れる。The toe portion 10b of the armor cover 10 heated in the step (2) is placed on the shoe mold 20 with the back surface thereof facing downward before being cooled (that is, before being hardened), and the upper mold 22 Is lowered, and the toe covered portion 10b is sandwiched between the shoe mold 20 and the upper mold 22 and pressed with an appropriate pressure. As a result, the toe-covered toe portion 10b is curved and formed following the shoe mold 20. At the same time as this bending, the sheath 10 and the thermoplastic shape-retaining member 12 are cooled and hardened, so that the shape is also retained. At this time, the armor cover 10 and the thermoplastic shape-retaining member 12 are strongly joined by the joining force of the thermoplastic resin itself. Therefore, even if the upper die 22 is lifted after the curving and the cover 10 is removed from the shoe mold 20, the cover 10 does not try to return to a flat plate shape and is formed with good shape retention.
