The present invention presents a shoe or insole fitting navigation system including a set of foot sole pressure measuring sensors for measuring foot sole pressure distributions; a set of TV cameras for taking foot images; a processor; and a monitor screen. The present system acquires right and left foot sole pressure data, acquires right and left foot images, computes a foot sole gravity center position of each foot, computes an outer dimension of each foot, and determines bias in gravity center balance of each foot accurately based on the foot sole gravity center position of each foot and the outer dimension of each foot. In addition, the present system determines an abnormal foot symptom of each foot, and selects a shoe or insole of each foot based on the determined bias in gravity center balance and the determined foot symptom.
