[Detailed description of the invention]

B. Field of Industrial Application The present invention relates to golf shoes, and relates to golf shoes that have been devised and improved so that general golf players can swing shots toward the ball more accurately and reliably when playing golf. . B. Prior Art FIG. 1 shows the trajectory of a typical ideal golf swing. This principle is well known. However, even for many amateur golfers, it is not easy to swing as shown in Figure 1. In many cases, as shown in FIG. 2, during the initial backswing, movement including the body axis, that is, a body sway phenomenon generally occurs. In the ideal swing shown in Figure 1, the swing starts from point ``S'', moves down from ``S'' to ``T'' to ``H'' with a radius of rotation R, and the club is pushed out horizontally by ΔX. The apogee of club rotation becomes R+ΔX and shifts to "F". On the other hand, when the body sways as shown in Figure 2, the points "T" and "H" move by ΔX during the backswing, and the swing starts from point "S" and moves from "S" to "H". T” → “H′”
→ “H” → “F”, and the apogee of club rotation is R
-ΔX', and compared to the ideal swing, the swing becomes [R-(ΔX+ΔX')]. The time to actually hit the ball is delayed by the amount of movement of the body relative to ΔX, and when hitting the ball, the club face is at a point higher by ΔY as shown in Figure 2 and at an angle of θ as shown in Figure 4. , the situation becomes (L+θ), which is added to the loft angle L of the club (see FIG. 5). Therefore, the horizontal force F in the ideal swing (Figure 1) has an angle of θ as shown in Figure 4, resulting in a force F', which is reduced by the force △F. Become. That is, F>F' and F=△F
The relationship +F′ holds true. This shows that compared to the ideal flight distance chart a as shown in FIG. 5, the flight distance becomes shorter as shown in b. This relationship is shown in c. Next, we will show the relationship between the position of the player's feet and their position when keeping the ball. Figure 6 shows the relationship ``H'' between the ideal stance and the position of the ball, and Figure 7 shows ``S'', ``H'', and ``H'' when the body of a right-handed player moves toward the right foot by ΔR. ''' are shown. C. Problems to be solved As mentioned above, when an ordinary player makes a backswing to hit the ball, a situation occurs where the swing sways from the ideal swing situation to the rear side, that is, to the right foot side for a right-handed golfer. As a result, the flight distance is not great, and the point at which the ball is hit is not determined.
The direction in which the ball will be launched is also uncertain. D. Means for solving the problem Therefore, in the present invention, when performing a backswing, a right-handed batter can make an ideal swing without swaying to the right side from an ideal swing state. To do this, it applies a force in the opposite direction to compensate for the movement of the body weight when swaying, and in order to prevent the sway, the end of the foot in the sway direction is held high. In addition, we proposed golf shoes that have a slight slope during normal walking, but maintain the slope only when shooting, and the sole of the shoe on the rear side in the direction of ball hitting is a hard sole. It has a double structure with a soft bottom made of an elastic material provided above, and an inclined holding part made of a hard material is installed at the rear end of the soft bottom in the direction of ball hitting so as to be higher than the front end. It is characterized by E. Examples The present invention will be explained in detail with reference to examples shown in the figures below. Figures 8 and 9 show different foot situations with the position and angle of the foot of a right-handed player.
In the case of Figure 8, the left and right shoes are in a normal stance along the ground, and in the case of Figure 9,
Each figure shows the case where the right foot stands at an angle of α to the ground. Suppose that the weight on the player's right foot is W. In the case of the stance horizontal to the ground in Fig. 8, the weight W is applied perpendicularly to the ground, whereas in the case of Fig. 9, as shown in Fig. 11, the weight W is applied to the ground at an angle of α. Therefore, the weight W is perpendicular to the plane X-X', which has an angle of α to FIG.
It is perpendicular to X′. Therefore, in the case of Fig. 9, that is, α
If only the right foot holds the angle , a weight shift △W created by the angle α will occur from the right foot to the left foot. In other words, the force generated from the right foot to the left foot of △W is
As explained in the figure, when an ordinary player performs a backswing to hit the ball, the player's body moves from the ideal swing to the right side. The more ideal swing shown in FIG. 1 can be easily realized in the situations shown in FIGS. 9 and 10 without causing the player's body to sway by offsetting the force ΔW. However, when tilting the shoe on the rear side in the ball hitting direction, it is natural to tilt the shoe on the front side as well.
Moreover, it is possible to expect a countervailing force that synergizes with the above-mentioned countervailing force of △W, and there are the following three forms.

