Improve Blood Flow
Veins carry blood back to the heart. Your legs contain a network of veins. There are two systems of veins in your legs: The Deep system, that is within the muscle compartment of your legs, and the Superficial System. The Deep System does the heavy lifting with return of blood to your heart, because the muscles act as a pump to move the blood back up to your heart. Superficial veins (near the surface of the skin) connect to perforating veins that connect to the deep veins.
