Who is there amongst human beings that does not prefer to wear an old pair of boots to a new pair—and why? Because the old pair has accommodated itself, by wear, to the ‘tread’ of the owner. The heel of a man’s foot is round on every side; yet his boot-maker will persist in making the heels of his boots with square edges; the consequence being that they wear more in one part than another. As all men have not the same natural tread, some will wear out the inside of the heel at the same time with the outside of the toe; whilst others will do exactly the contrary, or else wear them away in a different form from either. The time when they require mending is the time when they begin to feel comfortable; and the human shoemaker, like the equine one, proceeds to reinforce the parts that wear the quickest. The American Indian knows better than this. He fashions the exterior of the heel of the moccasin, as near as he can get it, to the shape of his own heel; and those who have worn moccasins for any length of time (as the writer has), positively ‘go lame’ when they have to put on a pair of civilised chaussures.
