    I have previously worn the 01 uneek shoes with mixed feelings, so-so on comfort and a show stopper when I get a piece of little gravel inside. Seems walking at least for me kicks up the gravel and small bits sometimes get inside.

    ANYWAY the updated one there is no such problem. I live in Bermuda and on an island there is a lot of sand. I am frequently in the salt water with my dogs and these shoes are the best so far. really easy to slip on and very comfortable. When I walk in the water I can easily swish the sand out, they are easy to swim with and then walk home after. I love them!

    I have several styles of Keen shoes, sandals, and boots, and I wear them constantly -- all favorites; but this style didn't work for me. I really wanted it to work because it would be a perfect summer shoe, but there were too many problems. They run a bit short as advertised, but that wasn't the fit issue; this shoe is just very tight (has a continuous closed "sock" at the opening) and doesn't have any give (for flat feet, it may be okay). The shoes also seemed to have very little arch support in the sole and at the same time had that support on the outer edge of the sole (opposite of the arch), causing the foot to sag inward such that the shoes rubbed on the inner side of the heel -- in just a few steps I could feel blisters forming. A larger size would've been too long and resulted in more slippage/rubbing. Usually I won't rate low just for fit, but these fit issues are so weird.

    Comments about Women's UNEEK O2:

    Because I live in Utah and I bought these sandals in December, they'll have to wait till Spring/Summer to be tried outdoors :-) They feel great when I tried them on indoors though, I'm sure I'll love them outdoors as well. The only con I noticed is that, toenails have to be trimmed pretty short or else they get stuck in the webbing around the toes.
