Available only from Hammacher Schlemmer, this is the device that uses Shiatsu massage, TENS therapy, and heat to relieve pain, improve circulation, and sooth muscles in the feet and calves.

The feet are targeted with transcutaneous electrical nerve stimulation (TENS) therapy that provides drug-free pain relief and soothing heat up to 112° F. A free iOS/Android app enables one to control the device using a smartphone. With 50 program modes, 99 TENS intensity levels, and auto shut-off. Not for those who are pregnant, use pacemakers, or have blood clots. AC adapter. 17 3/4" L x 15" W x 12 1/4" D. (19 lbs.)
