outer margin, and running only partially through the inner 
half of the web (see Fig. 76). 
According as the contraction is confined to the inner or 
outer heel, the saw-cuts, one or two in number, are placed 
to the inner or outer side of the toe-clip. When the con- 
traction is bilateral, the saw-cuts, one or more in number, 
are placed on each side of the toe-clip. 
(d) Broué’s.—This is one of the forms of so-called ‘ slipper ’ 
shoes (see Fig. 77). We have already indicated that the 
shape of the bearing surface of the ordinary shoe—by its 
‘ seating ’ or sloping from outside to inside—is sometimes a

cause of contraction. In the ‘slipper ’ of Broué this bearing 
is reversed, and the slope is from inside to outside. In the 
original form of this shoe the slope to the outside was con- 
tinued completely round the shoe. Experience taught that 
the strain this enforced upon the junction of the wall with the 
sole was injurious, and;that the ‘ reversed seating,’ if we may 
so term it, was best confined to the hinder portions of the 
shoe’s branches. 
The amount of slope should not be excessive. If it is, 
too rapid and too forcible an expansion takes place, and 
pain and severe lameness results. Dollar gives the requisite
