I use this boot for work. My job requires a lot of hiking with gear and this boot holds up great. They break in very fast. After a week they felt like they had broke in. They aren't to stiff but still allow you to toe in on step grades. Rubber feels great on rocks. Very light for how solid the boot is built. High quality and comfortable. The double tongue is something I haven't messed with much. I've only left it up and seems to add to comfort once it shapes to your foot. Research sizing before you order. I'm more like a 10 3/4 so I order an 11 in most boots. I ordered a 10.5 in these and the fit was perfect. My only complaint is I wish the heel was a little taller for my pole climbers(lineman). Otherwise great boot and will buy again.
