The Mizuno ST190 combines every known factor to deliver ball speed and driving distance – aligned with our lowest ever spin rates. Mizuno’s ultra-fast Forged SP700 Ti face is enhanced with a lighter CORTECH structure for consistently higher ball speeds. Combined with a large carbon composite crown and Amplified Wave soleplate to convert each additional mph into yards gained.
"The ST190 marks a total change in how Mizuno approaches wood design. We now start the development process with our tour players. The tour tested molds then become our production molds. In the case of the ST190, this produced a high-speed driver with extremes low spin for the tour, but with the capability of increasing spin for lower swing speed players. We also learned to slightly roll back the level of adjustability to gain performance. Losing the central weight track helps reduce the lower end of spin rates and gave us the design freedom to deliver a 3mph ball speed increase on our previous models."

Factory fixed backweight adds 300 gcm^2 MOI for stability from off center strikes.
More than 10% stronger than 6-4 Titanium with a fine grain structure that allows a more complex geometry for our CORTECH face. Internal testing proved higher performance than 6-4 Ti at 90mph, 100mph and 110mph head speeds.
A 12-gram carbon composite crown allows 7 grams of weight redistributed across the ST190 for consistently higher ball speeds and reduced spin rate. Our ratio of carbon crown to bonding area increased to 5:1 from 3:1 on Mizuno’s previous carbon crown (MX500).
A heavily amplified 1st wave configuration expands the ST190 CORAREA for improved balls speeds across the clubface and reduced drop off from off center strikes.
The study of vibration and soundwaves identified the need for internal ribs - creating a more solid, powerful impact sound.
Performance of our exotic SP700 Forged Ti face moves to new levels with improved internal engineering. The ST190 CORTECH face, re-engineered CT ribs and internal structure combine to squeeze ball speed from the entire clubface.
