Description

  The present invention relates to spike shoes, and more particularly to the structure of the sole of a spike shoe used in sports.

  Conventionally, as spike shoes used in sports, for example, those having the structure shown in FIGS. 7 and 8 are widely known. FIG. 7 is a perspective view showing the external configuration of the conventional spike shoe 1, and FIG. 8 is a bottom view showing the external configuration of the conventional spike shoe 1.

  As shown in FIG. 1, a conventional spike shoe 1 mainly includes an upper 2 that covers the upper of the foot and an outsole 3 that is a ground contact bottom that covers the sole. Although not shown, a midsole for absorbing an impact at the time of grounding is mounted on the upper side of the outsole. The outsole 3, the midsole, and the upper 2 are integrally fixed by sewing 5 and bonding. In addition, a spike fitting 4 is fixed to the surface of the outsole 3 with a rivet or the like, and this fitting allows the spike shoe user to rapidly move back and forth and to the left and right.

  Here, when the user of spike shoes dash forward, he / she gains forward force by the force of kicking the ground, so in order to realize a quick start, high resilience elasticity in the front / rear direction of the spike shoes is required . This is because if the rebound resilience is low, the force of kicking the ground is absorbed. Usually, the rebound resilience in the front-rear direction of this spike shoe is mainly due to the material and structure of the outsole.

Therefore, in conventional spiked shoes, as the outsole, a leather outsole modeled from a piece of cowhide having high rigidity and high resilience, or a synthetic resin having the same performance as this leather outsole is often used. It is used. For example, as a conventional spike shoe, what is shown in the following patent document 1 is known.
JP-A-8-205906

  However, in the conventional spike shoes, since the high resilience material is used for the outsole as described above, the torsional rigidity in the left-right torsion direction of the shoe is increased. In sports using spike shoes, there are many sports that move violently forward, backward, left and right, and spike shoes with strong torsional rigidity have a problem that movement in the left-right direction is limited.

  Here, the spike shoe disclosed in Patent Document 1 has a configuration in which the outsole is divided into a front outsole and a rear outsole, and the front and rear outsole are joined by a connecting member. However, in Patent Document 1, the reason that the outsole is divided into two is to make the interval between the front and rear outsole variable so that the size of the foot of the spike shoe is variable. For this reason, in the spike shoe of patent document 1, the high rigidity and the high rebound resilience in the front-back direction are lost, and there is a problem that the force that kicks the ground when the user dashes forward is absorbed by the spike shoe. It will occur.

  The present invention has been made to solve such a problem, and provides a lightweight spike shoe in which the torsional rigidity in the left-right direction is reduced while maintaining high rigidity in the front-rear direction and high resilience. For the purpose.

  The spike shoe according to the present invention is an outsole that is in contact with the ground, and includes an outsole composed of a front outsole and a rear outsole divided in the front-rear direction, the front outsole on the upper surface of the outsole, and the A connecting midsole that is fixed integrally with the rear outsole and connects the front outsole and the rear outsole, and is formed of a resin that has lower mass, rigidity, and rebound resilience than the material of the outsole. A connecting midsole, a midsole integrally fixed to the upper surface of the connecting midsole and formed from an elastic material, and a lasting board fixed integrally to the upper surface of the midsole, the connecting midsole and the Lasting bow that is fixed together with the outsole by stitching with the midsole in between When, characterized by comprising a an upper for covering the instep in the upper than the lasting board.

  ADVANTAGE OF THE INVENTION According to this invention, while maintaining the high rigidity and high resilience of the front-back direction, the lightweight spike shoes which reduced the torsional rigidity of the left-right direction can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the present embodiment, a baseball spike shoe will be described as an example of a spike shoe.

  First, the configuration of the spike shoe according to the present embodiment will be described. FIG. 1 is a bottom view of the spike shoe 10 according to the present embodiment, and FIG. 2 is an end view taken along line AA of the spike shoe 10 shown in FIG. As shown in FIG. 2, the spike shoe 10 is located above the sole (sole) portion of the shoe and is located below the sole portion of the shoe, and the upper structure 13 shaped to cover the instep. And a sole structure 14 having an outsole that contacts the ground. As will be described later, the upper structure 13 and the shoe sole structure 14 are integrally fixed by stitching or adhesion.

  The upper structure 13 is inserted into the upper 12 so as to cover the instep of the foot above the sole portion so that the upper and lower portions are open, and the upper structure 13 is inserted into the upper 12 so as to come into contact with the sole of the user. And sockliner 20. Thereby, upper 12 of spike shoes 10 is constituted in the shape of a bag which can store a user's foot. As the material of the upper 12, leather, synthetic leather, synthetic fiber or the like is used. The sockliner 20 is formed from a material having cushioning properties, and provides comfortable comfort for the user.

  In addition, the upper 12 is provided with a collar 16 for protecting the instep of the wearer at one upper opening. A lasting board 17 of a shoe sole structure 14 to be described later is attached to the other lower opening.

  Next, the configuration of the shoe sole structure 14 will be further described with reference to FIG. FIG. 3 is an exploded perspective view showing the configuration of the spike shoe 10 according to the present embodiment. As shown in FIGS. 2 and 3, the sole structure 14 includes a lasting board 17, a nonwoven fabric sheet 22, a midsole 24, a wedge 26, a front outsole 28, and a rear outsole 30 from the top to the bottom. The front metal fitting 32 and the rear metal fitting 34, and the rivet 36 and the washer 38 for attaching and fixing the front metal fitting 32 and the rear metal fitting 34 are constituted.

  The spike shoe 10 according to the present embodiment thus divides the outsole into the front and back, a part functions as the outsole, and is fixed integrally with the front and rear outsole to connect the two. It features a wedge that functions as a midsole. With this configuration, the spike shoe 10 is reduced in weight, and also maintains high rigidity in the front-rear direction and high rebound resilience, and reduces the torsional rigidity in the left-right direction.

  The lasting board (also referred to as an insole board) 17 is attached to the upper 12 by stitching or bonding, and is also coupled to other members of the shoe sole structure 14 by stitching or bonding. As a material of the lasting board 17, materials such as non-woven fabric, pulp board, leather, or resin are used. In the present embodiment, the lasting board 17 is configured by combining a front side lasting board 18 made of leather with a rough surface and a rear side lasting board 19 made of a nonwoven fabric. By using leather as the material on the front side of the lasting board, it is possible to prevent slipping of the toe portion that becomes the center of gravity when the user dashes.