[Table] Of these, the effect is greatest when α>α'. Therefore,

The maximum effect can be ensured when [Table]. 13 to 15 show specific examples of the inclined holding portion that actually realizes the situations shown in FIGS. 9 and 10 of the present invention.
As shown in the figure. The same applies to the following, but in this embodiment, a golf shoe on the right foot side of a right-handed player will be described. As for the golf shoes on the left foot side, there are cases in which conventional ones are used, and there are cases in which they are formed in accordance with the golf shoes on the right foot side of the present invention, but with a lower height. Golf Shoes is a schematic diagram seen from the heel side. FIG. 12 shows the sole of a conventional golf shoe 1. The sole 2 is flat and has spike fittings 6 screwed into it. In this invention, the sole part 2
This is constructed by providing a soft sole 4 made of elastic plastic, soft rubber, or the like on a hard sole 3 made of leather, synthetic leather, synthetic rubber, or the like. The upper surface of the soft sole 4 is formed horizontally. The soft sole 4 is preferably fixed on the hard sole 3, but may simply be placed on the hard sole 3. 5
is an inclined holding part, which is made of a soft material such as soft rubber, plastic, wood, iron, or metal such as aluminum, and is formed into a flat plate shape, a square bar shape, a round bar shape, an inclined plate shape, or the like. The inclined holding part 5 is installed so as to be wrapped in the soft sole 4, but the heel part and the foot part may be formed separately and attached, or it may be formed in one piece over an appropriate length. . Further, the inclined holding part 5 can be installed to be curved to match the outer surface of the sole part 2 or to match the shape of the foot. Of course, the soft sole 4 may be formed integrally, or the heel portion and the foot portion may be formed separately. The height of this inclined holding part 5 is 5 to 40
mm is used, preferably 10 to 25 mm
is suitable. Moreover, it goes without saying that a padding material may be laid on the soft sole 4. It is used in the same way as regular golf shoes, but when the foot 7 rests on the soft sole 4, the soft sole 4 is pressed and compressed by the body weight. At this time, the soft sole 4 is slightly tilted toward the front end because the rear end is thinner than the front end due to the slope holding part 5 provided at the rear end in the ball hitting direction. , The pressure when walking is not as great as my husband's, and the height between the front and back is slightly different. Therefore, when walking, there is no inclination as much as my husband's, and there is no discomfort. However, when hitting a ball, the foot kicks toward the rear end, and the force of the foot is applied to the front end, strongly pressing the soft sole 4. At this time, of course, force is applied to the rear end, but it hits the inclined holding part 5 and prevents it from sinking due to further pressure, and as a result, the front part sinks greatly and is applied to the body via the legs 7 α as shown in FIG. An angle of ΔW is generated, and a force corresponding to the weight shift ΔW is generated. F. Functions and Effects of the Invention According to the present invention as described above, the sole of the shoe on the rear side in the ball hitting direction has a double structure of a hard sole and a soft sole made of an elastic material provided thereon. An inclined holding part made of a soft material is provided at the rear end of the ball in the direction of ball hitting, so that it is higher than the front end.
When walking, the foot rests on the sole of the shoe in almost the same way as a normal golf shoes, allowing the user to walk without feeling as uncomfortable as the husband.In the case of a right-handed golf player, the slanted holding part provided on the right edge of the shoe allows the ball to be easily held. When shooting,
The extent to which the soft sole of the foot is compressed is done in a state where it is inclined toward the front end, since the front end sinks deeply and the rear end is blocked. Therefore, by making the swing extremely accurate and increasing the flight distance of the ball as shown in Figs. 1 to 5, and by modifying the swing situation as shown in Fig. 6, it is possible to slice and swing in the target direction. Directionality can be significantly improved by suppressing hooks and the like. In addition, the present invention can enhance the same effect and produce effective results not only by changing the thickness and angle of the soles of both feet in the same direction, but also by changing the thickness of the soles of the right shoes of right-handed players.
