As a response to the problems with the balls in the 1962 FIFA World Cup, Adidas created the Adidas Santiago – this led to Adidas winning the contract to supply the match balls for all official FIFA and UEFA matches, which they have held since the 1970s, and also for the Olympic Games. They also supply the ball for the UEFA Champions League which is called the Adidas Finale.
During the 1900s, footballs were made out of rubber and leather which was perfect for bouncing and kicking the ball; however, when heading the football (hitting it with the player's head) it was usually painful. This problem was most probably due to water absorption of the leather from rain, which caused a considerable increase in weight, causing head or neck injury. By around 2017, this had also been associated with dementia in former players. Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality.
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
