Positive Reviews:

I love Chaco's. I found the best fit is to do the next size up and to be wide. The regular is a good fit only if you have narrow feet. Wide is good for regular width feet to actual wide feet. So, for me I am a size 7- 7.5 in regular shoes, I order Chaco’s size 8 W. I’ve broken in a couple pairs, so I recommend for a fast break in period, use them in water a lot, and at first walk around in them as flip flops ( w/o the back strapped up), this allows them to get broken in the foot area. Once that is broken in the heel area should break in just fine. Yes, it's an art to breaking in a pair of usually expensive Chaco's, but it is worth it (to me) to have a lifetime sandal, that is good for hobbies and town wear. Chaco’s last me about 6 years of regular summer wear, then the sole kind of starts flopping off. You can get your sandals repaired through Chaco and probably get another 6 years out of them, but I usually see it as an excuse to get a new pair :} Also... I just ordered a customized pair off the chaco website (pick all your own designs, sole and color, stitch color etc) for 130 dollars. Compared to retail stores you have limited selection and they cost about 116 dollars. I say create your own pair!!

After trying both the Keen Newport H2 and the Teva Tirra sandals, I have chosen these to be my sandals for backpacking around the world. I have extremely narrow feet, so the fact that you can adjust all the straps is AMAZING.
I wasn't crazy about chacos color options, but I ordered the Foxy Green and I LOVE it! I love that these are more sandal like than both Keens and Tevas and that there arent laces or velcro all over the shoe like Tevas and Keens.
You definitely have to break these shoes in, the straps rubbed in a couple places after I walked in them a lot, but they dont anymore. I also got a small blister on the bottom of my foot from the arch. I'm so used to wearing flat shoes with no arch support that after walking around in these shoes for two days straight the arch was giving me some foot pain and rubbing in a little blister. Again, this is something that has gone away now that I have broken them in and adjusted to them.
Overall they are the BEST possible option in both fit and function. I really don't think there is anything better out there. Chaco has officially won me over :)

I <3 my Chacos!

I absolutely love this pair of Chacos! My previous pair lasted 9 years and were finally rendered irreparable due to an epic hike near Big Sur, CA. At least they went out with a bang! I loved them but since it's getting close to winter I didn't want to buy a new pair right resolve lasted a week. When I found this pair I was SO excited! I have yet to wear my new pair for a hike, but I have no doubt they'll stand up to punishment when I do get out there. I wear them to work, walking the dog, etc. The arch support is great, they're definitely durable, and I love their weight. I honestly can't think of anything bad about these sandals, except that if you aren't used to Chacos they do take a little getting used don't break them in, they break you in. These are my favorite sandals and I look forward to spending the next 9+ years with them.

I bought these as a birthday gift to myself. I live in Florida and I go to the theme parks a lot. Flip flops and sandals just weren't cutting and sneakers get too hot in the summer. My cousin had a pair and she swore by them. So I got a pair and I am so happy I did. I wear them everywhere. I also have flat feet and bunions and they don't bother at all. It took some getting used to and you definitely need to break them in. But once you do you won't regret your decision. I am 27 and I have feet and lower back pain issues since I was a teenager. I have never found a pair of sandals that were so perfect for my feet. The biggest plus is they have great traction, so no slipping or falling on wet surfaces.

Love these things

I've had these for a year or so now, and I love pretty much everything about them. I have wide, flat, and generally unattractive and usually uncomfortable feet, and these are great (people even tell me they're cute!). It did take a little while for the straps to quit tightening up, but now I almost never have to readjust them. I have enough space in them so when my feet swell up a little in the heat, they're still comfortable. I've never had a blister from them. They're great for hiking, biking, splashing around in the water, running errands, hanging out... the only (and I mean ONLY) thing I don't like them for is kayaking - my heels rest a little uncomfortably against the bottom of my boat. Other than that, these are good for everything, and they look as good as the day I bought them.

Happy Feet!

