Indoor and outdoor basketballs can vary in their materials. An indoor basketball is made of full-grain leather, while an outdoor basketball is made of rubber.

Although indoor basketballs feel smooth to the touch, after a few uses, like baseball mitts, they tend to break down somewhat and become easier to grip.

You should not use leather basketballs as the concrete surface of the outdoor court may cause the leather to wear and become rough.

Some indoor basketballs are made of synthetic or composite leather. As for the qualities, they won’t break like regular leather balls. But their quality is low.

Outdoor basketballs, also known as “street” balls, have a rubber surface that allows the ball to absorb the rough surface of a concrete court without losing grip.

Rubber balls are also a good option for beginners as they are the most straightforward basketball to control.
