Compression stockings come in different lengths, including below the knee, knee-high, thigh-high, and all the way to the waist, depending on what they’re being used for. Instead of putting the same amount of pressure through their length, the socks apply graduated pressure to keep your blood moving.
This compression helps tiny valves inside the vein function better and promotes the flow of blood back to the heart, preventing excessive pooling of blood in the lower extremities and even reducing the risk of blood clots.
