What's the difference between an indoor, outdoor, and indoor/outdoor basketball?

Across the reviewers we read, composite-leather indoor balls (like the Wilson Evolution) feel softest and grippiest but wear down fast on concrete, while rubber balls survive rough outdoor courts at the cost of feel. Specialist-subreddit consensus is that 'indoor/outdoor' composite balls actually lean better for indoor or occasional outdoor use, and that a dedicated rubber ball is the durable choice for asphalt and park courts.
