Abstract: A method of manufacturing a footwear sole includes providing a base sole, and performing an electrostatic flocking process to bond a leather material layer onto a portion of the base sole. The electrostatic flocking process includes the steps of applying an adhesive material to cover a surface of the base sole, providing a leather flock source, spraying electrically charged leather flock onto the adhesive covered surface of the base sole, and curing the base sole to bond the leather flock to the surface of the base sole. The method is described principally with respect to applying a leather material layer to a surface of a base sole, and the method may be employed to apply a leather material layer to shoe portions other than a surface of the base sole, such as a surface of the outer sole, insole, or inner sole, or a surface of a whole shoe.
