I just bought a set of open front leather horse boots

I've wanted these for soo long! I'm soo excited!
Now I just want to make sure that I do all the right things... so that they last... cause they were pricey!!
So I was told that I have to oil them before using it... or else it might crack.
So should I just go buy some saddle oil/conditioner (or neatsfoot oil) and just take a damp cloth and rub it over a few times? Or do I need to soak it in the oil?
And what else should I do for regular maintenance... how to care for them, etc...
Thanks
