A golf ball includes an outer land surface and a plurality of dimples formed thereon. The dimples comprise structures of its surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. These structures may include sub-dimples arranged in various configurations on the dimple. The sub-dimples may have various sizes and shapes. The structures may also include radiating concave or convex arms emanating from the center or a location proximate the center of the dimple. The radiating arms may have various sizes and shapes and may protrude beyond the dimples. By improving the aerodynamic of the airflow over the dimpled surface of the golf ball, the outer land surface of the golf ball may remain robust to prevent premature wear and tear on the golf ball.
