Mizuno ST-Z 230 & ST-X 230 Driver Review

By: Liam Moore | Tue 25 Apr 2023

Mizuno have treated their loyal customers with two drivers for the 2023 season, both offering something different to the other.

The ST-X will be tailored for the majority of players, as it features plenty of technology to salvage off-centre strikes.

On the other hand, the ST-Z is the low-spinning option but the driver still includes plenty of forgiveness when needed most. You can watch Golfshake Equipment Expert, Ryan Rastall, test and review both drivers here or on YouTube.

Mizuno ST-X 230

The ST-X has been created in a draw bias design and the technology included will help rocket ball speeds to ensure you’re comfortable off the tee. Mizuno’s CORTECH Chamber takes stress from the clubface and creates an additional energy source, whilst simultaneously relocating weight closer to the clubface to reduce spin properties.

Additionally, a Unified Sole Composite consists of a carbon sole plate and it allows weight to be pushed to the limit to ensure overall stability and comfort during the swing. The workable design is intentional, and the weight located closer to the shaft axis can encourage either a draw biased outcome or workable conditions - dependent on the skill of the player. Finally, a Quick Switch Hosel allows golfers to tinker with up to four degrees of adjustability.

What Ryan Says:

“There’s draw bias in this model and it looks very nice in the address position; it’s confidence-inspiring with a bigger footprint. It feels really nice and solid off the face and it definitely has that carbon crunch sound.”

Mizuno ST-Z 230

Mizuno ST-Z Driver

Mizuno’s ST-Z driver features almost identical technology with a few tweaks that should appeal to most players. Firstly, instead of the draw bias found in the ST-X, the ST-Z features a straight bias with excellent stability from off centre hits. Again, Mizuno’s CORTECH Chamber is responsible for relieving stress from the clubface and creating an additional energy source.

The design focus is a mixture of deeper CG and shorter CG distance, which helps produce a balanced and workable tool that can be manipulated from both directions. Whilst the classic Mizuno aesthetics remain, the ST-Z has a striking feel off the face and one that will likely leave you searching for more. On average, ball speeds are up between 2 - 5 mph, which will add slight distance to those who seek it.

What Ryan Says:

“Both drivers look similar in the set up position, with both inspiring confidence due to the shaping. It sounds a little different - crunchier and harder - but from a feel perspective, it feels a little bit better than the ST-X model. I definitely prefer this model and I’m still getting too much height, but overall, these drivers are very, very good and you should consider this brand if you’re in the market for a driver in 2023.”
