Abstract
Enhanced-grip foamed play balls, such as compressible, foamed play balls that are at least substantially formed from a foamed material and which include an exterior surface that is partially formed from the foamed material and partially formed from discrete regions of a different material that provides a grip-enhancing structure. In some embodiments, the grip-enhancing structure is formed from an elastomer. In some embodiments, the grip-enhancing structure has at least one of greater friction, greater density, greater weight, increased tackiness, decreased porosity, tread structure, projecting tread structure, and/or decreased compressibility than the foamed material. Methods for forming foamed play balls with grip-enhancing structures are also disclosed.
