Abstract:
A shoe comprising a base designed to make contact with the ground, an upper to cover the top of the foot, and an inner sole made partly of a first material which can be plastically thermoformed when heated to a given temperature for a given period of time and partly of a second material that can be formed under the weight of a body after a given period of time; the upper and the base forming a total internal shoe volume; the inner sole having a second volume that is smaller than the total internal volume so as to allow the formation, between the base and the inner sole, of at least one space forming a complementary, variable empty volume which combined with the second volume and a working volume forms the total internal volume; and where the first material and the second material of the inner sole are designed to be adapted and shaped to the individual shape of the foot when the latter is placed in the shoe;wherein the inner sole has at least one through hole that forms a seating, the inner sole being designed to be positioned in the shoe in such a way that the seating in the inner sole is coaxially aligned with a seating in the base so as to enable the insertion of a fastening element into both seatings to fix the inner sole to the base;wherein the seating in the base goes right through the base, a tubular insert being securely fixed inside the seating in the base and having, on one side, means of contact with a floor, and, on another side, means for electrically connecting the tubular insert with the fastening element so that static electricity can be discharged to the floor; andwherein the contact means consist of a ball made of conductive metal material, a portion of which protrudes from the lower end of the tubular insert and is in contact with the floor; the ball being acted upon by spring means placed on the inside of the tubular insert positioned between the ball and the upper end of the insert and being designed to keep the ball in contact with the floor depending on the contact thickness of the base on the floor.
