Great shoes for rain and wet conditions, yet breathable for inside conditions
591213
I live in Southeast Alaska (natural rain forest) and people recommended these boots because they adapt to the wet conditions of the environment.  I chose this rating because it is my first pair of Keen hiking boots, and so far they have lived up to the high expectations that I have. I needed footwear that would meet all the different terrains in my city (rain, snow, slush, and rocky/muddy trails, asphalt/concrete).

I have a pair of  old and new insulated Xtratuffs rubber boots, but I like theses better.  Because they have great support.  The Xtratuffs are great for nasty conditions, but they don't have the support I need.  I am 6'5" and I need the extra support. I highly recommend these boots!

I have to say that these are some very comfortable shoes. They feel so light and airy on my feet. In the summertime, these shoes are perfect as they breathe so well. In the wintertime, these shoes are not so hot, as they breathe so well. It's a double edge sword.
These shoes are great, and I really liked how they made me feel. I felt like I had a spring in my step, as they felt that good.
The upper part of the shoe is all breathable material, so it is great for hot weather. Yes on the same side, bad for wet, rainy, snow, cold weather. That does mean that these shoes are not for year round use, unless you have really sweaty and stinky feet, and you need to let them dogs breathe.
They also need to come in more sizes, as the size range is limited.

I acquired this product at a discount for reviewing to give my honest and unbiased opinion.

I really like these shoes a lot. I have another pair of Columbia trail runners, and I bought these to wear for bad weather since they are supposedly waterproof. As other reviewers have said, they DO RUN SMALL. I ordered these in a 7.5 because of this, when I am sort of on the fence between a 6.5 and a 7. The 7.5 fits me quite well, and I can wear them with a thicker sock (although tbh, I wish I had ordered an 8!) These shoes have a rather thin form-fitting sole, and I feel a bit like I'm wearing a wrestling shoe when I have them on.
My main reason for ordering them was to wear in bad weather, and on wet trails. I'd hoped to be able to wear them in cold weather, but I'm not sure they will actually suit my needs if I can't wear a thicker sock. I'm trying to break them in a bit to see. However, I really do like these shoes, and wouldn't tell someone not to order them, just order at least one size up, and more depending on what your plans are.

Love these shoes. They are great for days when it's a little damp out but not rainy enough for wellies. I normally wear a size 10 (occasionally a 9.5, especially in running sneakers), but these 10s are a bit snug, mostly because of how narrow they are. I think an 11 would've definitely been too big, and I can still wear the 10s all day without too much pain, but do be aware that if you have wide feet (as I do), these may not be super comfy for you.

I like this shoe because it is good for running but not as good as running shoes, my feet feel the air because of the tiny holes which make it a breathable pair of shoes. The 1 reason that I didn't give it 5 stars is because when it is raining, my feet get soaked but this is mainly for somewhat warm weather such as summer time. It fits me perfectly and I am 12 years old and I got the size 8.5. Hope this review was helpful :D

Very comfortable, fits similar to same size ventilators.  Haven't tested waterproof thoroughly, but they have kept me feet dry in the rain.

The soles on these are great, durable and very anti slip.  Plus they make shoes that fit my 14 foot.  The toe box is wider than other competitors I have tried, Columbia for instance.  My foot usually fits 14m for most shoe types as long as the toe box is not too narrow.

i've worn these shoes twice now in the rain! they're waterproof and stylish, also less clunky as my wellies. the top is prettt tight so i do always have to untie the laces to put the shoes on and off.

I love these shoes. They are breathable and very "cushiony." Excellent for wide-width, high-arch feet; I have never had a shoe be so comfortable and supportive for my feet. Provides excellent support for fitness walking. Using frequently and they look brand-new still. Using on treadmill, neighborhood walking, and 5K walks.

Only drawback is that because they are so breathable that makes them somewhat porous in the mesh area and I would not recommend wearing these in the rain.  If you do, your feet will be a bit damp.

Excellent shoes!  Great tread pattern and well ventilated.  My feet get very hot and I struggle to find shoes with enough ventilation to keep them from becoming sponges.  The latest recommendations are to forego Gore-Tex type of shoes because the membrane cannot keep up with even a normal persons feet perspiration and to instead opt for a well ventilated model; yes, your feet will get wet but will dry much quicker.  Really it is probably a personal preference...with an Infantry background we utilized well ventilated over water-proof but some do not want to walk around for 30 minutes with wet feet.

