    Great shoes, I wear them everywhere. I had problems with another brand not having enough support for my feet. I can wear the Keen Evofit One all day without a problem. Thank you

    Ultimate summertime all around sandal

    5

    Everyday summer time use. Fits like a sock, super comfortable and not as bulky as the newport's, though the newport's are awesome too.

    Wait...are these Keens?

    Lightest best fitting and most comfortable sandal I have ever owned! Almost want to wear them to bed!

    The Most Comfortable Place My Feet Have Ever Been!

    5

    I purchased these after months of deliberation. I had an old pair of Clearwaters which had been my go to summer shoe. My new ones had to be as comfortable but with a thicker more comfortable sole. I swung backwards and forwards between the Newport and the Uneek, but none of the colours really spoke to me. Finally I ordered these and as soon as I put them on, I knew it was the right decision. For the first day, they felt very snug, like a new pair of slippers. The achilles strap took a little getting used to as its thicker and higher sitting that the Clearwater. After a day or so, they gave slightly and now I can't stop wearing them. Seriously, I look forward to being off work so I can wear them. They are a bit heavier than I thought, in fact, they're heavier than my trainers. But don't let that put you off, as once you put them on you quickly forget you're wearing them. It's safe to say, I am really happy with my Evofit One's. They helped get over the loss of my Clearwaters - and that's got to be a good thing.
