PROBLEM TO BE SOLVED: To provide a tennis shoe that excels in antislip performance.SOLUTION: The outsole of a tennis shoe includes a base and a large number of first projections 24 which each have a striped appearance and a zigzag. The first projections 24 are composed of a plurality of first elements 30 and a plurality of second elements 32. The angle α in the direction of a normal L6 of the first element 30 relative to the line segment L1 is not less than 70° and not more than 135°. The angle β in the direction of a normal L7 of the second element 32 relative to the line segment L1 is not less than 70° and not more than 135°. The difference (β-α) is not less than 20° and not more than 60°. The first projections 24 exist in the region of the sole in which, in the length direction, a distance from the end of the toe side is not less than 25% and not more than 40% of the length and in which, in the width direction, a distance from the end of the inside is not less than 10% and not more than 45% of the width.SELECTED DRAWING: Figure 4 |
