Those are good boots. Avoid solvent or silicone type waterproofing. I think this was a factor in mine completely loosing the soles. The mid sole just disintegrated. Ozone may have also been a factor. Check them before each major trip. I hope Danner improved the mid-sole on yours.

It is possible mine were defective as I bought them at a big discount.
