The Naipo foot massager can be used for a complete massage of the feet. The shaking function is a unique feature. Many foot machines on the market do not offer this function. The design concept of this feature aims to alleviate psychological anxiety and tension through foot shaking or other body language. A small stimulation of a specific body part can relax the mind. Therefore, high-frequency shaking on the soles of the feet can lead to a simultaneous relaxation of both body and mind.
