SHOES CONCAVE INJURIOUS.

of an inch, more or less according to what the foot will 

 bear, and put on again. Now, drive the nails again, each 

 a little at each time until driven home, and clinch firmly. 

 It is seen that the shoe must now exert an outward pressure 

 upon the heels equal to the increased breadth of the shoe. 

 Keep the foot reasonably soft. In a few days or a week the 

 clinches can be carefully drawn, the nails pulled out, the 

 shoe made wider and nailed as before, which can be 

 repeated so long as the nails will hold well. 



A simpler method is that of the convex shoe, (cut 17.) 

 The foot is prepared as before, with the difference of not 

 cutting away the bearing surface so much at the heels. The 

 shoe, instead of having the bearing surface level, should be 

 made convex, the outer edge from an eighth to one-fourth, 

 or even more, of an inch lower than the inner edge, running 

 out at the toe. This surface should be filed down carefully, 

 and so fitted to the foot that the heels will rest on these in- 

 clined surfaces, the shoe being a little wider than the heels, 



and nail on. Now there 

 is a continued slipping 

 outward of the heels when 

 weight is thrown upon the 

 foot. Remember one 

 point here. Do not com- 

 mit the error of cutting 

 down the heels very close. 

 You must have horn 

 enough to keep the shoe 

 from coming in contact 

 with the sole. If it does, 

 the inner edge pressing 

 upon the sole forms a 

 shoulder which will not 

 only prevent expansion, 

 but bring pressure upon 

 the sole, bruising it, and 

 thus be the cause of injury and lameness. 



The third, is that of Tyrrel's patent shoe, (cut 18.) By 

 this shoe, if properly fitted and applied, the foot can be 

 expanded as little or as much as may be desired. It will 

 also enable expanding one or both heels as may be 

 desired, and is the best form of shoe I have seen 



( No. 17.) Convex Shoe for the cure of 

 Contraction.
