Golf shoes comprise a shoe 1 for a pivoting foot and a shoe 3 for a kicking foot. Outsoles of the shoe 1 for a pivoting foot and the shoe 3 for a kicking foot are formed of rubber or synthetic resin. A projection 7 is formed on a bottom surface of the shoe 3 for a pivoting foot. The projection 7 includes an almost semicircular bottom surface 11, a toe side wall 13 to be a curved surface and a heel side wall 15 to be a rectangular plane. The toe side wall 13 has a convex shape in a direction of a toe. A projection 19 is formed on a bottom surface of the shoe 3 for a kicking foot. The projection 19 includes an almost semicircular bottom surface 22, a heel sidewall 23 to be a curved surface and a toe side wall 25 to be a rectangular plane. The heel side wall 23 has a convex shape in a direction of a heel. If a golf player wears the golf shoes, slip can be prevented during a swing.
Golf shoes comprising a pair of shoes used by a golfer having a pivoting foot and a kicking foot having a different arrangement of projections on the sole of each shoe, wherein the projections on each shoe are convex on one side and not convex on the other side, with the convexity being towards the toe on the shoe worn by the pivoting foot, and towards the heel on the other shoe worn by the kicking foot.

The present invention relates to golf shoes, and more particularly to an improvement in a pattern of a bottom surface of golf shoes.
2. Description of the Related Art
FIG. 1 is a bottom view showing golf shoes according to an embodiment of the present invention,
FIG. 2 is an enlarged perspective view showing a projection of a shoe for a pivoting foot of the golf shoes illustrated in FIG. 1,
FIG. 3 is a sectional perspective view taken along the line III—III in FIG. 2,
The present invention will be described below in detail based on a preferred embodiment with reference to the drawings. The drawings to be used in the following description show golf shoes for right-handed golf players. Accordingly, a left foot wears a shoe for a pivoting foot and a right foot wears a shoe for a kicking foot. Golf shoes for left-handed golf players have shapes obtained by transversely inverting the shape shown in the following drawings
FIG. 1(a) is a bottom view showing a shoe 1 for a pivoting foot of golf shoes according to an embodiment of the present invention, and FIG. 1(b) is a bottom view showing a shoe 3 for a kicking foot of the golf shoes. The golf shoes comprise the same upper portion and insole as those of ordinary golf shoes, which is not shown. In FIGS. 1(a) and 1(b), a right direction is set to the front side in a hitting direction, a left direction is set to the rear side in the hitting direction, an upward direction is set to a direction of a toe, and a downward direction is set to a direction of a heel.
The shoe 1 for a pivoting foot has a outsole body 5. A large number of projections 7 are formed on the bottom surface of the outsole body 5. A portion on the bottom surface other than the projections 7 is a flat portion 9. The shoe outsole body 5 and the projections 7 are formed integrally. The outsole body 5 and the projections 7 are formed of a composition containing rubber or synthetic resin as a principal component.
