What is the principle of dynamic step functional physiotherapy health shoes?

Black technology integrating micro-current and magnetic reed vibration. Magnets and vibrating reeds are reasonably added to the bottom of shoes. Based on the principle that magnets repel each other, when walking, the human body's own movement causes two reeds to vibrate, so that the two reeds are close to each other, and then the magnets with the same polarity repel each other, so that people can massage their feet at any time while walking and achieve the same effect as pedicure.
