The foot projected contours from the right and left feet were taken with 149 male and 177 female Japanese adults. The samples were classified using two methods, especially focussing on the shapes of the forepart in the feet. One method is a classification using the foot length I and the foot length II. Comparing the foot length between I and II, the feet were divided into three types. The other method is a classification using the angles of the toe 1 and the toe 5. The feet were divided into four types, depending on whether the toe 1 was outward to the toe 5 or not, and whether the toe 5 was inward to the toe 1 or not.
The results disclosed that the occurrence in type of A. 15 denoting the longer foot length I, the outward toe 1 to the toe 5 and the inward toe 5 to the toe 1, was the most frequent, amounting to ca. 44% in males and ca. 45% in females. It was, therefore, concluded that the shoes last fitting this type of A · 15 should be industrially produced most frequently.
