However, in Goff’s wind tests, he and his team noticed that the Telstar 18 had a little more resistance at high speeds, and predict that the ball will go about eight to nine percent less distance down the pitch on long kicks. This means that Manuel Neuer, the goalkeeper for Germany who was considered to be the x-factor that brought Germany the win in 2014, might not have quite as much of an impact clearing balls from the goal this time around Goff says. “You’d see him just kicking the ball way, way down the pitch, and [this World Cup] you might notice that some of those kicks aren’t quite as long as before,” Goff says.
Good soccer games begin and end with your soccer ball! Without the right one, all the slick moves, all the training and team work are not going to make up for points lost by not having the right soccer ball. By understanding the differences between balls, how to select the right ball for you, and how to make the most of your soccer ball can mean all the difference in your game.

This soccer ball offers the traditional look and design of the pentagon panels in alternating black and white, allowing players to learn foot placement for a good bend. There is enough weight to the ball to allow for accurate crossing and passing drills, while enough rebound exists for dribbling and shooting drills. If you take your game seriously and you want to improve at home, this is one of the best and most affordable options that you’ll want to consider. Multiple sizes are available with this traditional design.
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. 
If you’re working on headers, then your forehead won’t feel like it is being repetitively hit with a meat tenderizer thanks to the design of this ball. That soft touch also translates to a reasonably authentic movement when working on crosses or shots. There is a reasonable bend that allows players to wrap a leading ball around a defensive line, curve a shot around a wall, or work on accurate passing. Control skills off of the chest or knee feel close to authentic as well.
Despite the similarities with the Brazuca, the few differences between this ball and what players have gotten used to over the last four years will have an impact on play, says Firoz Alam, an aerodynamics engineer at the Royal Melbourne Institute of Technology in Australia, who has also performed wind tunnel tests on the Telstar 18. “When the player is making a short pass, they have to push a little harder, because at less then 60 kilometers per hour [or 37 miles per hour]it has more flight resistance than the Brazuca,” says Alam. The mid-range passes and corner kicks that gave the Jabulani so much trouble have been resolved. Compared to the Brazuca, the Telstar 18 is also more aerodynamically efficient in the 40-50 mile an hour range, so Alam says players will actually have to kick a little softer or they’re likely to overshoot. Over 55 miles an hour the two balls will feel very similar.
Adidas designs every World Cup ball, and on top of being a big seller for them, engineers at the company are constantly a little closer to the perfect ball, Goff says. The ideal soccer ball is a pimple-covered, perfect sphere, its surface just subtly textured enough to keep the airflow around the ball slightly turbulent. Unintuitive as this might sound, the ridges and pimples on the ball make it more aerodynamic, helping the ball to fly through the air more stably.
Built for durability, recreation balls are made of soft synthetic materials for play on nearly any field. Typically, these balls are slightly heavier for beginner’s slower play, yet, competitors of all skill levels use these balls for practice and recreation on hard turf fields due to their resilience. Machine-stitching is the most stand-out visual difference between match balls and training balls and it offers a consistent touch for any player.
