Positive Reviews:

I'm a relative newbie to the Chaco scene; I've been wearing my first-ever pair for the past year and a half. I was hesitant when I first put them on; the very prominent arch tempted me to send them back. I'm SO glad I didn't. After the initial break-in period (a week or so), the sandals get a nice better-than-barefoot feel. The fit is so very customizable--which comes in handy on long backpacking trips when one's feet start to swell. I take an 8.5 or 9 in trail runners, but the Chaco women's 8 works for me. I've learned to keep them nice and loose, and I don't have to worry about chafing or blisters.
I wore these nearly every day for four weeks this summer while walking el Camino de la Costa across northern Spain. That's 20 to 30 km a day through mud and mountains and city streets, in July heat. They held up well and gave me a killer sandal tan (far superior to a sock tan). The straps dry fast and there is no velcro to wear out or get gunked-up. The Vibram outsole grips like a dream.
My only wish, being a bit of a flat-footed supinator, is that Chaco would come out with a lower-arch version of these. I know I'm a minority here; most people lap up the arch support. Plus, after months of regular wear, I've flattened out the footbed so that it isn't so much of an issue. They still get 5 stars, because there is no finer footwear on the planet. Too bad they don't let me wear open-toed footwear at work.

This shoe is top notch, I love it! I were my chaco's everywhere! They are like my best friend. Some people don't like the arch of the shoe, but I love it! It helps me have better posture and it almost feels better when I walk.They are wonderfully price for their quality. I am one to talk, I have 12 pairs of all different kinds. I do not want to let go of any of them, not matter how ratty they are. Chacos get old like any other shoe, but that just shows how much they have been warn out. My friends will ask, " Why won't you get rid of a pair?" i just say "I have broke them in, and I love them soo much." I think I am obsessed with chacos. I will go hiking with my friends in them, swim in water falls with them, shop in them, walk in them, you name it. Chacos can do anything at anytime, any where.

Performance is right!

I bought my first pair of Chacos 7 years ago, and am still wearing that original pair today. They classify these as performance sandals, and performance is right! The sticky Vibram soles are great for moving around on wet rocks (normally a guaranteed ankle breaker for me), and the fully adjustable strap system means I get the perfect fit everytime. I wear them loose when I'm at work or around town, and tighten them up for hikes. I really cinch them up if I'm crossing rivers or rockhopping. On top of those great features is probably my favorite: the arch support. I've always had trouble with my feet, and used to have to wear orthotics. These are the only sandals I have ever found that provide the kind of support I need. Oh, and did I mention the awesome tan? Chaco wearers can always recognize kindred spirits by the cool Z-shaped tan you get when you wear them all summer.

Best sport sandal on the market!

I can't say enough good things about the chaco Z/1...these sandals rock. I literally live in mine when the weather's warm (and sometimes when it's not). They have great support, and NO VELCRO to wear out! My old velcro sandals (I won't name names) used to get gunked up with sand at the beach, and generally would just wear out quickly. After a while the velcro simply wouldn't stick so the sandals wouldn't stay on my feet. Not a problem with Chacos. They are full adjustable, so they'll fit almost anybody, and they last forever. I'm not crazy about having something around my big toe, so I prefer the Z/1 over the Z/2. I have a pair of the flips too, and love them just as much. Highly recommended.

I wanted a pair of non-slip, comfortable sandals that were fairly rugged for hiking/walking on wet surfaces.... but I didn't want the toe strap thing.... I ordered these, hoping they wouldn't be floppy or loose. They're WONDERFUL!! I wore them on a trip to Costa Rica - pretty much for the entire time (except when we were DIRECTED to wear closed toe, high boots because of certain little poisonous critters slithering around....) They get tight by the end of the day, but I can easily adjust the straps and wiggle around and they're fine! I also LOVE (and did not expect) the feature of never really having to re-buckle them-- you just loosen the straps, slide in, tighten 'em up and take off!!!

Undoubtedly the best shoes I ever bought

I bought my Chacos about five or six years ago in a hole-in-the-wall outdoors store, and never looked back. Even with above-average wear, they still look like they're brand new. I have higher than average arches, and most shoes begin to hurt after a while, but these never hurt my feet. Ever. They stay in place and don't shift like a lot of sandals I've had, not even in water. They dry quickly, and are exceptionally easy to clean. The multi-adjustable straps are so brilliant that I'm amazed no one thought of it before. Once you've put them on, you'll never buy another pair of sandals again, until about 10-15 years from now when you've worn these out and need new ones.

I love my Chacos! All four or five pairs of them! These are just as reliable and comfortable as my others. If you need great arch support, these are the sandals for you. They are the only ones that I have found that are sufficient for my arches without any add-ons. This orange is a deep orange verging on red, which makes them a good match with either color. Also, I love how I can throw these in the washing machine. I wear them to a variety of places, business to the ranch and lake. Wash them and let them dry for a couple of hours and they are just like new for me.

These are great sandals. At first I was skeptical about the style in general, but decided to try them out as I had heard only great things about them. As a person with flat feet, the sandals were extremely uncomfortable at first because of the great arch support. However, they are much more comfortable now that I have broken them in. The black adjustable strap on the ankle does not look as ridiculous/long as it does in the video (on my feet at least). It is annoying when sand/gravel gets stuck between my foot and the sandal, but it's worth it. Very durable adventure shoes! Glad I made the purchase.
Katelyn K - customer at on 03/22/2012

Got these for a killer deal on SAC and love them! I wear them hiking, gardening, in the river, to the dog park, or just around town. They're support is unmatched by any other sandal I've ever had (aside from my several other pairs of chacos). They are well-made, love the vibram soles on these, because I know they will look the same after five years of wear as they do today. I am usually between a 5 and 6 in chacos and other brands, but sized down to a 5 in these. Don't hesitate to buy these, you will wonder how you lived without them when you get them!

Laura Burt at on 05/10/2011

Size: For athletic shoes I typically wear a men's 11.5 since women's 12.5 are hard to come by. For casual/dress shoes I wear a women's 12. With these sandals I could use the extra half size but since Chaco doesn't do have sizes I think they'll work fine (definitely better than a men's 12 which is huge on my foot).
Purpose: I bought these sandals for an upcoming trip to Mali, West Africa. I was told that for everyday and hiking, sandals are the way to go because you can just kick the sand out rather than having to constantly take your shoe off and dump it out.

Not a Good Fit for Me

My husband loves his Chacos, which made me want to have a pair; however, they are not a good fit for me. I have to continuously tighten the strap. The portion across the toe loosens, causing me to trip on the tip of the shoe. May be something unique to me. I normally buy wide shoes but these wides may be a bit too wide.
