PURPOSE: To strongly connect an upper and a middle bottom without drifting and displacing the hanging position by forming multiple holes with a proper diameter on the hanging margin of a toe lining serving as the junction face with the side face of a middle bottom rib.

CONSTITUTION: The hanging margin 3a of a toe lining 3 is stuck to the side face of the rising section 5a of a middle bottom rib by an adhesive like in the past. Multiple holes 10 formed by punching or the like are provided on the toe lining 3 at the position serving as this junction face. Part of an adhesive layer coated on this junction face bites into the holes 10 and is solidified, thus the toe lining 3 and the rising section 5a of the middle bottom rib are firmly connected. The excess hanging margin of an upper 1 is matched with the lower end edge of the rising section 5a, they are sewn after the trimming is removed. The hanging position of the toe lining is not drifted, it is completely connected to a middle bottom, no peeling off or the like occurs on an adhesion section.
