When a tournament is held (like the FIFA World Cup), the sponsor of the event will design a brand new ball. These are official match balls – they’re used by professionals during real matches. They are designed to the highest possible build quality, have textured surfaces to improve stability in flight, and feature thermally-bonded panels for durability.
This ball also comes in sizes 5, 4, and 3 and ships at one pound exactly, and it does not appear to come inflated. This soccer ball ships within the US and is not eligible for international shipping. For the low price and quality of this ball, it is totally worth the value because the exact ball that the pros use is around $100, and this pro soccer ball replica is a fraction of the price.
Footballs have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings. Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating footballs made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that footballs developed into what a football looks like today.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
