Not personally in need. Just seen multiple posts recently looking for a Utility glove.Just measured it, depending on where you keep the tape at the bottom of the heel.....I’m going with dead on 12.25”
The hand stall isn’t as big as you’d think for this particular glove, it’s not real tight, but not real big either.
And you’re right, not a retail model. This is 1 of 99 that Chad at SoftballFans had made, it’s a Horween SBF exclusive. This one is number 77.
The Pro504 is on the Rawlings builder as a custom, but not in Horween. You could order a custom in Jtan leather and have the wrist closure already laced at the narrow setting.
Reach out to @22Lefty, he’s got my first 504, not sure if his DD is using it, or if he is? He may have some valuable input for you.
