The job of the veins of the leg is to channel blood back to the heart. Since the legs are generally lower than the heart, this process must occur against gravity. To prevent the blood from simply running down hill and pooling in the feet, the larger veins are equipped with a series of tiny one-way valves. For various reasons, mostly due to genetic weakness, these valves frequently fail to close all the way and allow blood to flow towards the feet instead of the heart.
