THE PRESENT INVENTION DISCLOSES A FOOT ARCH CORRECTION CUSHION CAPABLE OF FINE-TUNING A CORRECTION AREA AND A CORRECTION METHOD THEREOF, PRIMARILY PROVIDING A MAIN ARCH SUPPORT PLATE (10) AND A PLURALITY OF FINE-TUNE CUSHIONS (20). THE MAIN SUPPORT PLATE (10) HAS A PLURALITY OF CUSHION POSITIONING PORTIONS (11) FORMED AT THE BOTTOM SURFACE OF THE MAIN SUPPORT PLATE (10) AS REQUIRED. THE FINE-TUNE CUSHIONS (20) PROVIDES A CUSHION EFFECT WITH DIFFERENT QUANTITIES OF FINE-TUNE CUSHIONS (20) APPLIED TO DIFFERENT POSITIONS ACCORDING TO THE HEIGHT OF THE FOOT ARCH AT DIFFERENT ARCH AREAS IN ORDER TO ELIMINATE ABNORMAL PRESSURES OF THE FOOT ARCH MORE SIMPLY, EASILY AND ACCURATELY AND FACILITATE ADJUSTMENTS FOR SUBSEQUENT PROGRESSIVE CORRECTIONS.
