Title: Instep and shoe with it
Inventor: YOSHITOMI MASAHIRO
IPC: A43B23/02
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To eliminate a defective appearance caused by contracting wrinkles by cutting the toe part of a tip member and butting a tip narrowing member along this shape to sew so as to tilt the tip narrowing member downward. SOLUTION: Concerning the instep, the toe part of the tip member 1 is cut and the tip narrowing member 3 is butted along the shape of this notch part and sewn to tilt the tip narrowing member 3 downward. Thus, the shape becomes easy to fit to a last to reduce contracting wrinkles to make it difficult to generate detective appearance caused by contracting upward. In addition, by covering and hiding a tip narrowing part sewing position 4 with a turning tape or a tip protector, the instep is not different at all in its appearance. It is desirable that the position 4 is higher than the lower surface of the last when being hung in the last at the time of molding the shoe and that the shape of the part 3 is nearly crescent along the carve of the toe.  A level difference is eliminated by butting the tip narrowing part against the sewing position 4 of the tip part and zigzag-switching them and the foot never touch it.
