This is the first pair of Keens' I have purchased. They won't be the last! This show was comfortable right out of the box and needed no break in time. I also purchased a competitor's show at the same time and these are by far the most comfortable. plenty of room in the toe box and comfortable on the sole. I have painful feet and it is hard to find a shoe I can wear for more than a couple of hours and so far I am wearing these all day.

I hiked over half of the Appalachian Trail in these, about 1100 consecutive miles. They have great durability for trail runners. The soles are thick enough not to feel every jagged edge of sharp rock I came across in PA, and the treads have enough grip to give me confidence on steep smooth rocky slopes in NH and ME. The tread finally started to loosen after about 950 miles, but they kept going with only apart of the sole peeling off. I haven't had a sudden blow out in the soles yet, and the shoes still don't have holes through them, although the interior seam by the heal is ripped exposing the interior now. Of course no shoe is truely water proof, but these do a great job when accidentally stepping in midsize mud puddles, walking through dew coated grass, or light ... MoreI hiked over half of the Appalachian Trail in these, about 1100 consecutive miles.

Of course no shoe is truely water proof, but these do a great job when accidentally stepping in midsize mud puddles, walking through dew coated grass, or light rain. When they did get wet, they dried in a reasonable amount of time, which seemed to be maybe an hour longer than the typical non waterproof mesh trail runner. (drying time depends on weather, degree of wetness, and outside temperature) My feet weren't any hotter in the Keens than in my previous trail runners, which were like sieves when it came to any kind of puddle. My favorite part is the large toe box. My feet swelled in width on the AT, and the other shoe brands had too narrow of a toe box for me. I tried 4 different pairs of shoes on the AT, but I ultimately could've done the entire trail in 2 pairs of these Keens. I intend to add 80 more miles to these shoes before putting them to rest. Of course not every shoe works for every foot shape, so try them out first! I might also mention that I bought inserts for these. I gave it 4 stars because nothing is perfect, but this is a great shoe.

I needed to replace my previous pair of Targhee's. These seem a bit heavier than a few years ago but the same stiff sole, good arch support and nice waterproofing. I prepared for my 2 wks long distance walking in the UK with good training, gradually increasing my mileage and going out daily. No problems with the Targhee's until I got to the UK and developed blisters with bruising on 3 of my toenails within 2 days on the trails. Only diffierence was more irregular terrain. This had happened with my previous pair and I had written it off to being a 1/2 size too small. I guess my feet don't like Targhee's. They also did show more wear on the soles than I would have expected with my 6 wks of training.
