Abstract
A method of measuring the height of a foot arch precisely and easily using two essential heights of the foot arch is disclosed. In the method, a foot cast is primarily cast by pouring plaster into a foot mold. Thereafter, a first intersecting point and a second intersecting point are determined. The first intersecting point is determined by making a first line and a third line intersect. The second intersecting point is determined by making a second line and the third line intersect. The first line is a straight line extending from the center of the second toe to the center of the heel end. The second line is a straight line extending from the center of the big toe to a point spaced apart inwardly from the center of the heel end by 1/8 of the total distance of the heel end. The third line is a center line of the transverse arch of the foot. Finally, a first height and a second height are measured while the foot pattern is set in an upright position. The first height is defined between a flat base level and the first intersecting point, while the second height is defined between the base level and the second intersecting point.
