    I have very tender feet and usually break my new shoes in over a number of days. Not with these put them on a hit the road, my feet were sore from the mileage, but not sore from the shoes...Keen another instant hit!

    Unbelievable!

    I'm on my feet all day working in a large garden center and these shoes are perfect! The elastic band at the ankle makes heel slipping non-existent! I took these out if the box, worked a 9 hour day, walking about 3 miles and didn't get a blister!

    This product fit better than the whisper. These will be great for water sports activities. When I can afford a second pair, I will get them especially if they have purple in my size.

    Definitely recommend!

    This sandal fits like a glove. No guessing about size! I wear them for daily walks and specifically for traveling to DC in the next month. I'll be on my feet a lot doing tourist stuff, so these really provide support and comfort. They're not horrible to look at, either. I love the lighter colors.

    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.

    This is my new go to sandal. I take it hiking and is a great sandal for fishing. I'm in love with them!

    Great shoe

    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.

    Exactly what I wanted!

    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.
