Putting practice device and practice method using said device

A putting practice device comprising in combination:

• a) a first member provided with a planar sliding surface against which the toe of a putter blade is slidable according to a vertical pendulum movement;
• b) maintaining means for maintaining said planar sliding surface on a ground defining a rolling surface for a golf ball, and maintaining said planar sliding surface substantially perpendicular to said rolling surface and substantially parallel to a putting line for said golf ball toward a target;
• c) a second member comprising a portion defining a sight, said portion comprising at least one planar reflecting surface surrounding the sight, said planar reflecting surface being provided on top portion of said second member;
• d) indicating means allowing to indicate the center of sight;
• and
• e) positioning means for positioning said sight above the putting line and the golf ball;
• the eyes of a user being systematically positioned substantially perpendicular to the golf ball when said user has the toes of his feet substantially parallel to the sliding surface and substantially equidistant to the center of the sight, has the toe of the putter blade against said sliding surface, sees the golf ball through said sight and sees his face but not his eyes in the planar reflecting surface.
