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.
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.
“Had I seen the drag curve for Jabulani prior to the 2010 World Cup in South Africa I would have been calling FIFA and Adidas saying please don’t use this ball,” Goff says. The fact that the Jabulani became unpredictable and beach-ball-like during these long passes really helped Spain win in 2010, Goff says. The Spanish team relied almost entirely on short precise passes, without long kicks that became unstable with the Jabulani ball. “That was the perfect example of a team that really fit the style of play for that ball,” Goff says.
Only size 5, and size 4 are available for this. Although this should not be a major problem as this is for recreational play and practicing purpose, so kids are ok to play with this as well. In fact, the ball that will be given away to the developing countries will be used by the kids mostly. If you are buying this for an adult go for size 5, and if you are buying for kids or youth players then better go for size 4.
Whether it was a size 3, 4, or 5, we found that the Adidas Starlancer performed as it should. This allows beginning players at any age to begin getting a feel for what it is like to have the ball at their feet. There are two color options that come with the Starlancer as well and each performs as it should. For normal passing, crossing, and shooting drills, we found this soccer ball to be true to form. The machine stitching is strong and offers a fairly long lasting performance.
Well, panels are not any different component. Panels are the segments or octagon quilt that are seen outside the balls. Of course, nowadays you will find some other shapes besides octagon. FIFA official balls usually contain 32 panels. But nowadays you will also find 26, 18, 14, 8 or even 6 panels with different shapes and designs from those of conventional balls.
This soccer ball is specifically designed for entry level youth players so that your young boy or girl will have no problem controlling this ball. In contrast to several of the soccer balls for kids on our list, this ball does not come inflated making for a learning experience for your young one. Kids can learn all about the mechanics of properly inflating a soccer ball before they began to play with it. The vibrant color of this ball paired with a dark asymmetrical pattern on the foreground presents a wonderful visual sensory stimulation experience for your young kid.

Crafted by Adidas, the Telstar 18 is the official ball of the FIFA World Cup. Drawing inspiration from the company's first World Cup match ball, which debuted at the 1970 tournament in Mexico, the new ball reimagines the 12 black panels on an otherwise white design. Fun fact: the iconic original black and white ball was made that way to be more visible for black-and-white TV viewers, and it was dubbed the "star of television."
A: Butyl bladders are an excellent choice for the interior of soccer balls because they create an airtight seal in the inner compartment. This helps greatly with air retention. Even better, you will not have to keep inflating soccer balls that contain a butyl bladder for the fact that they hold air much longer than soccer balls that don’t have a bladder made from butyl rubber.
At the World Cup level, these tiny changes in a ball’s aerodynamics can legitimately impact a team’s performance, so the intense scrutiny of the World Cup ball is perhaps to be expected. “You could argue that it’s the most important piece of equipment in the most popular sport in the world,” says John Eric Goff, Professor of Physics at University of Lynchburg.
As per the kids who can use this ball, it is designed for users who’re 3+ years of age. Children can play with this ball, and when it is quite soft, they can learn the art of blocking as well as heading a soccer ball without hurting themselves. Finally, it comes in 4 different colours as in addition to Blue/Black, customers can purchase it in Orange/Black, Yellow/Black, and Orange/Blue colour combination.
Whatever ball you decide to purchase try to prolong the life of the ball by taking care of it. Don’t let your players stand on the ball or try to change the shape. Don’t leave them outside between practice sessions as prolonged exposure to sun or rain will damage the surface of the ball and dramatically reduce its life. Always try to keep balls clean after play by wiping them down with a damp cloth.
In terms of durability, you can’t really go past Select. The polyurethane cover on the Numero 10 is tough enough to withstand dog bites and general wear and tear, but still feels nice and soft when kicked. Although this ball is a bit more expensive than other replicas, it comes with a two-year warranty for peace of mind when buying. It also retains its bounce very well over the years – perfect for practicing volleys and clearances.
Weighing 14 to 16 oz., a No. 5 ball is the largest-sized ball, and players 12 and older can feel like grownups upon graduating to this size, also used by adults. Its circumference is 27 to 28 inches. Prices can start at $15 for a cheap training ball and up to $150 for a match quality ball, especially if it is a special edition issued in conjunction with the World Cup or Olympics.
If you're headed to the park to play a quick pickup game, brightly colored adidas soccer balls can help make it easy to distinguish your match from other games that might be being played nearby. Dribbling skills conducted with mini Nike soccer balls can hone your control skills, so you can glide past defenders with ease. Look for 12-panel soccer balls that provide a true, accurate flight with each strike, and rubber butyl bladders that offer excellent shape and air retention, so you can quickly jump into a game without looking for a pump. If you prefer playing indoors, check out a futsal ball that's slightly smaller than regulation soccer balls and is designed for use on hard indoor courts.
