Compression stockings are used to support the venous and lymphatic systems of the leg. They offer graduated compression where maximum compression is achieved at the ankle and decreases as you move up the leg. This compression, when combined with the muscle pump effect of the calf, aids in circulating blood and lymph fluid through the legs.
Today, compression stockings are available in a wide range of opacities, colors, styles and sizes, making them virtually indistinguishable from regular hosiery or socks.
Compression stockings are offered in different levels of compression. The unit of measure used to classify the pressure of the stockings is mmHg. They are often sold in one of the following pressure ranges:
Support - over-the-counter
With the advice or prescription of a physician or medical professional and proper sizing from a trained fitter.
Compression levels used by some manufacturers for custom made, flat knitted products in the US. Also used in Europe.
