Wow - thanks for posting those photos! I definitely don't want to hasten any darkening (though the shoes look terrific in that second shot!). So...neatsfoot? Would be interesting to see similar photos with that stuff. I'm assuming there's a CXL Care and feeding thread here somewhere - hoping it will be definitive vs. a lot of potentially conflicting opinions...
I think I did buy Alden's cream - I was excited to wear the shoes right away, and they offered to ship my other shoes back so I think I asked them to toss a jar in the box.
I also recently picked up some AE's in natural waxed leather - I'll go find the AE section for some thoughts there beyond saddle soap
You can refer http://horween.com/101/chromexcel-2/. Nick from Horween talks about their chromexcel leather and mention the condition of cxl.
"The last step for Chromexcel is coat of Neatsfoot Oil, so when people ask me how to condition this leather, that’s always my first recommendation."
