1, there is shown a bottom layer 1 of an outsole 10 of the present invention, stiffeners 2 and 3 provided thereon, a grip member 4 and an upper 5 (upper). Shoe soles typically include insole, midsole and outsole. The present invention includes at least one of an insole and a midsole. It is not shown here. The bottom layer (1) is made of a material excellent in contact force against the ground or rock wall. A good material is T.D.R. (Thermo Dynamic Rubber). The material of the bottom layer of the outsole can be used by mixing and processing the chemical mixture at a specific ratio to meet the required application.

One of the requirements of high performance energy-saving tire dread rubber is to enhance the mutual attraction between filler and rubber by using special functionalized styrene-butadiene rubber (SBR) and coupling agent to simultaneously improve slipperiness and abrasion resistance on wet road surface. . In a preferred embodiment of the present invention, this technique is applied to a rock walling to provide a rocking outsole with a silica-based filler applied to the bottom layer 1 and / or the grip member 4 to increase the wet road surface friction.

Above the floor (1). That is, a first stiffener 2 is provided between the outsole and the insole in the form of a horseshoe along the toes on the front sole. The first stiffener 2 is higher than the hardness of the bottom layer 1. In a preferred embodiment of the present invention, the first stiffener comprises a metal, and the metal comprises steel, copper or aluminum. Referring to Fig. 2 (a), the forefoot of the first stiffener provides the bearing capacity of the climber at the edge or pocket of the rock. The climber is able to withstand and tolerate weight on one foot. Here, the first stiffener 2 extends in the form of a horseshoe along the toes of the front foot so that the force applied to the first stiffener is dispersed to the power generator through the front sole. Therefore, the toe hook can be reinforced as compared with the conventional rocking. In this specification, the sole of the human body is divided into a toe, a front foot, a middle foot, and a rear foot bottom in order from the toe to the heel, and the outer edge of the toe is referred to as a toe. The climber can then use the edges or pockets of the rock to support the body and continue climbing.

A U-shaped grip member 4 having a wide entrance width is provided on the bottom layer 1, that is, between the outsole and the insole and on the inside of the first stiffener 2 in the front foot area. The grip member 4 is lower in hardness than the bottom layer 1 and is made of a material having good elasticity. 2 (b), the rounded edge of the holder 8 is brought into contact with the inside of the U-shaped grip member 4, so that the soft property of the grip member 4 causes the grip member 4 to move toward the sole Let them enter. Since the rounded edge of the holder 8 enters the sole through the grip member 4, the supporting force against the edge is dispersed to the clitoral generator body, making the foot more comfortable. Even the climber can support and hold the weight on one foot, allowing the hand holding the hold to relax. In a preferred embodiment, a foamed elastic material is applied to a grip member to provide a ground surface area for a rocking outsole.

Above the floor (1). That is, a second stiffener 3 is provided between the outsole and the insole in the form of a horseshoe along the heel. The second stiffener 3 is higher than the hardness of the bottom layer 1. In a preferred embodiment of the present invention, the second stiffener comprises the same metal as the first stiffener, and the metal comprises steel, copper or aluminum. However, the present invention is not limited to this, and the second stiffener may be different from the material of the first stiffener. The second stiffener 3 is provided with hooking (a method of using the heel to hold the shoulder above the shoulder) or a heel hook (a method of supporting the body by supporting the heel to the point above the head for a while) So as to be able to endure. Here, the second stiffener 3 extends in the form of a horseshoe to the rear foot floor along the foot, so that the force applied to the second stiffener is dispersed in the power generator body through the hindpaw floor. Thus, the climber can hold one foot of the climber to the hold 8, hold the body, and continue climbing.

3, there is shown a relationship in which the stiffeners 2 and 3 and the grip member 4 according to the present invention are positioned on the bottom layer 1. As shown in Fig. In the present invention, the outsole includes a double layer having different physical properties. That is, at the toe region, a double layer of the bottom layer 1 and the first stiffener 2, a double layer of the bottom layer 1 and the second stiffener 3 at the bottom portion of the hindpaw, and a double layer of the bottom layer 1 and the grip member 4).

