Identifying the right model
- The black sole carries large ST-Z lettering, a white runbird logo and a silver weight at the rear.
- Match the full model name and any suffix (LS, MAX, X, D, ONE Length, SELECT) on the head as well as the printed loft.
What to check before using the reference
- The figures come from an Internet Archive capture of Mizuno’s US product page dated 2021-10-27.
- Mizuno publishes each head with a loft and lie range; the hosel setting on a used club decides where in the range it sits.
- This is Mizuno’s 2021 ST-Z page; the ST-Z 220 and ST-Z 230 are later generations with their own records.
