These incredible Vtruvian Massage Slippers are specially designed according to acupressure points’ technique in Chinese traditional medicine. Acupressure is an ancient healing art that uses key pressure points on the surface of the skin to stimulate the body’s natural self-curative abilities. When these points are pressed, they release muscular tension and promote blood circulation and the body’s life force to aid healing. Our shoes will actively stimulate these pressure points while you are wearing them (walking or standing), to help relieve headaches, migraines, stomach aches, tiredness etc.
