“Are these waterproof? How do they compare to a leather boot that is "gore tex". I hade a pair of Merrell Guides that were awesome and i can't find a good pair of sewn soled boots that are comparable. i like these, but worry about whether they are waterproof enough for mountaineering and bushwacking through dew covered thickets in CO, etc”
These boots are not waterproof but can be treated. These are a great boot that will last a long time and will handle various terrain.
These boots, if properly treated, are actually more waterproof than several pairs of my gortex boots and after 4 years of serious abuse are on track to far outlast them.
