Both latex and butyl bladders have their own set of merits and demerits. Latex bladders are softer, provide better control, feel response, bounce, etc. However, the air retention of the latex bladder is lower than the butyl bladder. Generally, latex bladder is used to make the official match balls. On the other hand, the butyl bladder tends to retain the air longer than its latex counterpart, but it doesn't give the same amount of bounce, and liveliness. Butyl bladder is used to make the practice soccer balls in most cases.
