Designed 90 degrees toe-up. This putter is shafted the most rearward from center of all Formula Series putters, with three lines to help you align properly. Formula [90] also features a multi-material construction, allowing for a very forward center of gravity and massive MOI, making this design extremely forgiving on mishits.

Formula [90] is a zero-torque design that will stay square throughout your stroke, making it the perfect match for a golfer looking for as little arc as possible. Eliminating the variable of player-added face rotation can simplify putting for many players allowing for more consistent face angles and start lines. Formula [90] works best for players seeking to create a straight-back, straight-through putting stroke.
