At the time of this engagement, it is possible to securely engage the ridge 21a to the depth of the bottom of the concave groove 13a by pressing with a fingertip along the circumferential direction of the outer peripheral surface of the peripheral edge 21 ( 7 and 7A).

  As described above, according to the present embodiment, in order to attach the toe protecting portion 2 to the toe portion of the shoe 1, the protrusion 21 a of the toe protecting portion 2 may be engaged with the concave groove 13 a of the toe guard 13. Occasionally, no nails or rivets are required, so they can be easily attached. In addition, since a driving margin for nailing or riveting is not required on the bottom side of the outsole, the spike 15 can be disposed also on the tip end side of the outsole 12 (see FIGS. 3 to 7). The degree of freedom in the layout of the spikes 15 can be improved, and the support stability of the toe portion at the time of grounding can be improved. In particular, FIG. 3 clearly shows that the spikes 15 can also be arranged in the area of the conventional nail driving margin 22 (see dashed line). Furthermore, since the toe protection part 2 can be removed from the toe part of the shoe 1, it can be replaced when the toe protection part 2 is worn.

  Further, according to the present embodiment, the toe protection portion 2 is provided on the shoe via the protruding ridge portion 21a protruding from the inner peripheral surface of the peripheral edge portion 21 toward the inner peripheral side and the concave groove 13a of the toe guard 13 engaging with the ridge portion 21a. Since it is attached to the toe portion of the shoe 1, even if a vertical shearing force acts on the toe portion of the shoe 1 during exercise such as a baseball throwing operation, such a shearing force is applied to the ridge 21a and the groove. 13a, the toe protector 2 is not displaced in the vertical direction by the action of the shearing force, so that a strong engagement state can be realized. When the ridge 21a is engaged with the groove 13a, the inner peripheral surface (including the ridge 21a) of the peripheral portion 21 of the toe protecting portion 2 and the outer peripheral surface (including the groove 13a) of the toe guard 13 are provided. By applying an adhesive beforehand, a stronger engagement state can be ensured.
