The curved sole keeps the wearer in an unstable state all the time. In order to keep the balance, the wearer needs to constantly adjust the muscles and bones of all parts of the sole to balance and support comprehensively, so that the muscle groups of the foot can be effectively exercised, which not only consumes excess fat, but also keeps the posture of the upper body straight. At the same time, the support column located in the center of the sole can continuously massage the soles of feet, promote the blood circulation of [1] feet, and ensure good health. Swing shoes, especially sandals and flip-flops, are not suitable for teenagers with unstable center of gravity and incomplete bone development when going downstairs or downhill. Shoe-shaking violates the physiological structure of human feet. There are several stress points on the sole of the foot, two on the forefoot, one on the heel and one on the ankle. These points are in equilibrium with each other. Wearing rocking shoes will inevitably change the stress state, which does not meet the needs of physiological structure, and even change the structure of arch. The skeleton structure of teenagers is not fully developed, and it is not suitable for wearing.
