The third projecting piece 20 is set to the same size as the first main projecting piece 17a. For this reason, the movement in the left-right direction is effectively received by the position, direction, and length of the third projecting piece 20, and functions effectively during the dash in the left-right direction. The third projecting piece 20 works effectively on the kicking foot when starting running and touching up. When twisting, the inner line connecting the first main projecting piece 17a, the inner first sub projecting piece 17b, and the third projecting piece 20 works effectively.

  Next, the rear spike metal fitting 14 will be described. As shown in FIG. 1, the rear spike fitting 14 is located on the arch side of the foot when the baseball shoe 10 is worn and is formed on the heel side with a pair of fourth projecting pieces 26 formed in a C shape. A pair of fifth protrusions 27 formed in an inverted C shape are integrally formed by bending the outer peripheral edge of the annular coupling plate 28. As shown in FIG. 3, the annular coupling plate 28 is formed in a substantially inverted trapezoidal annular shape from a steel material, and each projecting piece 22 is located at the position of the two-dot chain line in the figure so that the outer peripheral edge portion, that is, the projecting portion 22 a is suspended. It is bent and formed. The thickness of the annular coupling plate 28 is set to the same thickness as the annular coupling plate 21. The shape of each protrusion 22 is set to be the same as that of the second protrusion 18.

  The pair of fourth projecting pieces 26 a and 26 b are set so that the extending direction thereof is approximately 45 degrees in the opposite direction to the central axis 16. The pair of fifth projecting pieces 27 a and 27 b are set so that the extending direction thereof is approximately 70 degrees in the opposite direction with respect to the central axis 16. The fourth projecting pieces 26a and 26b and the fifth projecting pieces 27a and 27b can receive movements in both the front-rear direction and the left-right direction.

  Specifically, the inner fourth projecting piece 26a and the outer fourth projecting piece 26b effectively act on various kinds of movements including the start of the running rod and the movement near the base. The inner fifth projecting piece 27a works effectively with the third projecting piece 20 against various movements in addition to the kicking foot when the running rod starts. The outer fifth projecting piece 27b is effective not only for twisting, but also effectively acts on the kick foot when starting running. Since the six projecting pieces 22 provided on the front spike metal fitting 13 are integrally formed by the annular connecting plate 21, the projecting pieces 22 can express functions synergistically. In addition, since the four projecting pieces 22 provided on the rear spike metal fitting 14 are integrally formed by the annular coupling plate 28, the projecting pieces 22 can express functions synergistically. Further, these ten projecting pieces 22 can function and synergistically exert an effect.

  As shown in FIG. 4, the spike fittings 13 and 14 of the baseball shoe 10 attached to the right foot are symmetrical with the front spike fitting 13 of the baseball shoe 10 attached to the left foot. The back spike metal fitting 14 is fixed to the shoe sole 12 so as to be symmetrical with the rear spike metal fitting 14 of the baseball shoe 10 attached to the left foot. Each protruding piece 22 of the rear spike fitting 14 exhibits the same function as each protruding piece 22 of the front spike fitting 13. Then, the right foot spike fittings 13 and 14 act as axial feet or kick feet with respect to movements such as the start of running, and exert their effects.

The effect | action by the spike metal fittings 13 and 14 of the baseball shoe 10 comprised as mentioned above is demonstrated.
Now, when running on the ground 15 with the baseball shoes 10 on, in the forward running (straight running), the running force is increased by the first protruding piece 17 including the first main protruding piece 17a and the pair of first auxiliary protruding pieces 17b and 17c. Created and able to start dash. When landing, the vehicle lands on the outer first sub-projection piece 17c and moves to the inner first sub-projection piece 17b. At this time, since the third protruding piece 20 is provided in the vicinity of the inner edge 19 of the baseball shoe 10, the weight is received by the inner first auxiliary protruding piece 17b and the third protruding piece 20, and the kick foot Can be used. Further, at the time of starting in the horizontal direction such as touch-up start, the third projecting piece 20 provided on a line extending from the thumb to the thumb ball functions most effectively, and an excellent start dash can be obtained.

  When the pitcher throws a ball, the weight is shifted from the heel to the toe side in the case of overslow, and the second protrusion 18a and the third protrusion on the inner side of the front spike fitting 13 from the fourth protrusion 26 of the rear spike fitting 14 are performed. A force is sequentially applied to the piece 20 and the inner first sub-projection piece 17b. In particular, in the case of three quarter throw, side throw, and under throw, a force is applied to the line from the thumb to the thumb ball. For this reason, the inner second projecting piece 18a, the third projecting piece 20, and the inner first sub projecting piece 17b function effectively, and can firmly grasp (grab) the ground. Furthermore, in the case of a fielder, although there are strengths when throwing a short distance, a gap, and a long distance, the same weight shift is performed, and the weight shift can be appropriately handled. Therefore, it is possible to perform the pitching powerfully and accurately.

  If the batter is standing and hitting the batter box, fix the foot to the batter box with the shaft foot slightly cross-shaped. At this time, the inner first sub projecting piece 17b, the first main projecting piece 17a, and the inner second projecting piece 18a work effectively around the third projecting piece 20. The stepping foot exerts the same force on each protruding piece 22 as when running. Then, the knee and waist of the shaft foot and the receiving foot are rotated inward, and the reaction force (power) obtained from the ground is effectively transmitted to the upper body by the rotation of the lower body.

  Common to the running, throwing and hitting actions is the point where a torsional force is applied from the thumb to the thumbball line, and the torsion is obtained by sufficiently receiving the torsional force. Running force, throwing force and striking force can be expressed by reaction force based on twisting.

The effect exhibited by the above embodiment is described collectively below.
