This condition is similar to splay foot It consists in a loss of the arch of the foot Persons suffering in this way have a very low instep. The difficulty is occasioned by relaxation of the ligaments of the foot. The principal inconvenience occasioned is pain upon walking or standing long upon the feet.

The Treatment of Flat Foot

The arch of the foot should be supported by a properly constructed pad placed underneath it. The pad may be composed of cotton, rubber, or cork, placed beneath the instep in the shoe, or by means of adhesive strips and elastic tubes attached to the instep in such a way as to support it by traction.
