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.
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.
The outer casing of a soccer ball is composed of panels made from synthetic materials, such as PVC, PU, or a combination, sewn or glued together. Soccer ball casings are rarely leather anymore, since leather tends to absorb moisture making the ball heavier and not perform as well. The number of panels or sections of the outer casing varies according to design. Most professional soccer balls are the 32-panel design. More panels mean a rounder and stabler ball, and a more accurate flight.
2006 Teamgeist Adidas The Teamgeist is a 14-panel ball. Each match at the World Cup finals had its own individual ball, printed with the date of the match, the stadium and the team names. A special variant, the gold-coloured Teamgeist Berlin, was used in the final match. As in 2003, the ball used for the 2007 Women's World Cup was identical in performance to the ball used in the previous year's World Cup, but with a different visual design. 
The highest in cost, top match balls for elite soccer players are constructed with a supreme quality cover, backing, and bladder for the most predictable flight pattern and striking ability. Some of the most impressive official match balls on the field are made with the threadless, seamless, beveled edge (TSBE) technology which provides a seamless surface for touch and less water uptake to stay in control. adidas soccer balls that pass a demanding series of tests, set by FIFA, on the shape, weight, performance, rebound and water absorption have the highest ranking a soccer ball can get. Most adidas training and pro match balls are FIFA approved so you can lead the charge down the pitch.
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.
Premium Match Balls. These are the most expensive soccer balls that you’ll find on the market today. They are FIFA-approved balls, so they meet all of the standards necessary for international play. Air retention, water-resistance, and performance are far superior when compared to a training ball. Virtually every professional league uses a ball of this quality for game play.
This 12-oz. ball works for players between 8 and 12 years old and has a circumference of 26 inches, larger than a size 3 and smaller than the size 5. This age group tends to play on a field of about 30 to 50 yards, writes Deborah W. Crisfield in "The Everything Kids' Soccer Book," with a goal size of around 6 feet high and 18 feet long. Again, the scale for the U12s falls between that of the U8s and that of the older age brackets for the No. 4 ball and the game as a whole. Some leagues may limit the No. 4 ball to U10s instead of U12s, so check league rules before making a purchase.
A Futsal ball is basically an indoor soccer ball used for playing 'Futsal', a term literally meaning 'indoor football'. Futsal is a kind of soccer played on a basketball-sized court using a smaller, heavier, less bouncy ball, and demands many of the same skills as outdoor soccer. Size-wise, FIFA-approved futsal balls are just shy of 25 inches in circumference, slightly smaller than a Size 4 soccer ball. The ball is created with less bounce to facilitate indoor play.

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
