Chasing uncle Mac's shine is like trying to catch a unicorn sliding down a double rainbow. It is not going to happen. The man cheats. He employs a team of oompa loompas who brush and buff 24/7. In addition, his rotation allows him to wear each pair a handful of times a year. (I was trying to be funny, except for the last sentence)
For regular upkeep I wipe w damp cloth, brush each shoe 7-10 mins, quick buff w old cotton tshirt.
To bring back the pop in used and abused shell,
I brush a lot, apply little saphir renovator with my finger, brush a lot again, use very very very little kiwi, brush a lot again, quick buff w cotton tshirt.
I recommend you take care of your own shoes, most shoe shine places have no clue how to treat shell.
Don't think Mac would let somebody else touch his Aldens. I am of the opinion he has forearms like Popeye and Arnie's biceps from his signature method.
