    If I had "normal" feet, I have kept these in a heartbeat. They are SO COMFORTABLE right out of the box. However, I have foot issues that require me to have a pretty good arch support. Most of my other Keens (I have MANY) have that, but these tend to be considerably flatter. Was hoping my orthotics would work in these, but the shoe was not deep enough. This is a very different design for Keen, but it's worth keeping around because of its comfort...and also cool look. I got red. Sad to be sending them back. Thank you for your wonderful customer service, Keen!

    I have 2 pairs of Uneeks, leather and H2O. I bought the first pair based on the same size as all my other shoes. They are so uncomfortable I can't wear them. I still loved the look, so I thought maybe a half size bigger would work. I was wrong. The problem with the shoes, or my feet, is they need to make these in Wides, bottom line.

    Comments about Men's UNEEK O2:

    I have a pair of the strapped heel and I love them I live in them in the summer. I wanted another pare of a different color so I decided to get the closed heel. My only complaint is that on the closed heel pair the sides or more open than my strapped heel which allows my little toe to pop out. Not sure why the difference since they are made on a machine so they should all be the same.

        Great looking shoe

        Comments about KEEN Men's UNEEK O2:

        I saw these shoes on a guy at the airport in Phoenix AZ and followed him until I could see what the brand is. They are a great looking shoe and I wanted to get my husband a pair for Christmas. They are light weight and have a unique look to them that I love. I gave this a 4 star just because my husband has not recieved them yet so I can not speak on their comfort at this point.
