Identifying the right model
- Large ST lettering and bright blue panels cover the black sole with a white runbird logo; match the Z on the head, because the ST-X 230 sole looks similar.
- 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 2023-06-03.
- Mizuno publishes each head with a loft and lie range; the hosel setting on a used club decides where in the range it sits.
