The concept of compression therapy lies on a simple and efficient mechanical principle: the application of an elastic garment around the leg.
By compressing the limb with graduated compression -- strongest at the ankle and decreasing up the leg -- the compression stocking helps venous return, decreases venous pressure, prevents venous stasis, reduces edema and deterioration of venous walls, and efficiently relieves aching and heavy legs by aiding the body in moving blood up the leg.
