The FM39 foot massager utilizes the added benefit of infrared heat which provides soothing warmth that helps improve blood circulation enabling your muscles to relax. Eight powerful counter rotating massage discs work on the base of your foot to soothe and relax tensed muscles, alleviating stress and tiredness whilst also reviving and regenerating. Easy to operate, even when sitting down; you can simply operate the controls with your toe. The two settings can be selected with or without the heating feature. The compact and lightweight design allows you to quickly and easily move the unit around your home.
