SPOTTED: Mizuno ST190 and ST190G drivers
Three Mizuno drivers have recently been added to the USGA Conforming Clubs list: Mizuno ST190 (9.5 degrees), ST190 HL (10.5 degrees) and ST190G. While the image links are currently unavailable on the USGA website, the ST180 and ST190G drivers have been spotted in person at the British Masters.

Judging from the photos, both drivers have Mizuno’s familiar Wave Technology — an accordion-like speed channel seen in the ST180 drivers — and “SP700 Coretech” faces.
The ST190 looks to have a fixed weight in the rear portion of the sole, while the ST190G has a “Fast Track Technology” sliding weight in the heel of the sole; judging by the labeling, that track will help golfers adjust between draw and fade trajectory biases. Surely, the Mizuno ST190 HL was not spotted out at the British Masters because one would assume it’s a “High Launch” product made for those who need more launch; that tends to be higher handicaps rather than Tour pros.

The driver being tested above looks to be equipped with a popular Mitsubishi Tensei Orange shaft. Compared to the ST180 drivers, it’s also clear Mizuno is going away from the blue color scheme to a glossy black look.
Mizuno is not commenting on details/tech at the time, so for now we are left to speculate on the drivers.
See what GolfWRX Members are saying in our forums about the ST190 drivers.

What are the best golf socks? – GolfWRXers discuss
In our forums, not everything is about club selection and shaft options. A heated debate has bubbled up surrounding the best sock options players can wear on the course.
@CletePurcel asked:
“Just bought 2 new pairs of FootJoy shoes and trying to find out the most favorable socks to wear. I try to walk 9 holes two to three times a week and good socks are a must. Thanks in advance.
Members in the forum chimed in with their favorite footwear accessories. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- Maroon_19: “I’ve only worn Kentwool socks for golf for the last 8 years – regardless of weather. I walk 90% of my rounds and play anywhere from 50-75 rounds a year (going to go up as I just retired). They only get worn for golf. As long as you care for them, they’ll care for you. Have had zero blisters with them. I just started using my second set of 8 pair for our Bandon trip earlier this month. The old ones will now go into the daily wear rotation. Still good after all these years.”
- smoova: “I’ve had good luck with Swiftwick. Walk every round 12 months a year in Colorado.”
- Hawkeye77: “FJ Pro ProDry is what I’m usually wearing just because I have more of them, but I’ve got some Smartwool socks I love for the wool aspect – they sell them as running socks. The thicker socks are better for certain shoes. I’ve gone merino/other wool in almost all my socks – athletic, “dress” and so forth – no more “Orlon”, lol, some golf socks are the exception.”
- th6252: “Another vote for Kentwool, honorable mentions to Balega and Falke(thanks to someone on this forum for turning me onto the RU3).”

I happened to catch the Mizuno rep yesterday at our local golf shop and he let me hit both of them. They look amazing and feel even better.. both seem very easy to hit and forgiving.. they are going to be unveiled in Orlando in February can’t wait to get fitted for one

Anyone else read WINE Technology on the sole?

How about WAVE Technology, you know, like the waves of the sole. I have the 180 and it is good, and very calming. hmmmmmmmmmmmmm POW.

SP700 face is suppose to be made of some high end material other OEM’s use to but stop using because it’s too expensive.

I’ve never hit a Mizuno driver (or seen one in person actually) but I think going with the black crown has to make it look better at address. I know its just a visual thing and but a blue head is a bit aggressive even if blue is Mizuno’s color scheme.
Interested to hear more though.

Mizuno drivers are so underrated. Just try one I’m sure you’ll be surprised. I went to a driver fitting, tried Callaway, TaylorMade, Ping, and others. The Mizuno ST-180 out performed all of them. Superb.

Shame about the shiny crown, will never buy another driver with a reflective crown.

Wish they would try and make their sliding weights semi good looking instead of just slapping a hunk of metal and a screw together.

Mizuno rep just visited my golf shop with these drivers today. They will be unveiled at the PGA show in Orlando. Stock shaft will be the Atmos but are saying no upcharge for any shaft they offer. They have gone away from blue, and they look really good.
