Patent ID: 8597209

Claim:
A method of correcting and balancing a user's foot, comprising: obtaining an initial footprint of the user's foot, by placing the user's foot on a resilient fabric sheet containing ink so as to make an imprint the initial footprint of the user's foot on a sheet of paper; analyzing shape and darkness of the ink on the paper of the initial footprint to obtain initial information as to a location where the user's foot has foot imbalance; and selecting one or more appropriate balancing pad(s) from a set of balancing pads and applying the same to a sole unit of a foot correcting and balancing shoe assembly at the location where the user's foot has the foot imbalance; wherein the analyzing of the shape and darkness of the ink on the paper with the initial footprint of the user's foot includes: drawing a contour line around a periphery of the initial footprint; drawing a transverse reference line that passes through a rear end of the initial footprint, a first longitudinal reference line that passes centrally through the index toe of the initial footprint, and a second longitudinal reference line that passes through an inner lateral side of the initial footprint that is proximate to the big toe of the initial footprint and that is parallel to the first longitudinal reference line, the first and second longitudinal reference lines being perpendicular to the transverse reference line; analyzing areas of the left and right sides of the first longitudinal reference line to determine a tilting direction of the initial footprint, analyzing the darkness of the ink to determine the distribution of pressure on the foot of the initial footprint; and analyzing an inclination angle of the big toe relative to the second longitudinal reference line to determine an angle of deviation of the big toe.
