Ball structures, such as basketballs, are formed to include regions with different and distinct tactile characteristics or “feel.” Such ball structures may include a cover member divided into plural panels that are separated by channels. The exterior surface of one or more of these panels may include regions having different textures. One region, which extends over a central portion of the panel, includes raised elements, such as raised ribs or other structures, that may extend at least 0.5 mm outward from a base surface of the cover member.
