I'll admit I'm a Smartwool addict, and don't mind paying extra$$ for their socks, as I've found them to be much more comfortable and durable than other brands. These compression socks fit perfectly and are spectacular for long days in military boots; just spent a 22 hour day on my feet, and I never... Read More

    I was looking for a mid-calf sock but these socks go to my knees other than that I love all my SamrWool socks
  • Disappointed

    These socks have a huge seam near the toes making them impossible to wear comfortably with any shoes or even loose slippers. There are many recovery socks out there without such poorly positioned seams. I love SmartWool socks so was pretty disappointed when I received them. I plan to return them.

    This was the first time that I bought a 2nds product from Sierra Trading Post that was definitely a 2nd. The one sock at the top was stretched out compared to the other one.
  • Nice!

    I will just start by saying that I love SmartWool socks in general. They are warmer, last longer, and stay up better than Icebreakers, Thorlos, or any other technical socks out there. We have used them for 10 years on every member of the family and for many different sports. I also use the compression socks for traveling by car and airplane, as well as for recovery from soreness in my calves due to over use in skiing, biking, training, etc. One thing I feel very strongly about is that you must size up at least one size with all SmartWool socks to counteract the shrinking that happens with the first wash. After that the product is actually a little thicker so it is warmer and lasts longer due to the increased density but still retains a good amount of stretch. I you do not size up I feel that the socks are overstretched on the heels and toes and wear out faster. Also we are all tall in this family so socks that can go up to the knees and stay there in the Polar Vortex Midwest is a plus. I wash these in the machine on warm with regular detergent and dry them in the dryer on a regular setting and they look like new for several seasons. They stay odor free and do not itch. I have a 13" calf, long shins, and a large fit my women's size 9 foot very well. A friend got me a gift of a size medium in these, which would be my correct size, and they were way too tight. Size up and you will be very happy. These were marked irregular but the only thing that was irregular was the smallish sizing. Great socks!

    I like the smart wool compression socks, helps with swelling in my ankle and is warm in the cooler seasons.
    I like the ultra light the best.

  • “What is the difference between these and Item #6685V? thanks.”
    Asked by sooz from florida on 5/20/2014 11:21:28 AM
    • This item is the lightweight, the 6685V is the Ultralight
      Answered on 5/20/2014 4:41:45 PM by Product Specialist Greg from Company Headquarters
    • I do not know anything about item #6685V.

      The SmartWool PhD Graduated Compression Socks are snug but not too tight. I own other compression socks, these are my favorite so far. Since they are made of merino wool, they can be worn for more than 1 day because they are odor free.

  • “What calf sizes do each of the sizes fit? I find my calf size usually doesn't correspond to the same size in shoe size.”
    Asked by taitai12 from Nevada on 5/3/2014 10:20:08 AM
    • I wear an size 11 shoe and my calf measures 16" around. They are snug enough to stay up on 10-15 mile runs, but they are probably designed for a slightly larger leg than mine. Hope that helps.
