The shoes suitable for patients with flat feet require the heel of the sole and the arch waist to be narrow, the upper to be tight, the inner half of the waist of the sole to be padded 2-3mm high, in order to restore the medial longitudinal arch of the foot and hold up the talus bone, the inner half of the heel to extend to the navicular bone and thicken 3-6mm compared to the outer half. In addition to wearing the above shoes, patients should also perform functional exercises, such as toe walking, toe flexion exercises, heel lifting and external rotation exercises, etc., and avoid prolonged standing. At the same time, nutrition should be strengthened, especially for children who have not yet fully developed, and the patient should not exercise strenuously in ordinary life, otherwise it is not easy to work.
