If the ball part 200 is made of a soft material and the little ball part 2 1 0 is made of a hard material, the ball part sinks downward when kicking the foot, and the lateral direction It becomes easy to move the center of gravity smoothly. This makes it suitable for sports such as basket poles, tuss, valley poles, and suckers that need to move sideways. Here, the soft material refers to a material that is extremely shock-absorbing and feels sinking in the foot. Hard materials refer to materials that have a repulsive force that does not place a burden on the foot and that support the foot from below. Regarding the hardness of soft materials and hard materials, the hardness of soft materials is based on ASTM (American Society F or Testing and Materials, abbreviation for American Material Testing Association) standard. Suitable for AS TMD 2240 scaler 40-40 degrees. On the other hand, the hardness of the hard material is suitably 60 to 80 degrees on the same scale. Therefore, it is preferable that the hardness difference between the soft material and the hard material is at least 10 degrees or more on the same scale. The specific measuring instrument used for the above scale is Dutorometers / PTC (registered trademark) 400 S ER IES / Mode 1 4 1 1 / Ty pe OO manufactured by Pacific Transducer Corp. is there.

This makes it easier to move the center of gravity smoothly in the straight direction. This makes it suitable for sports such as walking, mountain climbing, and bicycles that require moving in a straight direction. Here, the hard material refers to a material that has a repulsive force that does not place a burden on the foot and that feels to support the foot from below. Soft materials are materials that are extremely shock-absorbing and feel the sinking of the foot. As for the hardness of the soft material and the hard material, those within the respective hardness ranges can be selected as in the case of Example 1. However, the hardness difference between the soft material and the hard material is at least 10 degrees or more on the same scale. Preferably there is. The ball part 200 and the little ball part 2 1 0 and the buttocks part 220 are made of shock-absorbing material made of urethane or other material that is difficult to loosen, and the arch member 230 is repulsive, such as nylon If soft materials are used for the baseball ball member 200, the small ball part member 210, and the buttocks member 220, Shock absorption corresponding to fingerball pain, little fingerball pain, and colic is possible. In addition, when a hard material is used for the arch member 2 30, the support of the arch is strengthened, and the health of the foot can be maintained or improved. In addition, it can help you improve your exercise performance because you can step on it when you kick your foot. Here, the soft material refers to a material that is extremely excellent in shock absorption and feels the sinking of the foot. Hard materials refer to materials that have a repulsive force that does not place a burden on the foot and that feel the foot supported from below. If a soft material is used for the arch member 2 30, the support of the arch will be weakened, and it will be possible to maintain and improve the health of the foot without placing a burden on the foot. In addition, regarding the hardness of the soft material and hard material, by selecting materials with different hardness for each member 2 0 0, 2 1 0, 2 2 0, 2 3 0, various functions that match the purpose of use Can be given. Also, as shown in Fig. 7, there is a gap between the arch member 2 30 and the inner bottom of the shoe, as shown in Fig. 7. As a result, it is possible to support the arch of the foot without impairing the movement of the foot, and to improve the performance of the exercise.
