Rolling shiatsu, scraping, heating and compression functions in this foot and calf massager work together to relax muscles and support circulation. The 23 x 18 x 9 in ABS housing contains air bags that squeeze at 5 intensities while constant heat warms your feet. Five massage modes and 2 vibration levels let you focus on different areas and tailor each session. A rotary supporting stand adjusts the angle for feet, calves or arms and doubles as a handle for moving the unit between rooms when needed.
