Used Spalding Basketball Adult Indoor

Spalding NBA Zi/O Indoor/Outdoor Basketball – Official Size 7 (29.5"), Adult

The Spalding NBA Zi/O® is a premium composite-leather basketball designed primarily for indoor play but durable enough for light outdoor use. It has been one of the most popular gym and rec-league balls for over two decades thanks to its soft, tacky feel right out of the box, excellent grip, and consistent bounce.

Widely used in high-school gyms, college practices, and adult leagues across North America, the Zi/O series delivers a true intermediate step between Spalding’s top-end TF-series genuine leather balls and basic rubber outdoor models.

Key Features

• Zi/O Composite Leather Cover – exclusive Spalding material that breaks in quickly and provides superior grip and control (softer and tackier than standard composite balls).
• Deep Channel Design – wider, deeper pebbling for fingertip control and shooting consistency.
• Foam-Backed Construction – extra layer under the cover gives the ball a cushioned, game-ready feel from day one.
• Butyl Bladder – excellent air retention; stays inflated longer than cheaper balls.
• NBA Branding – official NBA logo and Spalding branding (often with commissioner’s signature).
• Rotationally Molded Carcass – perfectly balanced for true flight and bounce.
