1. An electrical stimulation apparatus, comprising:

  • a shoe insert shaped to be inserted into a shoe;

    at least one piezoelectric member disposed in the shoe insert, the at least one piezoelectric member having an active and an inactive state, such that the piezoelectric member generates electrical energy when in the active state;

    at least one electrode disposed in the shoe insert, the at least one electrode electrically connected to the at least one piezoelectric member, such that when the at least one piezoelectric member sends electrical energy to the at least one electrode, the at least one electrode provides electrical stimulation to a user in contact with the at least one electrode; and

    the at least one electrode including a plurality of layers, with a first layer of the at least one electrode comprising a metal integral conductive silicon rubber material, with the first layer positioned most proximate to the user, and with a second layer of the at least one electrode positioned adjacent the first layer, the second layer comprising a conductive adhesive gel material.
