Best socks ever

  • Familiarity: I've put it through the wringer

I have so many pairs of these I've lost count. I wear them everyday, for any activity. Super comfortable, wicks sweat, and never stretch, shrink, or fall apart in the wash or dryer. Don't think I'll ever buy a different brand of socks!

Love em!

  • Familiarity: I've used it several times

These are great socks for any activity! I wear them for hiking, biking, and as an everyday casual sock. The merino wool material wicks moisture quickly and keeps your socks from getting too stinky.

Good for hiking

  • Familiarity: I've used it once or twice and have initial impressions

These are really comfortable for hikes, they are not super warm so you can use them in different weather. As usual Smartwool doesn't disappoint

Winter Socks

  • Familiarity: I've put it through the wringer

Incredibly comfortable socks from smart-wool. These are definitely winter socks and run thicker than a lot of other winter socks. 5/5 would recommend.

Too comfortable?

    No they're not too comfortable, there is a certain limit for comfort that these socks have reached which other socks which they could achieve. I've worn these around the house and on tough hikes, same comfort for both!

    I wear only merino socks.

    • Familiarity: I've put it through the wringer

    I've tried most brands of merino socks out there and keep coming back to Smartwool. They are high quality and I know what to expect.

    High quality feet sweaters

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

    These socks are very well made and look great. I've purchased them as gifts for the family and everyone seems to love them.

    The only winter sock

    • Familiarity: I've put it through the wringer

    The PhD is top notch. I have a few handfuls of Smartwool socks, and the PhD is my go to for those tougher longer days. These wool socks offer comfort in the heel and arch while not overdoing the thickness for full dexterity in the toes. Amazing sock, you should have one (or five) for every adventure!

    Perfect for winter

      These are water-wicking and the medium warmth is just right for a casual winter day. They'll keep your feet warm, but not overdo it. These are extremely comfortable, too!

      Excellent SmartWool product

      • Familiarity: I've put it through the wringer

      These are great boot socks - I have purchased several SmartWool products and they never leave me unhappy. Their materials are top notch and they wear fabulously. Give them a try if you havent already.
      These particular socks are thick and absorbent - definitely a great cool weather boot sock.

            • Familiarity: I've put it through the wringer

            Does any company or product offer more value for the money than Smartwool socks? Can't think of a single one.

            Another excellent Smartwood product!

            • Familiarity: I've used it several times

            I have become a HUGE fan of all Smartwool products. These are a nice thick sock that does well in boots and outdoor uses. Keeps its shape and washes well.

              Smartwool for the win

                Best Sock!

                • Familiarity: I've put it through the wringer

                Take your socks seriously and you will never regret it! I love this midnight sock that is good for most seasons. It provides great cushion and warmth without the bulk. Be good to your feet and snag a pair of these!

                Great Sock

                • Familiarity: I've put it through the wringer

                Great socks for colder weather. Super comfortable and durable.


                  Hubby up'd his sock game for the mountains during the colder season. He is happy for toasty toes and dry feet during his adventuring
