You should also try to keep the ball at the correct pressure. Do not over or under pressurize a soccer ball. Use the manufactures recommended air pressure that is printed on most balls. Most soccer balls have a pressure rating of 6 to 8 lbs. or 0.6 or 0.8 BAR. It is recommended that you use a pressure gauge to measure the exact amount of pressure in a ball after inflating and before use. It can also be a good idea to deflate the soccer training ball after use to reduce the pressure on the seams and stitching. Reflate the ball to the appropriate pressure before using it for a game or training.
Over time, many soccer balls tend to go out-of-round, especially if they are well-used. The Glider is designed to maintain its shape without losing air thanks to the firmness and consistency of the butyl bladder. Under regular use, we found that the air pressure was consistent enough that we didn’t need to add more air to the ball. If you play in organized soccer, then having consistency from the practice ball to the game ball is very important for skill development. The machine-stitched panels offer that experience for most players, even though the ball has the standard panel design.
Everything becomes scaled down for smaller soccer players compared to the adult game. Kids play on small fields nowhere near the size of a full regulation field 100 or more yards long, with as few as three players compared to 11 for grownups. Even in a league, parents may serve as referees, games may last only 20 minutes and scores more than likely won't be kept. In keeping with this small world, kids' soccer balls are also smaller.
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
