It is more difficult to judge the quality of the rubber compound than the pattern of traction. If you opt for softer rubber, it will be ideal for indoor but for outdoor use, it will be a wrong pick since it collects a lot of dirt. Meanwhile, if you opt for hard one, it will give you durability but it will not offer the same grip in pristine hardwood terrain. So, if you have choices between color-ways with transparent and robust outsole, you must opt for the second one. Because a robust outsole will not look nice but it will give better performance that you expect from the shoes.
Material speaks of nothing but the durability of the product. There are many shoes that used to be made up of leather primarily. But now times got changed. In the modern times, the brands make basketball shoes with mixed materials so that they can perfect the shoes. So, you can take the one that comes with a combo of synthetic or textile upper with leather materials.
