Mizuno is again using what they call the CORTECH Chamber, a steel weight in the sole behind the face encased in thermoplastic urethane, which they say moves impact stress away from the face, lowers the spin rate and puts more energy into the ball.

They also have made the overall profile lower and wider giving a neutral lie angle at address. The face is a Beta rich LFS Titanium with a varying thickness pattern on the interior to enlarge the sweet spot and preserve ball speed.

Chris Voshall of the company said, “The goal of the ST-MAX project was to engineer the greatest MOI and performance from off center strikes conceivable – but not sacrifice ball speed or make the profile too cumbersome to look at.”

The companion ST-MAX 230 fairway woods are $300 each and ST-MAX 230 hybrids $250 each.
