Patent ID: 7325323

Claim:
A foot inclination angle measuring method, comprising the steps of: measuring a shape of a human foot in three dimensions; based on three-dimensional data on the measured shape of the foot, obtaining a two-dimensional cross section of the foot orienting in a front-rear direction, which includes a cross section of a heel of the foot; obtaining a central line which is a straight line connecting a point corresponding to a central line of the foot (foot axial line) at a height position of 2 to 6% of a foot length from a bottommost position in the two-dimensional cross-section to a central point of the two-dimensional cross-section in the right-left direction at a height position of 20 to 30% of the foot length from the bottommost position in the two-dimensional cross-section; and obtaining an angle of inward/outward inclination of the foot from an angle of inclination of the central line.
