The concept of compression therapy is based on a simple and effective mechanical principle: the use of an elastic “garment” for the leg.
By compressing the limb with a graduated pressure, maximum at the ankle and decreasing as it rises up the leg, the compression stocking promotes venous return, reduces venous pressure, prevents venous stasis and deterioration of the venous walls and provides effective relief aching and heavy legs helping the body to draw blood up the leg against the force of gravity.
