What do the words inside and outside mean?

The main reason for splayed feet is that when I was a child, I learned to walk and stand too early, and my legs were weak, so it was difficult to keep my balance. Therefore, my toes naturally separated to the left and right to expand the area of my feet, increase my stability and prevent me from falling, and gradually formed a habit. According to your condition, I suggest that you use orthopedic insoles to correct insoles, mainly to support the arch when walking. Correcting walking can readjust the arrangement of foot bones by changing the incorrect negative force point of the foot. Long-term orthopedics can make the arrangement of foot bones reach the best state, especially for common foot diseases such as flat foot, hallux valgus, heel valgus, horizontal arch collapse, internal and external splays, and bone diseases such as O-leg, X-recession and cervical vertebra.
