Fig 1. Overview of the components of the shoes and vibrating insole that apply mechanical vibration.

(A) The components of the shoes that apply the mechanical vibration to the soles of the feet. The main components are the vibrating insoles that contains the actuators that deliver mechanical vibration, a foam sole placed on top of the insoles to act as a shock absorber, and main body of the shoe that contains the connection pin and charging port to recharge battery. (B) The top and bottom view of the vibrating insoles. The top view shows the position of pair of actuators used to deliver the vibration to the metatarsal head (front actuators) and heel (rear actuators). The amplitude of the vibration is controlled independently for the two pairs of actuators, which allows users to apply the vibration to different areas of the foot with different amplitudes. The bottom view shows the position of the portable battery and the connection pin for the charging port of the shoes.
