Look, the first mistake a new shoe enthusiast makes is he loves his shoe death, literally, they tend to want to start feeding the shoes and polishing them and cleaning them and brushing them and then they start all over again and again until they destroy them.
If this is a new pair of shoes, just give them a GENTLE wipe with a slightly damp cloth, remove all dust and dirt.
Then a light quick brushing with a good horsehair brush.
Then use a very small amount of Renovateur (it does not have to be the expensive one either, it can be the Saphir Renovateur which is not the Medaille D'Or)
Another product which you could use is their Baume http://www.valmour.com/cleaning-products/mat-leather-balm-avel,521.
put small amounts of product, nothing excessive. and then when the product has gone tacky and is almost dry, bust brush gently until you get a shine and the surface accumulation of the product has been removed.
If you want the shoe to really shine I would recommend that you do not start a shining program until you have treated the leather well enough to have made it supple and healthy. This takes at least a few days to do, even for brand panking new shoes straight off the shelf.
To get them ready for a good shining you treat the shoes daily with small amounts of a good product, like Renovateur or Baume Cuir from Saphir until the leather feels nice and soft to the touch.
Then take Saphir "Graisse" http://www.valmour.com/cleaning-products/grease-saphir-medaille-dor,54
Give the shoe one or two applications of "Graisse" and wait at least a day for the product to fully penetrate. If necessary repeat once more.
Then start your first shining regime of shining by using the creams and then, lastly, the Pate de Luxe from Saphir.
There should be no reason to use color unless your shoes have been scraped or scuffed or damaged to the extent that the leather has lost some color.
You would use a "incolor" from Saphir in both the cream as well as the Pate de Luxe.
If you only want to buy one product then buy the tin of Baume Cuir, don't even bother with the renovateur in this case. Baume Cuir should be all you need if you just want the shoes to maintain a good healthy appearance.
Too much hype over these polishes and products leaves people with the impression that care of shoes is highly complex when it is really quite a simple and easy process which we enthusiasts tend to complicate too much.
Get on with wearing and enjoying the shoes and don't try to color them just yet, they still look brand new.
When you really do need to color them, you will find you are going to need to decide on a color and might even have to mix your own color to match perfectly or you will need to put up with using a similar color and build up a nice patina.
