What I use is pretty basic. Couple of different show polishes. On the top there is a natural tan shoe polish and then a brown. The brown I mix with some olive oil to make it easier to work with and work into the leather more. I do this layer first so use a color that matches back to your leather. I work this layer over the boot and let is sink in. Then I go back over with the natural and then give it a good buff with a decent quality bristle brush.
