2. The heel length of high-heeled shoes is moderate, which helps the calves to grow longer and reduce swelling.

However, the high height of high heels will have many adverse effects on the body. According to experimental observation, the heel height of high-heeled shoes is 2~3 cm. If it is too high, the center of gravity of the human body moves forward too much, and the body weight moves too much to the forefoot, so that the toes are squeezed and deformed. After a long time, it is not only painful, but also prone to foot diseases such as corns and mats. In addition, the heel is too high, which changes the normal posture when walking. The waist is too straight, the buttocks are prominent, the knee joint is in a stiff state, and the calf muscles are not properly relaxed and rested, which is prone to fatigue, low back pain and other symptoms. It is difficult to keep balance when walking in high heels, and it is easy to cause lower limb sprain, especially ankle sprain. Developing girls, obese and tall girls are not suitable for wearing high heels.
