The Kanjo Vibrating Acupressure Foot Pain Relief Ball offers a versatile at-home solution for foot pain. Taken from ancient Eastern methodologies used in acupuncture, the Ball targets acupressure points to reduce pain in the feet, while vibration calms, relaxes and soothes. The Kanjo Vibrating Acupressure Foot Pain Relief Ball alleviates general foot, heel and arch pain caused by plantar fasciitis, running, walking, and working on your feet. Traditional Chinese Medicine (TCM) believes that chi (or qi) is the healing energy that flows throughout the human body by way of meridian pathways. Blockages in these pathways can cause various aches, pains, and spasms. Acupressure therapy is used to target, engage, and relieve specific meridian pathways, reducing any discomfort. Several vibration settings, from mild to more intense, from steady to intermittent, relax muscles to alleviate pain. Built-in rechargeable battery. FSA/HSA eligible.
