The difference in the general character; sticks of individual men's feet and between different individuals is strikingly apparent when measuring and fitting is practiced. The points of difference are not merely width and length but involve multiple minor parts which together form a proposition of which some cognizance should always be taken. In discussing the similarity of people's features we always say there is " something " about him or her that is familiar but .cannot definitely say. We cannot definitely say because our casual inspection is not complete enough. Correspondingly there is that "something" about the feet which collectively make a great difference and presents obstacles which must be overcome if accurate measuring and fitting are to be practiced. These differences between the feet may be stated to consist essentially in the posture of the feet causing the ankle joint to deviate inwards or outwards; the slope of the toes backward from the great toe presenting, according to the

length of the toes either a pointed or square front; one may be thin, bony and devoid of extensive muscular development while the other may be fat, well padded in the heel, sole and around the joints and very much thicker through any given part than the other. Again the heights of the arches both anterior and longitudinal differ, and there may be a great difference in the distance from the back of the heel bone to the metatarsals in one individual's feet and the distance between the same points in another's. The distance mentioned—from the back of the heel bone to the metatarsals—is of great importance in fitting as it fixes the location of the primary and secondary ball-points.

In investigations conducted in the Army Concentration Camps, it was found that in 4o per cent. of the enlisted men's feet the left foot was larger than the right. In some cases, this difference equaled two full sizes. Such findings as this suggest food for thought. However, even with this great variation in some cases, there will not result from any mistakes in fitting either foot too short, as the Resco Marine Corps Fitting System requires that each foot shall be measured and the larger foot serves as the index of size. The correctly fitted shoe must allow all parts of the foot to function unrestricted and unhampered by any impediments. The parts of the foot which are important to consider in regard to the degree of functionality when a shoe is fitted are the following

1. The anterior and longitudinal arches,

2. Expansion of the foot sidewise and lengthwise.

3. The "Tripod"—the principal points of locomotion and weight, bearing—must be considered and shoes fitted so that it is allowed to spread apart and afford the maximum bearing surface.
