You can wear a pair of shaping shoes with high front and low back. There are many repeat buyers. The front of the sole is high and the back is low, which is the same as the principle of dance body training. Forcing the human body's center of gravity to move backward, the pelvis is corrected, and the spine is naturally straight, because the pelvis is the foundation of the spine. As the saying goes: hunchback, the waist does not collapse forward, and the back is difficult to camel. As a principle, when a person stands straight, the center of gravity must be in the heel. On the contrary, if the center of gravity is forced on the heel, the posture of the human body will tend to be straight. You can try, barefoot, stepping on a book about 18 mm thick to see if your posture is straight and your hunchback is reduced.
