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."
In 1937, the regulation soccer ball put on a little weight, increasing from 13-15 ounces to 14-16 ounces. Soccer balls used to be made exclusively of leather. Not so these days! Current technologies have come up with leather-like synthetic materials that are softer, more lightweight, water-proof, and perform as well if not better than leather soccer balls. As for the look, early soccer balls were tan but difficult to see from the stands; although white leather-washed soccer balls are known to have been used. White soccer balls replaced their tan predecessors in the 1950s, and were composed of 18 panels. Black spots were added to allow soccer players to track the ball's swerve. Today's soccer balls come in an array of colorful designs and styles to suit every player.
A radically new configuration reduced the amount of panel touch points forming a smooth and perfectly round exterior that improved accuracy and control. Prior to the Teamgeist, the surface of World Cup match balls had notable differences depending on where a player would strike the ball due to seams, ridges and other imperfections where panels come together. The revolutionary propeller design of the Teamgeist minimized corners and created a smoother surface for improved play. The ball was designed with traditional colors of the German flag and was accentuated with the golden color of the World Cup trophy.
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
