ABSTRACT:
A shoe of the high-upper type is formed by two slippers of leather or like material and of different size. One slipper is engaged within the other, a metal former is placed within the inner slipper, and the assembly is placed within a mold comprising two halves and a bottom mold block corresponding to the outsole and provided with an injection sprue. The plastic injected through the sprue passes through an injection orifice in the bottom slipper sole, spreads within the internal space between the two slipper soles so as to form the insole, then passes downwards through holes located in uniformly spaced relation in the bottom slipper sole and spreads between the bottom sole and the mold block so as to form the outsole which is thus intimately bonded to the insole. At the same time, the injected plastic flows upwards within the internal space between the two slippers so as to form the upper of the shoe.
