Compression stockings are medical grade devices designed to move blood flow. 

Support compression stockings are made available in multiple compression support levels. Most commonly compression support stockings come in mild (8-15 mmHg), Medium (15-20 mmHg), Firm (20-30 mmHg), X-Firm (30-40 mmHg) gradient compression levels.

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.

how do i translate S2 into the questions on sizing to reorder? ankle size? calf size? short or long? I am small boned, normal calf, 5'7" female Asked by Carol

S2 = Small Average Long

when did the price jump to six figures? I can remember paying $65, annoyed when it went to $85, now it's $119? somehow even 20% off an inflated price doesn't impress. Asked by Carol

We hear you. This is one of our favorite products, and the price has become unbearable for many of our customers. Sigvaris has raised the price of the 500 series for the past 10 years straight. We are very sorry, but they set the price. These are made...

what is the difference between the 863c series and the 503c in the 30-40mmhg Asked by Fran

The 863C is made of nylon and spandex, while the 503C is made of natural rubber. The 503C is also made in a wider width and size range. The compression is still 30–40 mmHg.

503CM2O77. This is my prior order for Sigvaris. I can't figure out how to replicate this on your order form. I don't know ankle, calf or length dimensions. I merely want to reorder what I have been using for 20 years. Asked by Richard

Please choose Medium Average Long.

    I buy these sometimes for my friend on a limited income. She has worn them for years. They are great just a little too expensive for her to replace as often as necessary.

    Good but so expensive! 1 people found this helpful


    I have purchased these for about 15 years. I have CVI. Last year I chose the 860C because they were less expensive and bought multiple pairs. Bad decision. I struggled to put a pair on and then it was hell to get them off. So I am stuck, because I actually live in the Caribbean, and cannot return them and cannot use them. I am reverting to the rubber ones but would love a real discount.
