Indoor and outdoor basketballs are both designed to be used in different environments. Indoor basketballs are designed to be used in a controlled environment, such as a gymnasium or basketball court. They are typically made of leather or composite materials and have a softer feel than outdoor basketballs. Outdoor basketballs are designed to be used in outdoor environments, such as a driveway or playground. They are typically made of rubber and have a harder feel than indoor basketballs. Both types of basketballs are designed to provide a great playing experience, but the type of ball used should be chosen based on the environment in which it will be used.
