The Nome 405 belly shaft is adjustable. PING was the first major golf company to introduce a USGA-approved adjustable-length belly-putter shaft. An adjustment tool loosens a stainless steel ring, allowing you to easily self-adjust the length within a nine-inch range to optimize the fit and performance. This mallet-style putter is offered in three different shaft bends to fit Straight, Slight Arc, and Strong Arc putting strokes. Our research shows that matching your putter to your stroke type is the key to building a consistent stroke and making more putts.
