There are many causes of splayed feet, such as heredity, calcium deficiency, premature toddler, premature wearing of leather shoes, etc. But in the final analysis, it is caused by the unbalanced stress on the feet. The inner splayed foot is the force on the inner side of the forefoot, and the heel rotates and deforms under this force. Over time, the deformation of foot bones, ankles and even leg bones is formed. According to the principle of dramatic human mechanics, firstly, the wrong negative force line on the inner side of the forefoot is dispersed to the middle sole, and the balance force is corrected from the sole. Secondly, the deformed foot bone and ankle joint are fixed, so as to achieve the correction effect. You can use a foot correction pad, which has a certain therapeutic effect on the internal character.
