I'm not really a big fan of Columbia shoes, but after seeing the discounted price. I decided to buy this one. But of course the shoes is also of good quality. Its a breathable but not water proof (im not a fan of goretex shoes), light and cushion trekking shoes. Its so comfy that it doesnt need breaking in. It has the new techlite midsole technology. The main sole is columbia omni-grip. In the two recent climbs that I used this shoe, so far it meets my expections. I just hope it will the same for my upcoming major climb. If theres one thing I want more is that the sole was made of Vibram.
