Need advice on how to maintain Lattanzi's

I purchased the most amazing set of Silvano Latatnzi's off of Ebay about a year ago. I've only had the chance to wear them twice. I normally just take my shoes to the local Nordstrom to get a shoe shine, however the leather finish on this pair is so special I am hesitant. I don't want to change the coloring or do any damage to these beauties, so I was hoping someone could help me out. As it stands I haven't ever taken the time and effort to shine my own shoes.

I know Lattanzi sells some of his own shoe care products, but I think I remember reading here that it was just some re badged Kiwi. What do I need to purchase to put a nice shine on these shoes? Again I have never put any products on the shoes since I purchased. I hope the few times I wore them without any maintenance did not do any serious damage.

And can anyone give me a quick tutorial on how to use the products? I would really love to get these to look their best.

Here is a picture of the shoes:

I would use renevateur and neutral saphir cream/polish. The coloring may change over time but they will look even more beautiful with a natural patina.
