If your child’s feet are crooked, it is very likely that your child is suffering from flat-footedness, which is also known as flat feet. Especially in infants and young children before the age of seven, many of them will suffer from the symptom of inward-facing feet. This is mainly due to the fact that the growth and development of the foot arch is still incomplete at this age, and once the foot arch is not formed, it is easy to cause the symptoms of flat feet. If the child is over 7 years old, or has passed puberty, it can be determined that the foot is caused by clubfoot or flat feet, and should be adjusted before the growth and development is complete. If the foot is just a habitual inward curvature and there is no flatfoot, the foot can be adjusted by wearing orthopedic shoes.
