In association football, the ball is predominantly struck by the foot. Footedness may refer to the foot a player uses to kick with the greatest force and skill. Most people are right-footed, kicking with the right leg. Capable left-footed footballers are rare and therefore quite sought after. As rare are "two-footed" players, who are equally capable with both feet. Such players make up only one sixth of players in the top professional leagues in Europe. Two-footedness can be learnt, a notable case being England international Tom Finney, but can only be properly developed in the early years. In Australian Rules Football, several players are equally adept at using both feet to kick the ball, such as Sam Mitchell and Charles Bushnell (footballer, retired).
