Foot Massager: Locate those sensitive spots on your feet by gently probing with both ends of this tool. If you're unsure where they are, experiment and pay attention to how your body responds. You can't cause yourself harm, but you might accidentally hit a particularly tender spot - and that's actually what you're aiming for. Use both parts, as one is designed to fit into the contours of each foot.
