Description

[Detailed description of the invention] This invention is mainly concerned with improving the sole suitable for golf shoes, and allows the sole to adapt to the movement of the foot in the front-rear direction, torsion direction, and width direction without feeling any resistance when walking or playing. The purpose of this is to sufficiently transmit the movement of the foot to the shoe, making it effective for playing, and reducing foot fatigue.

In recent years, synthetic resin soles have been used for golf shoes, and one type of sole is a composite molded sole of low-hardness and high-hardness synthetic resins. The structure of such composite molded soles consists of a core made of high-hardness synthetic resin and covered with low-hardness synthetic resin, and a high-hardness synthetic resin integrally formed in the heel and front contact areas of the low-hardness synthetic resin. The purpose of this method is to strengthen the adhesion of the spikes and to alleviate the thrusting of the soles of the feet by embedding the base plate or female metal fittings of the spikes in a high-hardness synthetic resin. However, high-hardness synthetic resins are rigid and have poor flexibility, inhibiting the flexing of the entire shoe sole, and making it difficult to adapt to foot movements in the width direction and torsion direction. This had the disadvantage of causing early leg fatigue.

In addition, if the front ground contact part has rigidity over the entire surface and the ground contact part has low hardness and bends easily, the sole of the shoe will not exert any pressing force or kicking force during play, and the so-called ground resistance will be reduced. This had the disadvantage that the tension was insufficient, causing the body to lose its balance.

Therefore, this invention is intended to eliminate such drawbacks, and an embodiment thereof will be described with reference to the drawings.

That is, in a shoe sole made of a composite of a low-hardness synthetic resin A that is rich in flexibility and a high-hardness synthetic resin B that is rich in rigidity, only the front ground contact area and the spike fixation area of the heel are made of the high-hardness synthetic resin B. . As shown in the drawing, its structure is made of high-hardness synthetic resin B, and the front ground-contacting part is formed into band-shaped protrusions 4 and 5 on the outside 2 and the inside 3 excluding the toe part 1, and the band-like protrusion 4 on the outside 2 and The sole is mainly suitable for golf and is characterized by being connected to the heel part 6 by a rib 7 on the outside of the arch part.

As mentioned above, this invention effectively combines high hardness synthetic resin B with low hardness synthetic resin A,
By arranging the high-hardness synthetic resin B at the optimal location for walking and playing golf, the following effects are achieved.

In other words, while walking, the sole of the shoe repeatedly bends in the front-back direction, but the movement of ground pressure is not limited to just bending in the front-back direction, but also in the ground contact area as shown in Figure 3 A, B, and C. It also bends inward and twists inward as it walks. In this invention, a rib 7 is formed of high hardness synthetic resin B between the band-shaped protrusion 4 of the front ground contact part and the heel part 6 on the outside of the ground contact part,
Since the band-shaped convex parts 4 and 5 are separated and the high-hardness synthetic resin B is removed from the toe part 1, the part of the low-hardness synthetic resin A from the toe to the inside of the arch is twisted and bent inward, making it difficult to walk. Easily reduces leg fatigue.

Next, to describe the movement of the pressure applied to the sole of the shoe when playing golf, for a right-handed player, pressure is applied toward the inside of both feet at address, as shown in Figure 4 A, and in this case, the pressure applied to the sole of the shoe is Pressure acts on the heel part 6 of the bottom and the inner side 3 of the front ground contact part, but the inner side 3 is made of high hardness synthetic resin B and has a band-shaped protrusion 5.
Because it is formed, it can withstand pressure sufficiently and maintain a stable posture.

When taking a swing back with a golf club, pressure is applied to the outside of the right foot, so in this invention, a band-shaped protrusion 4 is formed with high hardness synthetic resin B on the outside 2 of the front ground contact part of the sole of the shoe. Since the heel portion 6 is connected to the heel portion 6 on the outside of the non-stepping portion by the rib 7, rigidity is generated toward the outside of the approximately entire length of the sole. This stiffness acts as a drag force and prevents pressure from escaping to the outside, so the force of stepping and kicking accumulates. At the same time, the left foot, which is the pivot foot, is pressed against the belt-like protrusion 5 on the inner side 3 of the front ground-contacting part, allowing the player to move from a stable posture of both feet to the next swing. (As shown in Figure 4 B) Furthermore, in the swing up to impact,
The pressure applied to the right foot moves from the heel 2 to the inner side 3 of the front ground contact area, and in particular, torsional stress is applied to the inner side 3 in the inward direction, but this idea uses high hardness synthetic resin B to move the inner side 3 and the outer side 2. By separating the band-shaped protruding parts 4 and 5 at the toe part 1, the band-shaped protruding parts 4 and 5 can easily twist inward from the missing part of the toe part 1, so that the movement of the foot is It becomes easier to adapt.

In the movement from impact to follow-through, as shown in FIG. Since it is connected to the band-shaped protruding portion 4 and is integrally imparted with rigidity, the stepping force will not escape to the outside, and even if the inner band-shaped protruding portion 5 of the right foot kicks strongly toward the left foot, the posture will not change. He can twist his upper body in the direction of the ball without breaking.

Therefore, when used in the soles of golf shoes, the soles adapt to foot movements and weight shifts from address to follow-through, and the necessary stepping and kicking acts effectively, which is beneficial for golf play. .
