The Adidas Starlancer Performance soccer ball is great for beginners and experienced players. The inside of the ball is a nylon-wound carcass that is highly durable. The outside of the ball is composed of a special TPU material and is designed to withstand hard impacts. The ball arrives deflated, but once it is inflated the butyl bladder keeps the air secured inside. The bladder also gives the ball it’s round shape. The ball is available in a bright pink and blue design as well as a bright green and black design.

Latex bladders are used in high-quality balls. These kind of bladders are soft and provide good feeling. They offer better response and bounce than Butyl bladders, but the downside of this kind of bladder is they don’t hold the air for too long. As a result, they require filling more frequently. Air escapes due to micropores on the cover, but nowadays some balls are constructed with carbon latex bladder to help to close these micropores. As a result, the balls can hold air for a longer period.
Adidas says its design was motivated by Russia's urban landscapes. It uses textured graphics and a metallic sheen to bring a modern look to the classic design. The ball is made of six panels of thermally bonded TPU and about 15% silicone. The materials allow for better trajectory, accuracy, responsiveness, and low water absorption. It also feels well-padded and slightly lighter than previous match balls.
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.
The Telstar 18, the design for the 2018 World Cup in Russia, is as close to a perfect sphere as you can get. It has subtle pimples and six thermally bonded panels designed to avoid knuckling, which is the characteristic bobbing and weaving movement when a ball is kicked without spin. All 32 teams have been able to play with it since November in preparation for the tournament, which runs from June 14 to July 15. But despite its similarities to the old ball, players have grumbled about the Telstar 18. Compared to the last few World Cup balls, the Telstar 18 is very similar to the ball used for the 2014 World Cup in Brazil. It won’t fly quite as far down the pitch, and will wobble in the air a little differently, but aerodynamic testing suggests it will be more stable in the air overall.
