Abstract:
A footwear comprising:an outsole having a heel portion and defining a reference plane that is adapted to form an angle with a ground surface when said heel portion is lifted above the ground surface and that is adapted to be parallel to the ground surface when said heel portion is in contact with the ground surface; a stand projecting upwardly from said outsole and having an inclined upper surface that is inclined relative to the reference plane; a power generator mounted on said outsole and including a rotor that is rotatable about an axis, and a stator magnetically associated with said rotor for generating power upon rotation of said rotor; and a driving unit including a weight that has a pivot end mounted pivotally on said inclined upper surface, and a free end opposite to said pivot end, and that is connected to said rotor, said free end of said weight being swingable by virtue of gravity when said inclined upper surface of said stand is swung back and forth as a result of upward and downward movements of said heel portion within said angle, thereby driving said rotor to rotate back and forth so as to permit actuation of said power generator to generate power.
