Embodiment 1

[0059] A rubber composition using polybutadiene as a base rubber is injected into a mold. This rubber composition is pressurized and heated to form an outsole having a base and protrusions. The pair of golf shoes of Example 1 was obtained by combining the outer sole, upper, midsole, and inner sole. The pair of golf shoes is composed of a golf shoe for the right foot and a golf shoe for the left foot. In each golf shoe, there are 60 protrusions in the region Z. The area s2 of the ground plane of each protrusion is 4.5mm 2 . In this golf shoe, the area S of the zone Z is 3300mm 2 , the area S1 is 3240mm 2 , the area S2 is 270mm 2 . Therefore, the proportion P1 is 98%, and the proportion P2 is 8%. The hardness of the base and raised Oscar A is 75.

Embodiment 2-4 and comparative example 1

[0061] The area s2 of the ground contact surface was made as shown in Table 1 below, and the others were the same as in Example 1 to obtain golf shoes of Examples 2-4 and Comparative Example 1.

Embodiment 5-7 and comparative example 2

[0063] The number of protrusions was made as shown in Table 2 below, and the others were the same as in Example 1 to obtain golf shoes of Examples 5-7 and Comparative Example 2.

Abstract

A gold shoe has an outer shoe sole (10), wherein the outer shoe sole has a substrate (16) and a plurality of protuberances (18) protruding downwards from a bottom surface of the substrate. The distance from an end (12) of a shoe head side in the length direction at the bottom surface of the substrate (16) is 10%-40% of the length (L), an area (Z) of an outer side is formed in a width direction compared to the longest line (L1) which can be drawn at the bottom surface, the ratio (Pl) between the area (S1) of the portion of the bottom surface covered by the protuberances (18) and the area (S) of the bottom surface is more than 20%. Within the area (Z), there are more than ten protuberances (18) of which the area (S2) of grounding surfaces is more than 1 mm<2> and lower than 36 mm<2>. The ratio (P2) between the total area (S2) of the grounding surfaces of the all protuberances (18) of the area (Z) and the area (S1) is lower than 45%. The hardness of the Asker A of the protuberances is more than 50.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2012-78512 filed on March 30, 2012. The entire content of this Japanese application is hereby incorporated by reference. technical field [0002] The present invention relates to a golf shoe. Specifically, the present invention relates to an improvement of an outer sole of a golf shoe. Background technique [0003] When a golfer hits a golf ball, the line connecting the left and right toes is substantially parallel to the target direction and performs an impact preparatory action. In the pre-impact movement of the right-handed golfer, the left foot is positioned in front of the target direction, and the right foot is positioned behind the target direction. In the preparation for impact, the head of the golf club is located near the golf ball. From this state, the golfer starts a backswing, swings the club head backward, and then swings upward. The highest position to which the club head is s...
