First, in the shoe according to the first embodiment of the present invention shown in FIGS. so that when one foot stands on the ground, one point of the top axis of the conically formed top pivots on the ground.

When one point of the top shaft of the top comes to pivotally abut against the ground in this way, the upper part of the top body tends to wobble in all directions and is about to topple over. Since the round-shaped sole portion 12 is formed like a top shaft, the wearer wearing the shoes according to the present invention may fall, but when wearing such shoes on both feet, the wearer may fall. If you step on the ground, the left and right swaying is minimized, making it easier for beginners to stand on the ground.

As described above, by wearing a pair of left and right shoes having the round sole portion 12, lateral movement can be minimized, but the forward and backward rolling action is likely to occur, and the wearer can move forward and backward. Try to stand up properly while balancing your body so you don't fall over.

In such a state, when one foot is lifted for walking or exercise and only the other foot is in contact with the ground, one point of the top axis of the top is in pivotal contact with the ground as described above. Thus, when one point in the lower central portion of the round sole portion 12 corresponding to the top axis contacts the ground, the wearer's body swings in 360-degree directions.

If the wearer were to stand on one leg in this way, and would fall, the wearer would move his or her body to balance in order not to fall. In addition, in the process of moving from the soles of the feet to the top of the head in response to the swinging of the round sole portion 12, the muscles of the body corresponding to the movements are tense, and these muscles are strengthened.

When trying to get the center of gravity on the round sole portion 12 as described above, the ankle and calf muscles are used to train the muscles, and then by applying force to the thighs for balance. The thigh muscles are improved and the body is balanced, the abdominal muscles, back muscles, and buttocks, which are the core muscles located in the trunk, are stimulated to restore the body balance, and the waist muscles are stimulated to restore the lost balance. The wrong posture due to the posture will be corrected.

As shown in FIGS. 4 and 5, during the rolling action of the round sole portion 12 as described above, if too much rolling action occurs, the front and rear end portions of the sole body 11 may be deformed. The rolling action of the round sole portion 12 is stopped by the front and rear stop portions 15 and 16 formed in the front and rear ends, thereby minimizing overturning.

That is, when rolling is performed in the front-rear direction with only the round bottom surface of the round sole portion 12 in contact with the ground, the rolling action continues to occur due to the round bottom surface. Between the front and rear end portions of the sole body 11, front and rear stop portions 15 and 16 are formed at predetermined intervals. Rolling motion is stopped while the surfaces touch the ground together to stop excessive rolling motion, thereby minimizing tipping forwards and backwards.

A heel support portion 14 is formed in the heel portion of the sole body 11 to wrap and support the heel. The support part 14 wraps and supports the wearer's heel, so that the ankle is firmly supported by applying force to the wearer's ankle, so that the ankle can be rolled in a correct posture without shifting the angle of the ankle. This will help prevent falls and ankle injuries.

Next, a second embodiment of the sole 10 shown in FIGS. 6 and 7 is shown.
