the patient walks wearing the insole of the varus force adjusting system of the invention, the pressure acquisition module 10 in the varus force adjusting system acquires pressure, and calculates the varus angle according to the acquired pressure. When the foot varus angle is smaller than or equal to the set angle threshold J, the control module 20 does not need to control the inflation/deflation module 30 to inflate the air bag, because the foot varus angle is smaller, and the foot varus angle belongs to the normal foot varus angle range, and correction is not needed; when the varus angle is larger than the set angle threshold value J, the valgus angle is larger than the normal valgus angle range, and the stress adjustment is needed to provide additional supporting force, at the moment, the target inflation time length is calculated according to the valgus angle, and the inflation and deflation module 30 is controlled according to the target inflation time length so as to inflate the air bags in the insoles, thereby realizing the adjustment of the pressure of a plurality of points on the soles of the feet and further improving the abnormal stress of the feet of the patients.
