This year, the ball shouldn’t have that kind of impact on which team wins the World Cup. In wind tunnel tests, Goff found that Telstar 18 has a very similar aerodynamic profile to the 2014 Brazuca ball, which flew without the wobbles of the Jabulani. The Jabulani was the first ball to have six seams and despite having a roughened surface, it was too smooth, says Goff. When the Brazuca was released, it had 68 percent more seams than the Jabulani to help change the airflow around the ball. The Telstar 18 is even more improved. Instead of transitioning to laminar flow in the middle of free kicks, Goff found that the Telstar 18 goes through its drag crisis at a lower speed of 38 miles an hour.
When it comes to the training soccer ball, it can be purchased at a much-reduced price as compared to the actual match-ball. Incorporating inferior quality materials in its construction, this is an ideal equipment for the sake of training. So if you’re looking for any such ball to sharpen your skills, have a look at the Adidas Champion’s League Finale Capitano Soccer Ball.
This ball has a TPU cover that we wouldn’t describe as “highly durable” for rough play. Although it handles indoor turf, it won’t handle concrete, gravel, or court-based play like you have with futsal. This ball prefers to have a natural or artificial grass surface and that is about it. If you happen to impact a tree, run the ball on concrete, or have it bounce on a gravel driveway, the outer cover does tend to get scratched up pretty rapidly. The butyl bladder is of a higher quality than other balls at this price point, allowing the ball to hold its inflation pressure with an impressive amount of consistency.
