When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
This ball truly lives up to its name as a “glider,” having a stable flight path when shot and a nice feel when passed. The surface is relatively grippy, which is great for goalkeepers looking to practice their catches. Because the ball isn’t as slippery as some other replicas, you can shoot it with a bit more swerve, and dribbling and skill moves are a bit easier.

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.
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.
