Using a wind tunnel, Goff has researched the flight properties of the Telstar 18, drawing its drag curve to discover where the ball might dip and swerve in the air, similar to the knuckleball free kicks favored by Cristiano Ronaldo “Even if aerodynamically the Telstar 18 isn’t that different from the Brazuca, it’s still going to wobble a little bit differently because the panel shapes are different,” Goff says.
Controlling the game is everything. From touch, shape, and movement, to flight of the ball, the construction of your soccer ball can impact how well you command the pitch. Competitive soccer players usually have different types of soccer balls for training, match day or just to kick around. See the options below for choosing the right adidas soccer ball for your favorite type of play.
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.
2010 Jabulani Adidas This ball has 8 panels. A special variant was used for the final match, the gold Jo'bulani (picture on the left), which was named after "Jo'burg", a standard South African nickname for Johannesburg, site of the final game. The ball was notable for the controversy it attracted, with players and fans contending that its aerodynamics were unusually unpredictable. 
This ball also comes in sizes 5, 4, and 3 and ships at one pound exactly, and it does not appear to come inflated. This soccer ball ships within the US and is not eligible for international shipping. For the low price and quality of this ball, it is totally worth the value because the exact ball that the pros use is around $100, and this pro soccer ball replica is a fraction of the price.

The machine stitching is strong and offers a fairly long lasting performance.
