A slightly rounded toe shape and wider area in the front of the shoe improve traction and comfort while foam sockliners mold to your feet for improved fit. The Sport BOOST 3 is also built with an “Energy Sling” design that helps direct energy transfer more efficiently.
There are differences however including most notably more adjustability in the form of Titleist’s SureFit CG technology that allows for more specific spin rate and launch angle tuning. The TS3 also features a more traditional pear shape and tends to produce more of a mid-launch as compared to the TS2’s higher launch.
The new Titleist TS2 and TS3 drivers and fairway woods are the result of a concerted effort by the company to improve distance results in its long clubs. Titleist engineers have been designing top-notch drivers for some time as witnessed by major wins by players like Jordan Spieth Jimmy Walker and others.
