Abstract: A sports ball comprising an inner core with a plurality of nubs on its exterior surface, and an outer shell comprising two hemispheres that surround the inner core such that the plurality of nubs contact the inner surfaces of the outer shell's inner cavity. The outer core can comprise a cross-linked closed-cell foam such that the sports ball can be more durable and softer than conventional balls normally used for the same sport.

Abstract: A thumb and finger insert for a bowling ball including a barrel having a thumb or finger hole for insertion of either a human thumb or finger and capable of facilitating a properly timed release of a bowling ball and of adapting to digit swelling during play. The barrel has a complete annular portion and a partial annular portion, the latter forming a gap into which a flexible tab is disposed. The flexible tab is connected to the partial annular portion with one or more flexible members and includes an underside that engages the dorsal side of a user's thumb or finger, wherein the flexible members will flex so as to allow said flexible tab to flex outwardly when pressure is exerted against the underside of the flexible tab.
