Every player who plays in a professional soccer league must have cleats. The best cleats are made out of rubber or plastic and the best ones to wear don't hurt your feet. The players also wear jerseys, loose shorts, long socks, and shinguards. The goalie wears a different color jersey than the players so the players can tell who can and can't use their hands. Sometimes a goalie will wear a mouthguard. Soccer is played using a ball that weighs about 14-16 grams.  The smaller of the age of a player the smaller the ball they play with will be.
