If you are talking the current captoe shell boot BB sells (C&J for BB) - $998, you most likely will not be able to achieve the same level of shine of various Alden shells, no matter what you do. I have them. Mine shined nicely after an application of saphir reno, but still not to the level of some of my Alden shells. Don't worry about it .... they are still great boots.
I don't know what C&J do to their cordovan, but they're a royal PITA if you want to get that cordovan to shine.
When new they're really loaded up with brown polish which gives them kind of a dull finish.
It takes a lot of buffing and brushing to get rid of it. Saphir reno does seem to help.
After a while you can get rid of the excess and it's easier to maintain the shine.
When I was a cordovan newb, I made the mistake of using too much brown polish on my Marlows. It didn't do any damage but it make the dullness worse and took even more time getting rid of the excess.
Not sure the picture shows the shine well, but I feel as though the Mac method does well to shine my C&J-(RL) Marlows up nicely. These are about a month old and I haven't applied anything to them but a horse hair brush and a flannel buffing rag. I think they look better than my Cigar LWBs with the same treatment.
