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.
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
