The history of soccer balls date back to ancient times. From a couple centuries BC to about 200 AD, the Chinese used balls made from animal skins in a game called 'tsu chu', in which players had to pass them through a net stretched between two poles. The ancient Greeks, Romans, and even the Egyptians are recorded to have enjoyed a similar game that involved kicking a makeshift ball.
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.
