The stealth has been updated slightly for 2013, our third iteration of this ultra comfortable premium leather golf shoe. The stealth has moved from the Ergo-Traction 2.0 platform to our new Ninja platform which provides enhanced feel and flexibility. The upper is made from our proprietary premium waterproof leather which is very soft and ridiculously comfortable. From an upper styling standpoint we only made one small update by adding rivets to the eyelets for a more clean and sophisticated look. The TRUE stealth comes with a two year limited waterproof guarantee.
