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.

Abstract: The present invention relates to an insole installed inside a shoe to contact each foot sole portion of the human forefoot (A), midfoot (C) and rearfoot (B), which is made of a plurality of materials having varying degrees of hardness depending on the insole region, wherein the respective materials are combined to form a single layer. Preferably, the insole for a shoe comprises: a base plate with any one of a forefoot hole, a midfoot hole and a rearfoot hole formed therein corresponding to one of respective foot regions (A), (B) and (C); and an inner plate including one or more of a forefoot support, midfoot support and rearfoot support to be inserted into one of the holes, and, respectively, wherein the base plate and the inner plate are manufactured with materials having varying degrees of hardness relative to one another.

Abstract: The present invention relates to a toe cap for footwear which can improve the wearing feeling and the fitting feeling, and can protect toes from a strong external impact, and an outsole integrated with the same. Disclosed is a toe cap for footwear characterized by a first feature, wherein the toe cap is highest at a big toe region and gradually slopes downward toward the little toe; and a second feature, wherein the top cap has the shape of a circular arc along the outer shape of the toes and first to fourth grooves are formed at four positions between the five toes, respectively, so as to support each toe. In addition the outsole integrated with the toe cap is characterized by having a support groove which is formed at a front upper end surface to accommodate the bottom surface of at least one or more of the toes.

Abstract: The present invention relates to the last for manufacturing a shoe, and the purpose of the present invention is to provide a comfortable shoe having a nice sensation when worn by manufacturing shoe using a last having the same shape as that of a human foot during walking has been examined in the present invention by using biomechanical data of the foot, and more particularly, by a last comprising: a first protruding portion which is forwardly and upwardly rounded at one side at front end of a forefoot portion of the last, corresponding to a human big toe; a convex-concave portion at the front end of the forefoot of the last, corresponding to the shapes of each of a human being's second to fifth toe.

Abstract: Disclosed is a shoe sole capable of horizontally maintaining an inner bottom section of footwear when the user walks. The shoe sole includes an outsole provided at front and rear portions thereof with a plurality of protrusions, a mid-sole stacked on the upper surface of the outsole and formed with a plurality of perforation holes, an insert provided at a bottom surface thereof with a plurality of protrusions, which are inserted into the outer wheels by passing through the perforation holes of the mid-sole, and a lasting board stacked on an upper surface of the insert coupled with the mid-sole. The inner bottom section of footwear is horizontally maintained. The shoe sole attenuates foot fatigue and provides comfortable wearing feeling when the user walks on an unpaved road or climbs a mountain.
