Sure, happy to provide more detail on SYNR-G, which is not only our most stable golf shoe ever, but the most stable golf shoe on the market. The name alludes to the perfect blend of comfort and stability but since you asked about stability, let's focus on that. FYI...for more on SYNR-G, including testimonials from some of the pros, visit www.footjoy.com/synrg.
The shoe was built for high swing speed players who demand stability throughout the golf swing. Turn the shoe over and you immediately notice some of the most important features that keep you locked in place. SYNR-G is the first golf shoe to incorporate FootJoy's new G-Force outsole which was developed over the course of two years and is specifically designed and developed for golfers seeking maximum support and a solid foundation. Another unique feature of the shoe is the Tri-lateral Stability Frame which, when combined with a perforated alloy mid-foot support bridge, cradles the foot and provides a phenomenal stable hitting platform. The Tri-lateral stability frame is noticeable by the three, very unique, "guitar pics" that rise up along the outside of the shoe, providing a phenomenal platform from which to launch!
Aditional stability features have been implemented inside the shoe. Memory foam, the same material used in some mattresses, has been strategically placed around the entire collar and under the tongue which provides a "mold-to-your-foot" custom fit while simultaneously delivering dramatically improved support and motion control. When you first put the shoe on, it may feel a little snug due to the memory foam, but after a few seconds, the foam molds to your foot and you have a perfectly fitting, very stable golf shoe. It's incredible. There's also a HeelLoc zone, located on the heel area of the PU Fit-bed™ which reduces friction and keeps the foot securely positioned throughout the golf swing.
After extensive testing, SYNR•G shoes have proven to increase a
player’s overall base stability- benefiting golfers at every level.
Personally, I've been wearing this shoe all season and it is phenomenal! You truly get a custom fit, it's very comfortable and very stable.
Hope this helps!
