Abstract
In a dimpled golf ball, the parameters of dimples are optimized to improve the aerodynamic performance of the ball and thus increase its flight distance. The dimples have a planar shape which is circular, and are of at least three types of mutually differing diameter. At least one of the types of dimples has a cross-sectional shape differing from that of the other types. One of the dimple types may have a cross-sectional shape defined by the union of at least two concave portions of differing slope.
