These days, you've probably seen a number of top touring professionals -- PGA Champion Jason Dufner for example -- sporting an oversized grip on their putter.
If it didn't work, they wouldn't be using it, right?
Chances are that grip you're seeing is one made by a company called, SuperStroke.

So what makes a SuperStroke oversized grip so special? With a smaller grip, a golfer has a tendency to squeeze too tightly, which can be cause for unnecessary wrist action that can undoubtedly throw your golf ball off its intended line.
SuperStroke oversized grips take "the hands out of it" so to speak. It promotes even grip pressure with both hands, creating a smoother, more consistent putting stroke.
According to SuperStroke, "Electromyographic testing of golfers at the Milwaukee School of Engineering found a 32 percent reduction in grip tension with the SuperStroke versus a conventional smaller putter grip."

In layman's terms, an oversized grip produces a more-square face at impact, leading to better putts and a better feel for distance.
SuperStroke offers several different sizes, and the grips will fit any conventionally shafted putter.
If you're looking to improve your putting, you may want to give SuperStroke a try. Depending on model, the grips range in price from $11.99-$24.99.
