Okay, after reading one of the previous reviews here on BC, I was a bit reluctant to try a pair of Arroyos but I'm so glad I took the plunge!
I wore these for about 5 days straight in sandy beaches, rock climbing, peabled uneven winding trails, and uneven cobble stone streets with hills here and there and lots of heat all over. The were very comfortable and proved to be very durable. I made the right choice since these have a more rigid arch platform than the other Keens. If you examine the different Keen hybrid sandals, some have a softer foam arch area which is good for water and walking but not as much for rocks or twigs digging into your foot. The Arroyos provided a bit more protection from jagged rocks and branches. No complaints here, however I might put in a more aggressive sole for more aggressive hiking.
I have to warn you, these do seem to fit a bit large. Let me explain, I normally wear a 11.5 or 12 depending on brand but with Keens, an 11 proved the best fit. I would definitely try some on in real life first! If not try ordering a half size to one size smaller depending on your arch. Now when I say your arch, I mean with weight. If you notice many people are one size by measure, but about a half-to a full size more with their body weight on their feet. Add in some swelling after 12hrs of hiking and you have a foot screaming for breathing room.
These Keens are outstanding in terms of versatility, durability and breathability. I've taken them with me on two different trips and they have faired very well. The tread on these was surprisingly agressive! They almost felt like I was wearing my boots. Not only was I NOT but my feet were 'in the nude'...partially anyways...and loving the extra ventilation.
The fact that they are waterproof was just 'icing on the cake'. I was able to take these kayaking, beach walking and even had to swim with them. I will say that if you are looking for a dedicated watershoe, the open-healed Keens made out of Polyester webbing (H2s) are better but these faired VERY well. These proved more for hiking, walking and the occasional H2O dip.
I would recommend them without reservation. Especially if it involves water and fast-paced outdoor madness.

I bought these shoes for hiking . . . broke them in around town and working out in the gym. Then on to a moderately strenous hike in Kauai . . . the first mile or so without socks was fine then the blister was awakened. The remaining 4 miles were a foot's nightmare. It didn't help that I got them wet. Over all they are great shoes just make sure you break them in properly and/or bring socks.

These are solid hiking shoes. I took them to Costa Rica and they performed marvelously. They have a rugged tread on the bottom, and the open lacing system gives them a cool sandal-hybrid appearance. However, before you purchase them, be aware of the following:
-- The "charcoal" color is not really charcoal, it's a dark green color. This is not apparent in the picture and a little misleading
-- They take a LONG TIME to dry once they get wet. The leather is waterproof and there is a neoprene sock material inside the shoe, which makes them more versatile when hiking in water or wet environments. But once they were submerged in water, it took them a good 2-3 days to dry out.
-- They run very true to size. I wear a 12 in almost every shoe brand, and the 12 fit me just fine.
In all, these are great shoes by a great company you can really trust in. Keen makes great shoes. If you're looking for a less traditional hiking shoe that is versatile enough to wear on the trail and off, this rugged sandal hybrid is for you.

excellent Keen Sandal / shoe vents well and sets up well on any trail condition used em last weekend scrambling to some climbs in BCC...hooks up well on the loose stuff and the toe nose offers superior protection that Teva's cannot.

When using them in the desert, they've been great. Well ventilated, excellent traction, the sole is firm enough so you don't feel every rock and jagged edge you step on. They are waterproof so they are extremely versatile.

However, I made the mistake of wearing them to the office one day. The sole doesn't like marble floors at all. Every step was accompanied by a loud squeaking sound. I'm not sure how they would respond to hard wood floors, linoleum, or anything other than dirt and marble, but I would avoid using them for daily trips to the grocery store.

The quick release for the laces holds up pretty well, but when you really have to move, they tend to loosen up a bit. To compensate for this, you can snip the plastic gripper, add an additional quick release slider, then tie off the two laces.

Overall, these are great. Just keep them outside.

these shoes came highly recommended to me by a close friend. his recommendation was absolutely on the mark! very comfortable even in really hot weather, durable even when wet - it is a great all-around outdoor shoe.

I have used this model for 4 moths without interruption; one day one lace left me and I have noticed that is the weak side of those sandals because of rubbing; are there laces made with strongest fabric?

My husband has been wearing these shoes non-stop for two years, so it's time to replace them. He absolutely loves them; he can hike in them and get them wet, and they are easy to slip on and off but stay on his feet well. Keen has changed their sizing in the past couple of years so we had to go up a size in this sandal, as we also did with the new Keen hikers he bought last year (compared to the same shoe a couple of years before). He has very wide feet and although Keen doesn't make these in a wide version, just going from a 12 to a 13 worked well for him. I agree that feet can get a bit smelly in these sandals, but I think that's typical in shoes worn without socks. He hasn't had a problem with the laces slipping or any squeaking noises on our hardwood floors.

I like the ventilation that they provide but the slide catches do not hold .. This requires stopping often to pull them tight..keen's remedy for this was to send me new slide locks and laces of the same quality.. This is a design problem.. My suggestion is to use slide locks like merrell shoes have .. They stay put.. If keen could improve this problem, these shoes would be great..

