I bought a pair of these based on a review in a magazine. They fit my narrow, low volume feet very well. Large volume or wide feet would definitely have a hard time with these. The break in time is non-existent, and they are super light. Waterproofing is good, and they breathe well. However, I wore them on day hikes in Acadia NP (very rocky) for about a week, and on a 50 miler in the NJ pine barrens. Both shoes developed cracks in the Vibram outsole, right where the heels are. I glued them up to finish the hike, but they continued to tear. I read another review that also stated they tore on the outsole, only at a different place. I sent them back to Timberland and they replaced them no questions asked within two weeks. So, I'd say it's a great boot if you don't mind sending it back to Timberland every season. As long as they keep replacing them, I am fine with that.
