Abstract: A practice putter for improving a golfer's putting game having a conventional grip attached to a conventional shaft. The shaft is connected to a head having a concave bottom surface of a predetermined radius. One or more balls are mounted in the bottom surface on an axle, and each ball revolves freely only in the direction of the axle. Each ball is positioned adjacent opposed sides of the concave middle portion. Each ball is mounted on an axle having a shock system that allows the ball to be pushed inward towards the head with the application of a predetermined force thereon. The length of the shaft is adjustable, and the angle determined by the top surface of the head and the shaft is also adjustable. In proper use, each ball is made to contact the putting surface as the head is moved in a straight line guided by the rolling balls.
