Tropical Shiatsu Massaging Unisex Full-Length Insoles are like having three insoles in one: Shiatsu massage reflexology therapy and magnetic therapy. Covered with nodules that apply gentle pressure to vital acupressure points these Shiatsu massaging insoles simulate the deep kneading of a massage therapist promoting overall well-being and relieving foot pain. Magnets embedded in the insoles increase circulation while air holes keep your feet dry (Caution: Not recommended for people with fractures and broken bones). Reflexology benefits include improved blood circulation relief from lower back pain and excellent arch support. The magnetic therapy aspect relaxes muscle tension relieves pain and speeds up the healing process.
