Juzo Assist Knee High Open Toe The Juzo Assist delivers comfortable compression therapy with a unique, patent-pending knit that glides easily over feet, effective, and easy to wear. To improve circulation, graduated compression stockings are often part of a management plan. As you move, graduated compression stockings apply pressure to support the calf muscle and outside of veins to help the valves close. The compression starts at the ankle and gradually decreases as it works its way up the leg, helping to improve circulation, manage your discomfort/swelling, and give you more freedom to move.
