Waterproof 'Em
Boots that come with a Gore-Tex liner are already waterproof, but it is important that the leather be treated as well. Excess water can make the boots heavy and create water-spots between the leather and Gore-Tex liner. Constant soaking and drying of the leather can damage the fibers, causing the boots to become stiff and eventually ruining the snug fit of the product. When you notice the boots taking on excess water, it is time to apply our Danner Waterproofing Gel. After the boots have been cleaned, apply the gel with a clean rag, and work the substance deep into the pores of the leather. Allow the boots to dry for a few minutes then wipe away the excess. Do not use Danner Waterproofing Gel on nubuc, suede, or rough-out leather boots. Instead, use our Danner Waterproofing Spray, which will help maintain the original texture of those products.

Yes, yes, and more yes. Big thing with most boots is just keeping that leather conditioned. A simple cleaning/conditioning once or twice a year can mean the difference between boots going 2 or 3 seasons versus 6 or 7.
