Abstract: The present invention relates to a method for manufacturing spikes for sports shoes, the method comprising: a primary injection-molding step for fixing a plurality of spike pin heads to one surface of a first fixed plate when injection-molding the first fixed plate such that the tip ends of the plurality of spike pins are exposed through the surface of the first fixed plate; a secondary injection-molding step for fixing a plurality of first fixed plates to one surface of a second fixed plate when injection-molding the second fixed plate, wherein the surfaces of the first fixed plates that are opposite to the surfaces to which the spike pines are fixed to the second fixed plate; and a second-fixed-plate fixing step for fixing, to the bottom of an outsole, the surface of the second fixed plate opposite to the surface to which the first fixed plates are fixed.
