Regarding the material: these boots are very strong and resistant to abrasion and moisture. I hiked in these boots for 6 hours in terrain that was icy, snowy, slushy, watery, muddy, and rocky - a hike that would normally tear up just about any shoe. Yet, after all the bumps and plunges into sharp or wet ground, these boots stayed 100% dry (and warm despite the temperature being just above freezing with one pair of regular socks) on the inside, and were unscathed on the outside (aside from some faint water marks). There is creasing in the suede around where the toe bends, but it's hardly noticeable (and that just came about from walking in them regularly). The traction is also very good with deep, pointed and massive protrusions in the rubber footing (which seem like they'll take a long time to wear down), and a neat footprint on top of it all. I am VERY impressed with the material durability and function of these boots.

Regarding the comfort: Given that these boots fit me, they are very comfortable. Aside from the slight fatigue/muscle soreness that is to be expected with any long hike, I was very comfortable being in these boots for 6 hours in rough terrain (and I walk about 4 miles on sidewalks every day in addition). My feet never hurt after walking in these even for relatively long distances. They don't rub, and they don't cause any unusual pain or excessive soreness in any area. I will say however, if the ankle ties are too tight, they may rub on the outside of your ankle. Just don't pull the top laces too tight.

Regarding the fit: I am somewhat "narrow footed" in all measurements. This regular width boot formed perfectly to my foot, and has plenty of room in the toe area (which is recommended for hiking boots). I don't slide around in them (in any direction), and the ankle support is just enough to feel secure and not too restricted.

Regarding the style: They are somewhat clunky, but I think they have to be if you want the protection one needs when going on long hikes over rough/wet terrain (and in cold weather!). In my opinion, they are just the right proportion of fashion and utility (and I value utility more than fashion - these are not just for city trekking). So they do not appear as fashionable as some boots might, but the material is very solid, and very resistant to the elements. Also, the color is more like taupe than straight grey. I wear them with black all of the time though, and they don't clash too badly.
