There remains still one other defect to be noticed—that of treading upon the side of the foot. This is a very common fault, and seems to be a habit often acquired quite early. The feet appear to leave the old, upright way of getting through the world, and take a sidewise deviation. Having commenced losing their uprightness when young, they, unless speedily helped, seldom recover it entirely afterward. The individual who possesses such unfortunate _inclinations_ never has the satisfaction of knowing what it is to stand up in _perfect rectitude_. Whether the physical leaning of the feet has any tendency to create a moral one-sidedness may be considered an open question. It is hardly safe to say that it does _not_, when we know that the whole carriage, attitude, and dress of the individual has an effect upon the condition of the mind. But leaving that to be settled as it may, we must see what can be done to straighten the feet up to their natural position. Feet that tread upon the _inside_ are, many of them, _flattened_ somewhat at the same time. This latter fault may come from any of the influences previously pointed out, or from a natural weakness of the muscles and ligaments of the ankle, which condition frequently exists in children. When this is the case, the arch of the foot being turned, the weight of the body is improperly directed upon it—that is, the arch bears this weight slightly upon one side instead of directly _over_ itself. This tends to break it down and make the foot flat. The flatness, if already existing, may tend to throw the foot still more toward the side. Either way, the first thing to be done is to counteract the flatness by a sufficiently long heel under the shoe, to support the arch. The shoe should also be made upon a flat-bottomed last, and one that will compel it to draw tight along the sides and ankle. Another requisite is that the counter shall be very _stiff_ on the inside, while on the opposite side it should be _weak_. It should also be high as well as firm, sometimes _very_ high, as when the ankle requires very much support. When, however, it reaches so high as to touch the prominences of the joint, it must be carefully thinned on the edge to prevent chafing the bone. If the weakness is but slight, the principal part of the stiffness may be near the bottom, where a good deal of it will do no harm.