I HAVE 2 PAIRS OF ARROYO'S.. THE SLIDE THAT KEEPS THE LACES TIGHT IS WORTHLESS FOR WHAT IT IS SUPPOSED TO DO. THEY DO NOT STAY IN PLACE AND IT REQUIRES STOPPING TO TIGHTEN QUITE OFTEN.. KEEN'S REMEDY IS TO SEND YOU NEW SLIDES AND LACES OF THE SAME QUALITY! THE ONLY REASON I CONTINUE TO WEAR THEM IS THE GOOD VENTILATION . KEEN SHOULD TRY A SLIDE THAT HOLDS AS WELL AS THE ONE THAT MERRELL USES ON THEIR SHOES..

My first Keens were Newport H2s. A year of regular wear later they still look and feel great. My second pair are Keen Arroyos. I wanted to try the closed heel. So far they are great. I like the comfort and rugged balance of Keen. They maintain their shape. I got rid of my car 5 years ago. I walk a lot more miles than I had the will power to choose when motorized wheels sat at my door. :)

This my second pair in three years. The first pair is still in great shape. I wore them almost every day in all conditions. My wife just ordered her second pair for our two month trip to arizona.

I spend a lot of time in my Keen Newport H2's and wanted something that allowed me to use an orthotic insert. These fit the bill and feel great. I even wear them when I'm out and about for a short times in the Minnesota winter. A good pair of smart wool socks, and they are as good as the Targhee shoes!

Great hybrid product! I wear them everyday to work at a sea turtle center and the environment, needless to say, is wet and slippery. At work I wear them with short socks and on kayaking trips without socks and they're awesome with/without! If I get them completely submerged they usually dry out over night!

These are awesome shoes! I slip them on around the house, put socks on with them to go out on the town, hike in them with my puppy - whatever I want to do they do it!
I'm heavy and need good arch support and these have what I need. I'm going on a cruise in the Caribbean later this month and looking forward to using them in the water also.
Buy them!

This is the only sandal that I have found that has an enclosed heel. I have an orthodic insert that slips out of regular sandals. In addition, this is simply a great shoe to wear with or without socks. I am not sure that I would use them for serious hiking in the mountains.

Okey i purchased these shoes mainly because Ive had good luck with Keen products.I own the Napali,Newport and Newport H2...these however are a dissapointment because of the lace system that works awesome on other models.

I cant get these tight enough that when walking the heel part keeps flopping/rubbing (even tho the shoe size is deead on).Its like wearing a flip flop.The only remedy i could think of is to replace the locking adjustable laces to a traditional laces,add a real thick heel insole are or maybe even thicker socks.

I wore this shoes for 4 days leading up to my trip down to Moab, Utah to make sure I had the break in process going for when I was down there. I have a regular width foot, with a high arch and "regular sized" ankles and heels.
I normally wear a 10.5, but those were way to big, the 10's fit but there is a slight gap between my ankle and the back of the shoe. I did try on the 9.5 to see if that eliminated that space, but those were too tight.
The back, top part of these rub against the back of my leg and created some pretty bad blisters. I ended up putting large band aids over and continued to wear them thinking it was just a break in process issue. Down in Moab I wore them hiking around my camp site, in a stream to gather rocks for a fire pit hoping the water would soften them up and the rubbing would go away. After they dried out over night I put them back on, but still were rubbing, nothing I did seemed to make this go away and I ended up using my North Face trail runners to hike in on my trip.

These have been very durable shoes for me and unlike another reviewer I found them to fit to exactly the size I would normally wear (10). I've wear them frequently on all kids of surfaces - even sharp lava, and their not beat up. They've held up well in both fresh or salt water. I thought they would get trashed after salt water, but I just rinsed them off with fresh and they are fine.

I have one complaint that might be a deal killer for some: Unlike the other Keen shoes I have, these have a removable insole, and if you wear them without socks they make your feet sweat like crazy. You would think they would be very breathable, but I don't find that. When you are in and out of water it's not a big deal at all, but going around town it is.

i wear these shoes for my KingsCanyon tour in central australia where its extreme heat an roughed conditions prevale its a 3hr 6.19 ks walk so comfort is important these shoes do the job.

These are instantly comfortable, extremely durable and more protective than a sandal. The reflective threads help keep me from getting squashed by night traffic while pooping my black Lab. The only downside is the interior harbors a terrible foot odor and I don't think I've inadvertently stepped in my dogs calling card.

My first pair were great until I couldn't keep the laces tight. Try to hike with a loose shoe! I didn't read the reviews and thought the shoes were worn-out. Not so. The lace catch wouldn't hold. I tried to find lace replacements. No luck. Where can I find them?
I had already bought a second pair. I haven't worn them yet. Now I'm worried... If I could get new laces, I'd love these Hiking Shoes.

I have two pairs and ware them most of the time when it's hot or cold. They are very comfortable but laces need to be improved.

These shoes are great for hiking in warm weather, the ventilation is just amazing. It also helps when you have to pass through bodies of water, they dry out super fast. Very comfortable shoes, I wear them around town just as much as I hike in them. If they get too grungy you can just throw them in the washing machine, they are machine washable! Make sure to air dry them though, definitely don't want them in the dryer. Oh yeah, I would recommend going down a half size on these. I'm normally an 11.5 on the nose and an 11 would be perfect. You will not be disappointed in these as a hiking or casual shoe.

Feel good to knock about in. haven't taken them on any serious hikes.

So far the Arroyos have been very comfortable in all kinds of terrain. I've worn them in the water and on the street. At the beginning, they were coloring my toes black, but not anymore. They do make my feet a little bit smelly, but maybe i'm not used to going sockless.