Good cushioning and support, strings appear high quality and I usually struggle with fabric type of string loops (how the shoes are strung) but these appear high quality and durable material wise...I suspect that will be the first point of failure.

I recommend if you are looking for a well ventilated shoe with higher traction capabilities then athletic sneaker or a different look over sneakers.

They look great and fit well. I haven't tested the waterproofing yet. As for breathability, my socks do seem just barely damp after wearing all day. But they are comfy and have good grip. The shoestrings are long enough for double-knotting. It was nice to buy them on sale, too.

I love these shoes! As others have mentioned, they have a high back, which has been problematic with other shoes, so I was worried. But after a week of occasional wearing, that part doesn't bother me anymore. It just took some getting used to. The straps are long as others have mentioned, but not overly long, in my experience. I love that the shoes are waterproof. We live in the Midwest and it's rainy season right now, so I'm not worried about ruining these shoes if I'm out in the rain. I also have small kids who like to visit splash pads. I can just keep these shoes on as I chase around my kids without any issues. All in all, these shoes are lightweight and easy to wear, but they seem very sturdy and durable. I'll definitely order more when these are done for!

These shoes are fantastic for someone who wishes for a style upgrade from your typical rain boot. The shoe itself fits perfectly and is very comfortable despite not yet being worn in. Overall I give it five stars and would definitely recommend!

Updated after a couple of months of use--while these are wearing in very well and continue to be super comfortable, I'm noticing that my feet get extremely hot when I wear them!  I have stopped wearing thick hiking socks and now just wear a thin liner with them.  Given that, I should have ordered a half-size smaller.  I suspect the waterproofing has a negative effect on ventilation.

Original review below:

These are fantastic waterproof lightweight hiking shoes.  They provide a lot of support--my foot felt cradled as soon as I put them on.  They are also fairly wide in the toes, so I had plenty of wiggle room even with thick hiking socks.  The length seems true to size.  I did find that the heel slipped a bit at first, but I tried a different lacing technique and it solved that issue.  They were comfortable from the start and didn't require much in the way of breaking in time.

I tested the waterproof claim by stepping in and out of a few inches of water in my bathtub.  I wouldn't be standing still in water while wearing them, just crossing over small creeks and stepping in the occasional puddle, and I'm confident that my feet will stay dry.  I did give it a few seconds to see if water would start leaking in, especially around the seams, and there was no problem

Also, I think they're pretty cute.  I got the "canteen" color with brown and purple, and they go with pretty much all of my outdoor clothes.  They also work well with jeans if I want to wear something comfortable around the mall.  Mine have gotten a little muddy over the past few weeks and don't look any worse for the wear.

Great shoe for breathability... not so good if it's raining! I saw someone post that they're meant to be worn without socks. I wear them with socks and they're fine.

Update (Oct '15): I'm not sure when I wrote the original review, but I wore these things all summer and they held up great. The blue went on sale for about $70, so I picked up another pair for the gym and to wear next year. Although, I think I'll still get a lot more use out of the first pair (which I've put a lot of miles on; as a normal street shoe, a hiking shoe, and a gym shoe).  They're normally about $110 (and well worth it), occasionally a single color will drop to about $90 (a great deal), so I couldn't pass up $70 (yes, I've been checking in on the prices because I knew I wanted to purchase these again). Blue was not my first choice in color, but I went for it for the savings.

These are the closest things I've found to something that looks like a shoe but is as breathable as a sandal.

Hard to find a pair of shoes that are both waterproof and look good on a pair of nice jeans (or rather, don't look too nerdy like a pair of Merell Chameleons). These shoes handled the midwest winter really well and do great in Berkeley/Bay Area rain. The water proofing material is excellent but what really surprised me was the traction. The shoes are great for mild ice and do really well in morning snow. Never had a problem with water leaking through and they kept my feet warm on the coldest nights.

I would recommend changing the shoelaces because the shoelaces are very long and can get pretty wet.

I use this shoe strictly for walking at a specific place and for a specific time.  This is why I listed use at a couple of hours.  The shoes are not designed for wet weather use.  If you are caught in a rain your feet will be wet very quickly.

I do love these shoes, but because of my foot anatomy and issues with plantar fasciitis I need to remove the New Balance foot beds and replace them with orthotics.

Pros: They keep your feet dry when stepping into puddles, walking through snow, and walking through dewy, dewy grass.  They're comfortably warm without being over-warm.  After six months my 1st pair feels almost the same as the pair I just bought. The soul is sturdy without being rigid.  The ankle collar is comfortably cushioned.

I will definitely buy another pair when those I have wear out.
