Since most young players seem to only have 1 foot, this is a fun game to get them to use that 'other' foot.

Have each player line up with a ball with their dominant cleat off and in a pile. Have them race to a cone in the distance, dribbling only with the 'cleated' foot. First one back is the winner.

You can also have them put their shoe back on, then take the other off and keep going. This gives them a quick break while they change shoes!

Of course, only do this is game if the field and weather allow it!
