A little disappointed with the quality of these boots. The left boot arrived with what seemed like shoddy glue-work, there was a tiny gap where the toe joined the bottom of the sole. I thought it was nothing to worry about, I broke them in with a couple of quick hikes, and took them with me to Nepal on a 12 day trek. On day 5, the little opening grew wider, by day 8, the right side also started separating. Had to walk around gingerly, hoping it would hold till the end of my trek. Not good.
Other than that, the gore-tex lining was great, and the grip on these shoes were pretty good, was good on everything except ice.
