    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?

    Hands down my absolute favorite sandal ever!

    Keen hit a grand slam with these sandals. They truly are like a second skin as far as the fit. You basically forget you're wearing them until you take a step and your foot is comforted by the insanely comfortable massaging dimples of the foot bed. Seriously the most comfortable sandal ever. Kudos to the flexibility of the sole as well. Truly is super flexible and supportive. They do require a bit of effort to get on but not enough for it to be a negative. Great job on these.

    Yes, I would buy them again

    All day sandals

    4

    I purchased 3 pairs to replace some 10 year old Newport's. In many ways this is the most comfortable sandal I've ever worn. The only reason that I didn't add the fifth star was that the back of the sock (rides on the Achilles) is a bit higher than my last sandals. It takes some getting used to. There is a pull tab on the back which buffers between ribs of the Achilles and elasticized sock material. That could be 50% wider. That said I wear these all day, they have good arch support and look great.

    undisclosed

    Fantastic!!!

    Super comfortable, and they feel well built. Definitely recommending to friends... love my Keens!
