    Great shoe

    5

    After plantar fasciitis diagnosis, I needed a sandal that had some arch support and a soft insole for existing heel pain. Took them on a beach vacation and hiking around mountain trails. This shoe was so perfect for keeping me on my feet that I bought a second pair.

    Don't buy these

    I have never had such a horribly smelling shoe. I can't stand to wear them because of the smell and am embarrassed to be with others. My sports shoes do not smell at all. What a waste of money. And it's a shame since I enjoy wearing them otherwise.

    Real comfy, for walking around the city and I imagine for outings on the boat. And I like the color!

    Best sandal I have ever worn!

    5

    I wore these a lot this summer. I love the way putting on the shoe is almost like putting on a sock - nothing to bite or rub my foot. The size ran pretty true to size. I do find my feet get sweaty in these types of shoes, but I purchased a nylon footie sock (in both black and nude) to use with them so my foot has a little 'slide' factor for extra comfort. For me, I find these are the most comfortable 'sporty' sandal I've purchased from Keen.

    Best Sandal yet!l

    I have 2 pair ..... they are the best and I have had many Keen Sandals. Great for a walking trip. But be sure and size up at least a 1/2 size.

    The most uncomfortable sandals I've ever worn

    1

    I thought the removable footbed would be a cool feature but it turns out they make these sandals super uncomfortable. The insole is huge and takes up most of the space inside the shoe. I took the insoles out and the difference in fit was huge.

    I would buy theses Keen sandals again! They're super!

    I have probably 20 (yes, 20) pair of Keen sandals. Some are many years old and are used and abused almost every day. There's something different about the footbed in this pair of Keens. They are the absolute best! Wish there were so,I'd colors. I'd buy more!

    I would buy this product but size up at least a half a size.

    I wear a size 9 and that is what I ordered. I tried them on and they seemed tight, but wore them thru the house for a whil and they seemed to loosen up some. When I took them outside and wore them on a Walkman I started to develop blisters on my heels. I should have sized up a half a size. 😔
