1, lining, of course, you can't cut the basketball into it, but you can try it by patting it. The lined basketball falls vertically on the chest and the height of each rebound is the same.
2, winding, good winding can make the bounce of basketball have a sense of texture, the ball flies and rotates stably and accurately when shooting, and it will make the ball very firm and not easy to deform. The judgment method is to repeatedly press the basketball with both hands. If you feel solid and have a strong rebound, it proves that winding is better.
3, epidermis, a good epidermis should have the advantages of non-slip, wear resistance, sweat absorption and so on. Test anti-slip, you can directly feel whether the ball touches your hand. Wear resistance test, you can scrape the basketball surface with your nails. If there are obvious scratches, it means that the skin is not very wear-resistant. As for sweat absorption, wipe the basketball surface with a wet cloth. If it dries in a short time, it proves that sweat absorption is better.
4, feel, I feel that this thing is not easy to say, experts can feel good or bad as soon as they hold it in their hands. If you have no experience in this field, please pay more attention to compare the weight of basketball and whether the lines are consistent.
