The TensCare iSock is a wearable electrode for TENS and EMS machines which uses conductive fabric to  allow the stimulation from the TENS unit to pass throughout the foot to improve bloodflow, mobility and to provide relief from pain.  The iSock works in the same way as an electrode pad but targets the whole of the foot providing the best relief for foot pain. It receives the electrical impulses from a TENS or EMS unit and conducts these though the silver thread within the garment. It stimulates the nerve endings and relieves the symptoms of foot pain and arthritis, reduces swelling, and rehabilitates muscles to increase mobility. The thin and flexible fabric of the iSock means it can be worn under clothes and while moving around, so you can reduce pain and return to an active lifestyle.   Medium: Suitable for UK shoe sizes 4 to 8 Large: Suitable for UK shoe sizes 9 and larger   This item requires an EMS or TENS unit, Recommended TENS machines for use with are iSock are the Perfect TENS and the Sports TENS.
