Every 6 months or so I use a paint brush and paint on some homemade leather sole oil. I don't know if this actually does anything, but I like to think that it moisturises the leather. I also do this if the shoes have been caught in really wet weather - I find the soles dry out if I'd forgot to put dubbin/shoe grease on and the oil helps to moisturise them. Though I honestly don't know whether this does anything more than the dubbin would.
If there was only one product I could use, it would be a beeswax based dubbin/shoe grease, like the Bee kind stuff. It protects the leather and conditions it. I find most other products superfluous.
I will use a cleaner/conditioner when I want to smoothen out a shoe that has too much polish - but since I don't use shoe polish much this isn't very often.
