I've been a SmartWool fan for years - a high quality product and STP's unbeatable prices. When I saw these compression socks, I had to

give them a try. I have lymphedema in my lower left leg and I'm on my feet all day at work. When I took these socks off this evening, there was absolutely

    These compression socks are surprisingly comfortable. At first I was concerned they would be too tight. I wear a size 12 jean, I'm 5'5" and weigh about 150 so I'm not skinny but not obese. This middle size makes it difficult to size these sorts of items. These socks are firm, definitely provide good compression but are not too tight, no cutting off circulation. Feet also do not overheat your feet as the wool is very breathable. Highly recommend. Great for after running soreness or travel.

    Love them, on my feet all day and help with swelling

    I have very thin legs, but this sock fit really tight. That was okay until I developed severe cramping from all areas of my legs above the tops of the socks. I could not get them off and my husband had difficulty doing so. The cramps persisted for over an hour. I cannot imagine who could wear the small in these, because I have about the smallest calves of anyone I have ever seen.

    these socks seems to be a little short in length otherwise they are very nice

    I have only skied in SmartWool socks for at least five years. The compression really helped keep me on the snow longer. I wish I'd bought more before the size I need ran out!

  • Question “What compression strength are these?”

    Asked on 2/4/2015 4:19:02 PM by Marian from Nola
    • Answer I have no idea whether there is some objective scale of compression, but it would seem that would depend on the size of your leg. I wear a size 7.5-8 women's shoe, or 6 men's, but my calves are pretty large. I got the small. They are tight, but comfortable.
      Answered on 2/4/2015 4:22:56 PM by Becky from Wisconsin
    • Answer I believe they're 20-30 mmHg but you can double check that on the SmartWool website.
      Answered on 2/4/2015 4:41:40 PM by Nicknameless from Washington
    • Answer Not listed but if you can find the exact match on the Smart Wool site you may be able to get your answer. These are very snug for sure, had to size up just to get them on.

    • Answer I'm sorry that I don't know the exact answer. I find them helpful for giving my lower legs a break. I would guess that they are a medium compression.
      Answered on 2/4/2015 4:53:46 PM by Old Biker from AZ
    • Answer These are not graded like prescription or diabetic socks. I would consider them medium compression. I have what I would consider normal legs and these are snug. If you have large ankles then they will be tight.

    • Answer on the packaging I received, it says the compression is 20-30
      Answered on 2/4/2015 8:51:53 PM by dt from ohio
    • Answer My guess is 15-20 mmHg. These were tight on me so they felt comparable to a 20-30mmHg sock. I do not think the are rated that high though.

    • Answer I cannot say with certainty, however, working as a nurse and placing TEDS socks on post-operative patients, and on myself after surgery, these socks feel like a minimum 20mmHg or a little more. Its an effort to put on and remove... Not just great for running/recovery time, but great for long haul transoceanic flights as well which is what I bought them for. Hope this helps.

    • Answer These are "mid-grade compression support"
      There does not seem to be a compression number on the packaging.
      Great socks!

  • Question “Where is the sizing chart for women? I wear a size 9.5 shoe.”

    Asked on 11/3/2014 9:37:14 AM by MB from Ontario
    • Answer I also wear a women's 9.5 shoe. The size Large fits perfectly.
      Answered on 11/3/2014 10:24:58 AM by Margaret from Chicago
    • Answer If you place your cursor on the "small, medium, or large" options/buttons, then a small dialogue box should appear with the proper sizes for both men and women. If you are a 9.5, then a medium would be your best bet...but you are on the edge. The medium 7-9.5 in women's sizing. Different brands run different sizings, you might want to find a brand that includes the 9.5 as not being either the max or min size option.
      Answered on 11/3/2014 11:11:07 AM by Woodsdeepin from Kentucky
    • Answer Not sure. I often find that the sizing charts don't help me. For me as a size 8 shoe with about a 13" calf, the smalls were way too small. I've got two pairs of Large teal colored ones that work well, though at the end of a 10 hour shift, there's a red indentation on the back of my legs. A pair of the black Large compression ones seem a lot smaller, and not wearable for work. Not sure if that's a effect of the "factory seconds" lot. My guess is that the calf size matters more for these than the foot size...

    • Answer I wear 9 1/2 womens too, I bought a Large and I couldn't even get them on.
      Answered on 11/3/2014 12:08:50 PM by grammie in nh from nh
    • Answer My experience with shoes and socks are women's sizes are 1.5 to 2 sizes below a mens (e.g.; women's size 8 will be man's size 6 or 6.5). The same crosses over for socks. I suggest you consider your sock size a women's 10 and look for what would fit a men's 8. I have these socks and they run a titch on the small side, even when being careful to line dry them.... Regardless - love the socks! Have 2 pairs - black and off-white....

    • Answer just put ur cursor on a size s/m/l and it will tell u what size shoe it fits
      Answered on 11/3/2014 7:16:33 PM by john trucker from new york
    • Answer Michelle, I wear a 9.5 shoe, also. I order the medium but alsways stretch the length of the foot when I wash them and never put them in the dryer. I tried the large one time but they are too long and bunch up in the toe of my shoes. Be aware that if you need compression around your ankle, these are not the best socks. If you look closely, you'll see what looks like a narrow ribbing around the ankle. That has less compression than the part above the ankle. This allows my repaired ankle to swell. Product #1940p has even compression, if that is what you need.

    • Answer Hi Michelle,

      I wear a size 8.5 women's shoe but I have large calves so I buy the large compression socks. I guessed and it has worked out well.
