Khombu Terrain boots: I found them comfortable with no break in required. They did wear quickly. Hiking a minimum of 20 miles per week. In about 6 months rocks were breaking through the soles. What surprised me even with almost no tread they slip less than a pair of Hi-Tecs with about half the tread left. Though I am disappointed with with the life of the soles. I do prefer it over the last two pair of Bass hiking boots which fell apart in the same time frame. I would rather hike with thin soles, than finish a hike, holding a sole with plenty of tread.
