    Abstract: A golf ball includes an inner core layer and an outer core layer. The inner core layer is formed from a first thermoplastic material and has a geometric center hardness that is greater than its surface hardness to define a first negative hardness gradient. The outer core layer is formed from a second thermoplastic material and has an inner surface hardness greater than its outer surface hardness to define a second negative hardness gradient. Inner and outer cover layers are disposed over the outer core layer. The negative hardness gradient of the inner core layer is about −1 to −5 Shore C. The negative hardness gradient of the outer core layer is at least −1 Shore C but less than −7 Shore C. A difference between the inner core layer surface hardness and the outer core layer inner surface hardness is at least −3 Shore C.

    Abstract: Golf ball incorporating a hollow innermost portion that is spherical or aspherical, and a shell layer that is at least partially non-continuous, having a plurality of hollow spaces therein that extend from the inner surface to an outer surface of the shell layer and are symmetrically spaced within the shell layer, wherein the non-continuous shell layer has a first hardness gradient from shell layer inner surface to outer surface of up to about 7 Shore C. An outer core layer has a second hardness gradient and is formed about the outer surface and within the plurality of hollow spaces. The outer core layer has a second inner surface having a second inner surface hardness that differs from the inner surface hardness. Thus, the second inner surface hardness and inner surface hardness may alternate symmetrically and circumferentially about the innermost hollow portion.

    Abstract: A golf ball comprising an inner core formed from a substantially homogenous composition such that the geometric center hardness is 56-80 Shore C and the outer surface hardness is 50-75 Shore C. An outer core layer has an outer surface having hardness of 85-98 Shore C and an inner surface hardness of 68-78 Shore C and being formed from a second homogenous rubber composition. A cover layer is disposed about the outer core layer. The hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient of +7 to +30 Shore C, and the hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient of −1 to −15 Shore C.