3 (a) shows a state in which the first stiffener 2 is placed on the cut portion of the toe portion of the bottom layer 1 and the grip member 4 is placed on the groove portion of the bottom layer 1 at a slight distance therefrom, And the second stiffener 3 is placed on the cut portion of the portion. The grip member (4) uses a front sole to provide a holding force to the holder (8).

 3 (b) shows a state in which the grip member 4 is placed at the cut portion from the toe portion to the front foot portion of the bottom layer 1 and the first stiffener 2 is placed at the cut portion at the front side of the grip member 4 Is set. A second stiffener (3) is placed on the cut portion of the hindpaw. The grip member (4) uses a front sole to provide a holding force to the holder (8). The grip region of the grip member 4 is wider than that of FIG. 3 (a).

3 (c) shows a state in which the first stiffener 2 is placed on the cut part of the toe part of the bottom layer 1, and the grip member 4 and the right side part of the toe Provides a grip member 4 'of different hardness. And the second stiffener 3 is placed on the cut part of the hind foot bottom part. Preferably, the grip member 4 'is lower in hardness than the grip member 4. Therefore, it is possible to hold the edge or the hold 8 of the rock at the depressed portion between the toe and the front sole, so that a stronger supporting force can be provided. On the contrary, the grip member 4 'may have a hardness higher than that of the grip member 4. In addition, the grip member (4) has different hardness at the large toe side and the small toe side of the wearer. Preferably, the hardness at the large toe side is stronger than the hardness at the small toe side.

3 (d) shows a state in which the stiffeners 2 and 3 and the grip member 4 are placed directly on the bottom layer 1 and the grip member 4 is formed in a circular arc shape corresponding to the grip member 4, The hardness of the site can be controlled. If the bottom layer 1 is made thin in an arc shape, it is convenient to ground the round hold 8.

In addition, when the hardness difference between the first stiffener 2 and the grip member 4 is large, it is possible to further reduce the feeling of fit, thereby further reducing the difference in hardness therebetween.

3 (a) to 3 (d) illustrate preferred embodiments of the present invention, which can be applied in combination with each other. As one variation, the stiffeners 2, 3, the grip member 4 and a part of the bottom layer can be placed on the floor touching the ground and the bottom layer 1 can be placed thereon.

Next, in another embodiment of the present invention, as shown in Fig. 4, the first stiffener 2 is formed so that the toe portion A of the wearer is narrowed and the young toe portion B is wide, (A ') is formed wider than the small toe side portion (B'). Accordingly, the force received by the first stiffener 2 can be more efficiently dispersed than the stiffener shown in Fig. 1, so that the holding force of the holder 8 can be further strengthened.

When the size of the holder is very large, it is supported through the entire front foot. When the size of the holder is slightly small, it is supported using the big toe portion. If the size of the holder is very small, It can effectively cope with various sizes.

5, there is shown an elastic band 6 extending from one side of the upper to the other side of the upper through the bottom layer of the outsole 10, in the rocking shown in the configuration of FIG.

In general shoes, especially shoemaking, the shank is part of the support structure between the insole and the outsole, which plays an important role in reducing the load caused by the wearer's feet and rock during climbing in the hiking. Generally, the shank is made of steel, and the secondary shank is often made of a rigid material, such as glass fibers or Kevlar, which have low thermal conductivity. The stiffness properties of these materials help prevent damage to the wearer ' s pores or stones. The shank also supports the force, prevents distortion, maintains the shape and supports the shape. To do this, the shank must be provided through the midsole.

However, in the embodiment according to the present invention shown in Figs. 1 to 4, there is no shank in the middle sole. Therefore, in the present invention, when the technique such as jamming, move, oppoistion, etc. is applied, there is a fear that the rocking is distorted and the foot is distorted accordingly. Therefore, in order to protect the foot, And the elastic band 6 attached to the side surface of the upper part are integrally formed. In the illustrated embodiment, two elastic bands 6 are provided crossing the floor, but only one elastic band may be used, and one or more elastic bands 6 may be provided on one side of the upper, the heel of the upper, And the other side of the upper. Elastic bands can be secured to the instep using upper shoelace or bellows.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
