Sometimes the best golf advancements come not from fancy new materials, but from simple observation. For example, we tend to hit two-thirds of our putts towards the heel, due to a parallax effect caused by our eyes being inside the center line of the putter. The TaylorMade Spider X Putter uses an optically engineered True Path alignment system to overcome this, leading to more on-center hits and thus made putts. The X's design also tones down the "jet engine" look of the original Spider, with a more traditional shape, a heavy metal frame to minimize twisting, redesigned weight ports, and thicker Pure Roll insert for better sound, feel, and roll. Available in copper or navy blue.
