Inflate soccer balls to the pressure of 6-8 PPI (pounds per square inch). A pressure gauge will tell you when the air is enough. Under or over-inflating a soccer ball will shorten its life in one way or another. When under-inflated, the ball will not be resistant to the impact of kicks. On the other hand, over inflation will stretch out the bladder and put pressure on the panel stitches.
Whereas plenty of manufacturers that we reviewed opted to go with a soccer ball that was more durable than responsive, Mikasa takes the opposite approach and focuses primarily on the touch that their ball can provide. This is most apparent in the soccer ball’s choice of casing material. The synthetic leather casing of the Mikasa is by far the softest and naturally responsive-without the inclusion of texture-out of any other soccer ball we reviewed. https://www.youtube.com/watch?v=3OKagE2ZIRA
