Zenergy Flatso The SuperStroke Flatso putter grip features a distinct pentagonal “Flatso” profile: a wide, flat front grip shape with five pronounced edges. Now with Enhanced Spyne Technology and Multi-Zone Texturing, the Flatso Series has been refined to offer even better feel and feedback. The SuperStroke Flatso putter grip is one of the most popular grips played on professional tours. PGA TOUR professional Jordan Spieth trusted the Flatso grip for each of his three major championship victories. Features Include: Enhanced Spyne Technology – The new Spyne Technology has an improved, embossed ridge along the underside of the grip, engineered to make it easier to square the face at impact. New Multi-Zone Texturing – Strategically placed textured in high-sensory areas designed to optimize feedback and comfort from the incredibly soft polyurethane outer layer. No Taper Technology – Super Stroke's patented No Taper minimizes grip pressure with an advanced parallel design that enables golfers to quiet their hands and add consistency to their stroke. Tech-Port – Located at the top of SuperStroke grips, Tech-Port allows golfers to easily add game-improvement options including the patented CounterCore weight system and performance tracking sensors. CounterCore weight is not included with the grip. Zenergy Flatso grips come in 6 colors and 3 sizes.
