These are the socks that contains an electrotherapy system to conveniently deliver pain relief to the entire foot. Using Transcutaneous Electrical Nerve Stimulation (TENS), thin silver wires imperceptibly sewn into the comfortable sock conduct harmless low-frequency electrical pulses to the foot. This drug-free treatment¿the same used by physical therapists and other medical professionals¿increases blood flow to promote healing and minimize pain caused by arthritis and plantar fasciitis. The sock maintains full contact with the foot's entire surface, including the ankle, providing all-over therapy without having to reposition electrodes as with standard TENS devices. Its tethered controller offers six different modes and 20 intensity levels to provide customized relief, with settings clearly displayed on a large LCD screen. Rechargeable lithium ion battery provides 15 hours of treatment from an eight-hour charge using the included AC adapter. Hand wash. Includes left and right socks, electrode wires, and two gel pads. One size fits most.
