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.

    Jobst Sport knee-high compression socks are great!!! 0 people found this helpful


    I have been wearing knee-high compression socks for about 15 or 18 years to prevent swollen ankles and calves. About 6 years ago I tried the Jobst Sport Sock Knee High 20-30 Closed Toe socks and I liked them so much that I bought several pairs and now they are the only compression socks I wear. Like the person who wrote the "Forest Photographer" I frequently walk around in fields and forests and national wildlife refuges taking photos of flowers, bugs, birds of all sizes and whatever type of wild animals I come across. These Jobst sport socks are very comfortable even when walking around for most of a day. And the socks do a great job of preventing swelling in my ankles and calves. Plus, as another reviewer mentioned, the Jobst Sport knee-high compression socks look good when wearing short pants.

    Very comfortable & great support 0 people found this helpful


    I have been wearing other styles of Jobst compression knee-high socks for six or eight years. About a year ago I tried a pair of the Jobst Sport Socks and I liked them much I bought several more. I have been pleased with all of the Jobst compression socks, but the sport socks are extra special because they are more comfortable than the other socks. The extra comfort is especially noticeable in the part of the sock that is inside the shoe. The extra thickness and softness of the sock material provide a comfortable cushion for the foot. These sport socks are especially great for field trips when I spend several hours at a time walking through fields and forests. And they are also very comfortable for when I go to the gym for exercise classes.

    The best Jobst ever 0 people found this helpful


    I've been wearing Jobst compressions socks since 2001. I've had numerous knee operations, including total knee replacement. I’ve experienced lower leg swelling since these procedures. I gave these a try because I suspected they would be cooler during the hot weather months. I was not disappointed. They're very cool and comfortable during the hot weather and provide the level of compression and support I require. Because they're so soft, they're also easy to put one and stay up during all day wear. As an added plus, they appear very stylish when wearing them with shorts. Of all they styles I've used and tried, these are by far the best ever for me. I now intend on using these year round.
