Abstract
The invention provides a method of measuring and identifying foot arch type according to footprint data. The method includes: obtaining a static standing footprint having a foot contour including lateral and medial contours; obtaining a lateral ball and lateral heel tangent points of the footprint, and a medial ball and a medial heel tangent point of the footprint; obtaining a ball and a heel mid-point; obtaining a foot center axial line and a foot perpendicular bisector; obtaining the length of a foot width Lf as the length of the foot perpendicular bisector, and the width a foot arch La; and calculating a foot type index FTI by dividing the width of the foot arch La by the length of the foot width Lf (FTI=La/Lf), and identifying a foot arch type of the footprint by the foot type index FTI.
