coral. These breathe very well and wicks the moisture away. These held up after loosing my footing and falling in three feet of water and rapid river. My feet never got cold, they dried quickly, and made the rest of the outing bearable. They piled a bit after the first wash but it did not interfere with the integrity of the socks.
