Abstract
An improved putter including a pair of runners attached to the bottom of the putter head. The runners take up less than the entire surface of the bottom of the golf club. They raise the blade of the putter above a ground surface. Their surface area is less than that of the bottom of the golf club, so the interaction with the ground is significantly reduced. This minimizes the interaction between the putter's blade and the ground during putting. The chances that the putter squarely strikes the ball without catching on the ground is increased. The runners also raise the blade to a level to at or near the golf ball's equator. This improves the probability of the blade striking the ball with an upward blow during a swing. The upward blow imparts a desirable top-spin roll on the ball. Undesirable spins which make the ball deviate from its intended path, such as back spin or side spin, are eliminated.
