Inside Down the Line™ Putting Track Training Aid by Momentus teaches you to putt like the best players in the world.  Simply place the heel of your putter against the vertical portion of the track and as you make the stroke allow the putter head to stay in contact with the Inside Down the Line Putting Track at all times.  The putter head swings a little inside, then down the line on the through stroke.  You will make so many more putts and it will feel natural and effortless.  Train yourself to repeat the perfect putting stroke to sink more putts and lower your score.  The Inside Down the Line Putting Track is an ideal aid to improve your putting permanently.
