What are compression stockings?

Compression stockings are socks that apply pressure to your legs in a very specific way to enhance the flow of blood.  Compression is greatest at the ankle, and gradually decreases in strength as the stocking goes up the leg.  This is called “graduated” compression and it is essential for medical efficacy.  By squeezing your legs in this graduated manner, compression stockings help the valves in your veins open and close properly.   This is essential to healthy circulation and enables your body to pump blood, against gravity, back up the leg and to your heart.

The amount or strength of compression is measured in millimeters of mercury (mmHg).  Think how mercury is used in a thermometer.  The mercury expands in precise relationship to your body’s temperature.  While measuring the pressure of stockings is slightly different, the principle is the same.

A 20-30mmHg compression stocking has 20-30mmHg of compression at the ankle, and it gradually decreases toward the top of the stocking.  Other standard levels of compression are 8-15mmHg, 15-20mmHg, 30-40mmHg and 40-50mmHg.  The higher the numbers, the greater the compression.  Most compression stockings do not have compression in the foot.

Graduated compression hosiery is considered a medical device and as such requires precision manufacturing and testing. These are images of three different pieces of testing equipment used by the company that makes our Allegro brand of compression hosiery.  The HATRA (left), MST Professional (center), and  NAHM (right).

HATRA, NAHM, and MST testing devices Compression hosiery manufacturers use these machines to constantly test their products to ensure that the stockings you purchase have specific compression at various points in the stocking, with the correct levels of graduation.  Compression therapy was invented in Europe in the last century.  The quality of the end product depends greatly on the quality of the knitting machine and the fibers being used.  The best American manufacturers use the same machinery and techniques that have been the standard in Europe.  We are very fortunate in the US because the manufacturing of compression stockings has, for the most part, not been outsourced.  There are some Asian and South American products on the market, some of which are good, but much of which falls short of US and European standards.  Recently we have seen some inexpensive Asian imports with “reverse” compression, tighter at the top and looser at the ankle.  This will restrict circulation and potentially do more harm than good.

Can you take a little ribbing?

We write all of our sock descriptions and, I’ve got to tell you, after describing our 1,000th sock, words begin to fail us.  But seriously…You’ve probably come across the term “ribbing” in a sock description. Ribbing in socks is very typical, especially men’s socks.  It is the vertical stripe that runs up the leg.  Ribbing is used in non-compression socks to help keep them up.   Since compression hosiery stays up by gripping the leg, the ribbing is more decorative.  It also makes a compression stocking look like a regular sock.  Without ribbing, compression socks would have a flat, smooth finish.  Traditional ribbing is “1X1”, which is narrow and compact.  A recent trend in both regular and compression stocking manufacturing has been to offer a wider, and more contempoary “2X1” ribbing.

Here is an example of ribbing.  On the left is the Allegro Men’s #102 with traditional ribbing and on the right the Allegro Jazz #121, with a more modern, casual look.  On the new Allegro Jazz #121, every fourth rib is accentuated to attract the eye. It’s a small detail but it looks nice and certainly makes it easier to pair socks with the correct mate when they come out of the dryer.  (Did we say dryer?  Most ribbed socks are dryer-friendly, but please check the laundry instructions first!)

Jobst Casual for Men and Medi for Men both offer contemporary wider ribbing.  If you’re a traditionalist and prefer the look of a classic men’s dress sock, check-out Jobst for Men and Medi Patriot.  Both feature traditional 1X1 ribbing.
