Basketball is generally made for indoor play. So the material is different from the outdoor basketball. The indoor basketball is made with full-grain leather. These balls are very smooth to touch, and after a few uses, they become broken in and very more comfortable to grip. These leather basketballs are not suitable for outdoor use because the concrete surface will damage the leather and make it rough and ruin the ball's grip.
Some basketballs are made with synthetic leather or composite. These kinds of balls don't need to be broken like a regular leather ball. But honestly speaking, the quality of these balls is not good enough.
The outdoor basketball has a rubber surface so that it can absorb the rough surface of the concrete without losing the ball's grip. An outdoor basketball is good for the beginner because this type of ball is easy to control.
