1. A golf ball having a plurality of dimples on a surface thereof, wherein at least a subset of the plurality of dimples has a cross-sectional dimple profile defined by x-y coordinates, wherein x=0 corresponds to a central axis of the cross-sectional dimple profile, y=−cd corresponds to a maximum depth of the cross-sectional dimple profile which is defined at the central axis, and the cross-sectional dimple profile is symmetrical about the central axis,
wherein a cross-sectional dimple profile is defined by a modified cycloid curve, and the modified cycloid curve is rotated about the central axis to define the cross-sectional dimple profile of the plurality of dimples,
wherein the modified cycloid curve is defined by:
