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.
It is a common misconception but, believe it or not, soccer was not actually invented in England. Although the sport, known across the pond as football, was revolutionized by the country in the mid-19th century, records actually trace its origin back over 2,000 years to ancient China. Called “association football” when it was played by the British 200 years ago, the terms “football” and “soccer” were both eventually derived from abbreviations of the longer name over time.
One thing which customers often complain about soccer balls is their poor air retention ability. After a few days on the field, the ball starts to deflate which serves as a big problem for anyone who has to use it on a daily basis. However, there is no such thing with the Top Glider as inside this ball is the butyl bladder which is becoming a norm with the majority of the Adidas soccer ball’s nowadays for better air retention.
One of the main reasons but not the only reason to select this ball for reviewing is the great mission of the company. If you buy one ball, they will donate one ball to the kids of developing countries against your purchase. So, this is a “Buy One, Give One” charity model, and of course, it is a good mission where you can also contribute by buying one.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players. https://www.youtube.com/watch?v=j2Xn84L3Kcs
