The Venenvalker Vitalschuh (vital shoe) is the first shoe with a pneumatic compression of the sole of the foot. It supports and increases the natural compression of the sole of the foot while walking and is a class I medical product. In spite of its special features, the design of this medical shoe is optically balanced so that the shoe can easily be integrated into everyday life. Thanks to the pneumatic compression of the sole of the foot, the venous return of the lower extremities is increased. This helps to subside the lower legs and feet after long trips or long seating and can improve the effect of compression stockings. The mechanism of the PKF is effective for all kinds of venous insufficiency and can improve the health condition of the patient as well as his quality of life.
