When theCharlier shoe was first introduced, it was applied thefull length of the foot, but it was found that whenthinned by wear, the heels spread and led to injury ofthe opposite leg or to its being trodden off. Now the. Fig. 65.—a Tip laid on, not let down. Charlier is only applied like a tip round the front portioaof the surface of the foot, and it therefore partakes ofsome of the advantages I have credited to tips. It is avery light shoe and only requires small nails to fix itsecurely, but as the shoe is only the width of the wall,the nails have to be driven solely in the wall, and theirposition is open to the objection applying to all too finenailing. The disadvantages of the Charlier are its beinglet down too near the quick, its limited bearing, andits fine nail holes; the advantages are the lightness andthe freedom given to the back of the foot, both of whichare attainable with a narrow tip not let down.
