Athletic shoe |
摘要 |
An athletic shoe has a sole composed of an inner layer and an outer layer that comes into contact with the ground surface. In the athletic shoe, a plurality of downward projecting projections are formed on the lower surface of the outer layer as parts of the outer layer, and a ring-shaped flange portion is formed as a part of the outer layer to surround the corresponding projection. The ring-shaped flange portion slants upward from its outer edge toward the inner edge. When a downward pressure greater than a predetermined value acts onto a portion where the projection and the corresponding flange portion are formed, the flange deforms in order to move the projection downward. In another athletic shoe, a plurality of projections is formed on the outer surface of a sole, and a depression is formed in the outer surface of the sole in the vicinity of each of the projections. The athletic shoe is excellent in terms of performance in gripping a soft ground surface such as a lawn surface and the easiness of walking on hard surfaces such as a paved path or a floor.
