A golf ball defining a spherical outer surface and a plurality of spaced-apart dimples formed in the surface. The dimples comprise a central raised portion and a surrounding depressed portion with the depressed portion having a lateral dimension along any straight line extending through the center of the central portion and from one outer edge to the opposite outer edge of the depressed portion. The maximum depth of the depressed portion is from 0.008 to 0.015 inches and the raised portion extends outwardly from the depressed portion to the position of the spherical outer surface. The maximum lateral dimension of the raised portion, measured parallel to the spherical outer surface, is less than one-half the minimum lateral dimension of the depressed portion. The total effective volume of the dimples comprising the cumulative volume occupied by the depressed portions of all dimples formed in said surface is greater than 0.021 cubic inches.
