 of shoes, whilst avoiding any increase of weight. 

 Without calkins, wear is more evenly distributed, and 

 the toe is not worn away disproportionately to the rest 

 of the shoe.

A calkin throws the leg and foot to some extent out 

 of their proper position. A very high calkin is not only 

 objectionable, it is unnecessary. Not much prominence 

 is required to afford a catch or stop. Excessive height 

 is usually given to meet wear, and this can be obtained
