Well I suppose I had in mind the leather/suede type finishes that lined boots often have these days. While it may have no bearing on water ingress it might extend the life of the leather (cracking?) to apply some sort wax or similar product. The other thought is that the boots I have are far from light weight and I could envisage the liner going with the boots having a lot of wear left, in which case, I would consider proofing them rather than binning them.
