The Mizuno JPX 900 fairway wood has a new Infinite Fast Track in the sole. A 15-gram weight adjusts the launch angle and spin, by moving the weight forward or back.
The JPX 900 fairway wood also has what Mizuno calls a “Shockwave Sole.” It flexes at impact to give more ball speed to shots hit across the entire face.
A “Waffle Crown” design on the JPX 900 fairway wood lowers the center of gravity. This makes it easier to launch the ball higher, allowing it to land softer.
