Runs small

Is a little small, I ordered a 9 will be returning and get the 9.5. They feel nice and light if you can get the right size you will not be disappointed.

Nice sandals

[This review was collected as part of a promotion.] As with most things I've gotten from Keen, these are comfortable and fit pretty well right out of the box. I'll probably size down half a size next time. Also, the little plastic clip that holds the elastic "laces" in place broke pretty quickly on one of them, but that's a minor gripe. I really liked the colors.

Great casual sandal

Love this sandal. I wanted something light for casual wear, rather than hiking. This is the model. Fits well, built well, comfortable and durable. Well done, Keen. I bought 2 pairs to replace older ones.

Almost Perfect. Runs small so size up

I have the Keen Newport sandals and I like them but I’ve always hated how goofy wide they were in the toe box. The Newports look clownish, quite honestly, but I like the style and quality of Keen. Enter the Clearwater CNX. These are a smaller, lower profile sandal so it doesn’t look like I’m wearing clown shoes. That's good. FIT: As many other reviewers have already pointed out, these run small. Knowing this, I purposely ordered a half size larger and they fit perfectly. They actually fit a little better than my Newports that are a half size smaller. So yeah, size up. QUALITY: Overall quality is on par with Keen. The webbing is robust and the rubber sole is rugged, not soft, so I anticipate tread wear to be slow. I also like that they still include the wavy razor cuts in the sole like boat shoes have for traction on wet, slippery surfaces. This is a feature that is often overlooked by many other companies and, as subtle as it may be, it sets Keens apart from the rest. The only thing I can point out that I don’t like (and this is probably just me being really nitpicky) is the thickness of the elastic draw cord. It seems a bit thinner than the one on my Newports. Hopefully they last with daily pulling on them to tighten. Other than that, I have no other gripes regarding quality. DESIGN: Comparing these to the Newports, the sole is not as thick and not nearly as wide. This is exactly what I was looking for. One peculiar aspect of the design is the rounded soles. They’re not flat at all so ankle support could suffer a bit. It would be rather easy to lose your balance or roll an ankle just walking in these. I’m sure I’ll adjust and adapt but it puzzles me why they went with this design at all. I love the Raven/Tortoise color and the quality of the webbing. The insoles are also comfortable and absorb shock. They're Keens!

Clearwater Sandals are not the Same Comfort

I generally enjoy Keen sandals. I currently own four pair. One pair has lasted 6 or 8 years and still going. This pair has been rafting down the Grand Canyon, on a two week trip to the Galapagos and on several hiking adventures. The pair this review covers is the Men's Clearwater CNX. These were to replace another oldest pair of Clearwater's. I ordered the same size as my other Keen sandals. I bought these in November when I noticed the color I wanted was available. This pair was purchased for some spring adventures. When they arrived, I put them on and noticed they were uncomfortable through the footbed area. I thought they just needed to "settle in". I didn't wear them over the winter until recent weeks. I am hoping they will give a little to accommodate my foot shape. My other Keen sandals did not need a wear in period, but the materials are not designed to give/stretch. The recent sandals do not use Vibram soles like my older ones. I am not sure if, or how, that change might affect the comfort. These are not the same level of comfort as my previous pair.

Use to be a great shoe.. no longer

Have owned five pairs of these sandals. In the past they’ve always been the most comfortable shoes. Ordered a new pair put them on and there’s no arches in the shoes any longer. Called keen to discuss the issue and they indicated that they change manufacturing facilities and haven’t gotten back to the quality they used to have. what was always so great about Keens was they had the perfect arch. Now there’s no arch and the shoes are horribly uncomfortable. Hope the correct this otherwise we’ll have to find a new brand.
