Abstract: A golf ball with a plurality of recessed dimples having a shape in accordance with a certain mathematical ratio on the surface thereof is disclosed. The value of the spatial volume of each dimple below a plane defined by an edge of the dimple divided by the volume of a cylinder, wherein the bottom of the cylinder is defined by the plane and the height is determined by the maximum depth of the dimple from the plane, is within the range of 0.35 to 0.43. The dimples having such a shape represent at least 90 percent of the total number of dimples on the golf ball. The maximum diameter of the dimple can be within the range of 2 to 4 mm and the maximum depth of the dimple can be within the range of 0.1 to 0.4 mm. This configuration results in a golf ball having an increased carry.

Abstract: A golf ball having a large carry having a core, a rubber thread layer and a cover layer, in which the rubber thread is composed of a rubber composition consisting essentially of 100 parts by weight of natural rubber and/or cis-1,4-polyisoprene and 2-20 parts by weight of carbon black.
