5~12 years old is a critical period for skeletal muscle development.
Functional flat feet can deform the arch and can not effectively absorb the pressure of the sole, resulting in uneven force in the lower limbs.
In the future, it may cause hunchback, X-leg, thoracic tilt and pelvic front. The FOOTDISC children's insole provides arch support and shock absorbers. The lightweight material is wicked and breathable, making the gait tend to normal arch and leg shape to improve poor gait.
