  • I would buy them again

    Great the advice about 1/2 sizer was correct. I wear them all the time

    undisclosed

    I would buy this again and again

    5

    Extremely happy with overall fit, comfort and quality. Very happy with KEEN.

    undisclosed

    I would buy this product again in many colors!

    5

    These are the most comfortable shoes I have and I wear them every chance I get. I wish KEEN would make the other UNEEK styles in a true size 14 like this style. I also wish there was a light tan color in this shoe. They are very versatile and easy to keep clean!

    undisclosed

    Largest size is too small! Very disappointed!

    2

    I had to return these because they are too small. I really like these shoes but they need to be a half size or full size larger and they don't come larger. Come on, Keen, make these a bit larger and you would have a customer for life! I'm looking for a white pair for summer. If you get them a tiny bit larger I'm sold! I'd also buy a tan pair!