I really do love my Chacos. It took me a while to get the straps adjusted just right and then they were a perfect fit. The only bummer is that the straps move after I wear them for a short while. The movement of my foot while walking pulls the straps around my toes really tight and a slight adjustment needs to be made. This might be a pain for someone else, but I don't mind. It's an easy adjustment and takes only a second. Other than that, they are one of my favorite pairs of footwear! I've been campoing and hiking, wear them to work, out with my friends. They are good to my feet and are super durable. If they are dirty, I can just hose them down and set them to dry. I'm saving up to buy my second pair!

Great support

Got this at an REI returns shelf. I usually wear a 7 1/2 w, so I got the 8w. They fit perfectly. I went up so that they were a little loose at the store, but are still comfortable after lots of walking. Hiked 7 miles around Castle Rock State Park with out any problems besides dirty feet! With knee issues good support is necessary and most of the time sandals that is hard to find. These sandals give me so much support that hiking significantly uneven terrain did not cause me any hesitation without a knee brace.

I will never go back to a different brand of sandals!

They also go from water to shore well. They dry fast and don't retain any lake smells that might be unwanted in town.

My wife had an old pair of Chacos that didn't fit anymore because her feet flattened out a little when she began running a lot. We replaced them with these in a size larger and they fit like a glove. She wore these around camp and hiking in Banff for 10 days shortly after she got them. They were a little hard on her feet at first but now that they're broken in (for the most part), she'd wear them all the time if she could.
Be aware, that Chaco's are heavier than most other sandals you've worn and they can be quite painful on your feet at first. But give it some time and they'll mold to your feet and you'll get used to the weight!

I love my Chaco's. My daughter has had a pair for the past 2 years and practically lives in them - in and out of the water. She always told me they were comfortable.
I have problems with my (50+ year old) feet so I have been to the doctor for inserts and expensive tennis shoes to wear all the time.
My feet feel better and I can be on my feet longer in my Chaco's than in any special made shoe I have had. I just recently ordered a second pair. I plan to live in my Chaco's during this summer. They fit my feet like they were made special for me. Enjoy!

Amazing sandals

My boyfriend had a pair of chacos and finally convinced me to get some and they are incredible! You need to wear them around a few times to break them in before taking them on any long journeys, but they're incredibly durable and comfortable. I would recommend the Unaweeps over the Yampas since you can get more versatile use out of them: you can wear them around the city or on a backpacking trip without having to worry about enough traction and durability. I usually where a size 7.5 but since they don't have half sizes, I got 7s and they fit perfectly.

Slippy Straps

My wife got these because she wanted a good durable water sandal. I have a pair of the the single strap Chaco's that I wear all the time and love for a variety of activities. Apparently Chaco's are cute and popular and hard to come by now. Thanks, fashion! Anyway, my wife liked the liked the look of the double strap. They are admittedly more feminine than the standard Chaco's. However, the straps would never stay in place and continually cinched down on her toe. She returned them and opted for the classic single strap. I presume they will work better for her as the wide strap provides more friction, but we are still waiting for a pair to arrive from Salt Lake City. Thanks again, Fashion!

I really Tried

I really tried to like this sandal, but my feet didn't well for it. I walk with my toe up and because of that it made walking a long time in the shoe hard. THe other thing I noticed is that the sandal continues tightening up. Every day I had to loosen the shoes up. I switched over to the chacos without the toe loops and I really like them. I can hike and walk around all day with them. They are great sandals but just be aware of the toe loop thing.
PrincessLeaJediKnight at REI on 07/07/2011

The straps, even when adjusted, didn't fit and my feet were sliding around in them - they were just too long. I heard that they will fix this problem for free if you send them in, but the other problem I had was that both of my feet wouldn't stay centered so I was walking on the lumps on the side and it was very uncomfortable. I think they are great for people with wide feet, but not for people with very narrow feet!

Adjustable : (

I bought these because the straps are adjustable for a custom fit. My feet are slightly narrow and many sandals are too wide. But the straps don't stay as adjusted and keep getting tighter in some spots. I readjust the straps every hour or two. It's getting worse, so I will be returning them.
