    These are very nice looking and totally comfortable. Have not worn outside yet but as soon as I put them on my feet were happy. Color is great ( I got the blue). Fit is true to size. These will last. Well made.

    Love these shoes!

    This is my second pair of Keens and I love the fit and comfort. I was looking for a good comfortable pair of walking shoes with a bit of style and these did not disappoint. Usually I wear a 9 but had to return for a 9 1/2 as they were a bit tight in the toe. Keen has a seamless return policy so no problem.

    I will wear this shoe often. Very comfy. So far no negatives.

    Oh so comfortable

    I could just live in these. Although a bit snug at the ankle, I think they will loosen in time. I purchased them for playing sports in a pool to keep the bottom of my feet from scraping. They work great for this purpose. I checked out a lot of water type shoes before making this purchase, and Keen worked out the best.

    I race on sailboats all summer. This is the perfect sandal for the boat and all the activity under sometimes rough conditions, this shoe makes me feel safe and comfortable.

    Uncomfortable compared to other Keen shoes I've bought

    It doesn't look as nice in person as it does in the pictures. The color is fine, but the shoe is really clunky looking. The plastic square on the outside seems to somehow rub uncomfortably on the inside. I know that doesn't make sense, but that's where I got a blister. I am really disappointed as I have had several pairs of Keens in the past. I doubt I'll wear them again.
