It's a great work boot leather for sure, and truly Americana.
But given the material cost and the actual quality of the leather, better suited for sub $500 boots.
I certainly don't miss the days back in 2011 when absolutely everything was made with CXL. Now everything is shell which isn't so much better - where's the grain? Is it leather if it has no grain?
I recently saw a Japanese boot maker offering Baker's oak bark leather, which is pretty cool.
Yes, I think CXL, various latigo leathers, etc.
I think for strict repro boots those leathers are great.
