The benefits of Compression Therapy are plentiful and the reasons vary from person to person why you may choose to wear compression socks or stockings. As shown in the above chart, some of the most prevalent symptoms or conditions that benefit from compression therapy are:

  • Pregnancy related swelling and vein problems
  • Varicose or spider veins
  • Lymphedema or edema
  • Swelling, pain or blood clots in the lower legs, also known as DVT (Deep Vein Thrombosis)
  • Poor circulation from sitting for long periods
  • Post-surgical and post-sclerotherapy treatment

It can even be used as a preventive measure to maintain healthy legs for someone who spends extensive amounts of time on their feet. Quite simply, when we stand still for long periods, the forces of gravity increase the pressure within the veins of the legs where the greater effects happen at the ankle and decreases gradually up the leg and body. This pressure depends on the vertical distance of the column of blood from the heart to the foot. That's why gradient compression stockings are designed with the pressure greatest at the ankle and diminishing as it moves up the leg in order to counter the effects of the higher venous pressures.

Compression therapy products are put on in the morning upon arising, which is typically before any significant swelling would occur, and then removed at night. Throughout the day the compression prevents blood from pooling in leg veins, which in turn helps your overall circulation and lessens or eliminates any leg swelling you may have.

When shopping for compression socks or stockings, it is best to measure earlier in the day before swelling builds in the legs. Measurements taken later in the day after swelling occurs may cause you to choose an item that is too large and then not effective.

There are many types of compression socks and stockings available without a prescription and they do offer wide-ranging benefits. Before wearing a compression therapy of 20 mmHg (Firm Compression) and above, it is generally recommended to consult your health care provider to find out if graduated compression stockings are right for you. If the answer is yes, they can tell you what pressure grade you should buy for maximum benefit and relief.

    Good alternative to my heavy duty stockings. 0 people found this helpful


    Nice lightweight stocking for when you don't need to wear the heavy duty stockings. Just what I needed. Very comfortable and true to size. Fits well on a narrow foot in S/M.

    Better made 0 people found this helpful


    These do the job--all day. I switched from other brands/patterns that seemed to lose much of the support after one season. Worth the extra $$.

    Great Fit and Easy On and Off 0 people found this helpful


    This is my go to sock. I probably have 8 pairs in multiple colors currently. The silky texture makes them easy to put on or take off. The compression holds up quite a long time but I do use cold water, the gentle cycle and line dry.

    I have found them a little too warm for summer wear but Sigvaris does have a lighter summer cotton blend. They are perfect for office wear.

    Love 'em! 0 people found this helpful


    I bought Sigvaris on recommendation of my physical therapist after she properly measured my legs. These have been the best stockings I've worn in 4 yrs. of trying on my own to find a proper fit.

    Open Toe Excellent. Closed Toe version toe box way too small 0 people found this helpful


    I started wearing compression socks a year ago at the suggestion of a doctor to help control pain. I have tumors that run from my foot up to my knee. They are very painful in addition to limiting function. I've been happily surprised at how well compression socks make a huge positive difference in my pain management. Since I live in South Florida and am often in sandals I usually use the open toe version of this compression sock. I've tried several brands and the only one which I Read morelike is Sigvaris. The open toe model is very comfortable. I wash them on the delicate setting in the washing machine and let them hang dry. They are lasting very long and maintaining their shape.
    I just tried the closed toe version and am very disappointed. The toe box is way too small and the seam very uncomfortable to walk in. I'm going to have to return the closed toe versions.
    The open toe compression socks are wonderfully comfortable and I would highly recommend them.
