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.
Over time, many soccer balls tend to go out-of-round, especially if they are well-used. The Glider is designed to maintain its shape without losing air thanks to the firmness and consistency of the butyl bladder. Under regular use, we found that the air pressure was consistent enough that we didn’t need to add more air to the ball. If you play in organized soccer, then having consistency from the practice ball to the game ball is very important for skill development. The machine-stitched panels offer that experience for most players, even though the ball has the standard panel design.
Another type of soccer ball that some players may find to be useful is the indoor soccer ball. Indoor balls are designed to have less bounce and rebound to them, making it possible to control the ball on a tighter court or field. The cover of an indoor ball is also the strongest of any category, so it can withstand play on turn, hard court surfaces, and impacts with walls.

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. 
Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.
