Bought this boot at an Army Surplus after trying on about a dozen boots and this particular boot is very very comfy and allows one's ankle to articulate comfortably. I've used these boots hard every day doing ranch work, so I've got maybe 100 hard days in them and they're holding up well. I would have liked to have a Vibram sole. The sole is the one component that's not top-notch, but its not Vibram. The Gore-Tex, however, KILLS IT! I've had to do irrigation work (flooded grass fields, trudging through drainage ditches) in them and it takes a whole lot of water to get my foot wet. I can be in ankle high water, not over the top of the boot, obviously, and stay dry for maybe ten full minutes of the boots being completely submerged. I've never experienced a better water-proofed boot. The leather does need TLC somewhat often. Because of the Gore-tex, you can't treat the leather with some more durable waxes (compromises the Gore-tex if you do) and you can only use an oil to keep the leather supple. With any leather boots, the leather gets brittle if you don't keep in treated, especially when working the boots hard.
This boot fits my foot particularly well. I have a size 7.5 foot, 3D wide (short and squat foot) and I've got the size 7 in this boot. The boot packed out pretty quickly and molded to my foot really well. This boot isn't made of super stiff leather so its able to take the shape of the user's foot well. All day comfort, for days and days on end. I can even run decently in them. Great boot. Danner is always top-notch!
