  However, the golf shoe soles of Patent Documents 1 and 2 do not contribute to the improvement of the golf swing foam although good gripping force can be obtained.

  The present invention has been made in view of the above-described circumstances, and provides a sole for golf shoes capable of obtaining excellent gripping force and contributing to improvement of golf swing foam, and a golf shoe using the same. With the goal.

  In order to achieve the above object, the present inventors have focused on the fact that a so-called sway movement in which a weight flows outward in a golf swing form leads to a miss shot, and golf that can suppress this sway movement. A shoe sole was studied.

The present invention has been made as a result of the above research,
A front concave portion and a rear concave portion having a substantially arc-shaped cross section or a substantially elliptic arc section are formed on the inner portions of the forefoot / medium foot portion and the rear foot portion of the bottom surface of the sole body,
And the front convex part and the rear convex part are formed continuously or intermittently in a state continuous from the peripheral part at the peripheral part of the front concave part and the rear concave part,
A front anti-slip protrusion and a rear anti-slip protrusion are respectively disposed inside the front convex part and the rear convex part on the bottom surface of the sole body ,
The bottom surfaces of the front anti-slip protrusion and the rear anti-slip protrusion are located above the bottom surfaces of the front convex part and the rear convex part,
High hardness non-slip projections having higher hardness than the front convex portion and the rear convex portion are arranged on the outer portions of the front foot, middle foot portion and rear foot portion of the bottom surface of the sole body,
A sole for golf shoes is provided , wherein the front convex portion, the rear convex portion, and the positions of the bottom surfaces of the high hardness non-slip projections are equal .

  In the golf shoe sole of the present invention, when weight is applied to the front concave portion and the rear concave portion at the time of golf swing, particularly at the time of impact, both feet are substantially inward by being deformed so that the dome shape of the front concave portion and the rear concave portion is formed. It becomes a load, and as a result, sway can be prevented. Moreover, since a force is applied to the front convex portion and the rear convex portion so that they pierce the ground with the deformation, the local grip force is improved.

  Hereinafter, the present invention will be described in more detail. The sole body used in the present invention may have a single-layer structure or a multilayer structure such as a two-layer structure consisting of an outsole and a midsole. Examples of the material for the sole having a single-layer structure include foamed rubber, non-foamed rubber, thermoplastic urethane, and nylon, but are not limited thereto. As the material of the outsole in the two-layer structure sole, for example, foamed rubber, non-foamed rubber, thermoplastic urethane, nylon and the like can be used, and as the material of the midsole, for example, foamed rubber, foamed plastic Such an elastic foam can be used, but is not limited thereto.
