    These seem to be very well made and feel sturdy, yet with all the right materials. My only reservation is that they seem to fit about a half size too small for me. I wear 11 normally and these fit like a 10.5; not super tight, but I feel they'd get uncomfortable after wearing on bare feet for several hours.

    Too small

    The CNX is probably more than one size too small. I have to return the product. It's probably women's size.

    Know what this footbed is before you buy

    5

    When I first bought these, I had previously had a few pairs of newports. I was shocked when i realized that the footbed is very thin in comparison. Recently I have discovered that there is a fad going around called minimalism, or minimalist footwear. This is all about feeling the earth with your feet as much as possible. Once you discover this you can feel the perception in your brain and it is an amazing feeling. You can feel every root, rock as you are walking/running. Most people would ask why would you want that? But I'm telling you, that there is just something about ground perception. The footbed on CNX is very thin, but also very good. I'm no expert but I believe the thin soles on these can teach you how to properly walk on the front of your feet instead of heel first walking/running. I've had these for about three years, and they have held up pretty well with heavy use. I am disapointed in the very few current color choices. Overall this is a great sandal, I wish there were more color options for my next pair.

    comfortable, easy to order, and easy to size.

    These are awesome. I can order my size in any kind of Keen (steel toe work boots, sneakers, or sandals) and I get a perfect fit. These sandals were no exception.

    Great shoe: buy a full size larger than normal

    4

    Great shoe, very comfy and light weight, yet feels sturdy. Only reason for not giving five stars is they are sized very small. I had to return and re-order twice to get a size that fit me. I am normally 8.5 and even the 9.5's I ended up with are *just* big enough to be confortabke. Otherwise, an awesome shoe.

    So far so good

    4

    Good traction on wet rocks. Nice and light like a more traditional sandle. The rubber toe bumper is small but adequate for toe protection . Low profile so my foot fits under the thwart w less pain from the bulkier sandals. As a big guy a wide version would be great. Time will tell on how long the stitching & major stress points last.

    Awesome water shoes!

    I had a pair years ago that I loved, but they were chewed up by a puppy. I live on the water, and love these shoes!

    Comfortable and light

    4

    They are very light and comfortable as all three pairs of Keens I have owned. The only difference is these were very narrow and ran about 1 size small. Now that I've worn them for a week or so, I can get them on a little bit easier but they were tight the first few times wearing them

    Great Fit and Feel

    4

    Great fit and feel. This is my first pair of such sandals and I've been wearing them ahead of a couple of trips in which I plan to put them through the test with hikes to and from waterfalls, etc. So far they are comfortable enough and I don't expect any issues once we are out and about. The only drawback I will note is that I wish there was more arch support. These feel exceptionally flatter than what I am used to. Even my common flip flops feel like they have much more arch support.
