Like a modern day Princess and the Pea - except it's shoes and you ain't no Princess...
I blame Alden QC.
I just use Reno on my brown CXL, but if you want to add color I suppose there's nothing that can quite match it. I've used Mahogani saphir cream polish on my fiancee's brown boots and it's a nice rich reddish-brown which might complement the CXL color.
Saphir does make a line of polishes specifically for cordovan, although I've no experience with it. They have a "cordovan" color (which should be color 8).
Wow... you must have a ton of time on your hands to discover that. I'll have to inspect my collection of Alden LWB. I admire your resolve (if that's what one would call it). I wonder if this means that my 975's and 9751's were actually made in India? jk
