I first purchased Salomon backpack hikers for my husband back a few years ago, and the first pair lasted for over 3 years of heavy use; extremely heavy use. They worked great, kept his feet dry in the hottest of weather and during the wet season as well. The Gore-Tex lining is the best idea. The miles he put on them of steady walking for over 9 hours daily we can only imagine. These were the sturdiest and most comfortable hikers he had ever worn, I've have bought Salomon's since and something isn't the same, the glues, the materials or something, as now they only last for a bit over 1/2 the season. On one pair the sole started coming off, and the heel wears down sooner. Still the most comfortable with their terrific cut, and the wicking is terrific, and works wonderfully well, amazing really. Perhaps they have changed something where they're manufactured, different suppliers or just what I don't know, but wish they would go back to how they were, the best boot around.
