“ If you do not fix feet by this rule, the sensitive portion of the foot will often prevent you from lowering it enough to level up matters with opposite side, and the sensitive parts of the foot that will prevent you from doing this will be the outside of a front foot and the inside of a hind foot. This is the main reason why so many floormen in shops all over the country cut the inside of front feet too low for the outside, and leave the inside of the hind feet too high for the outside of same. ”
