I have a pair of Uneek O2s that I wear everywhere. The perfect summer/water shoe. I bought these hoping they'd be just as comfortable. Unfortunately, they're not for me. The footbed is not as soft (feels like a different composition) and so it's not nearly as comfortable. In addition, the sandals are more narrow than the O2s and just smaller in general. (I usually don't understand why reviewers complain that something is too small instead of just ordering up a size. In my case I'm at a 14; there is no going up for me.) Unfortunately, I waited too long to try these to know they weren't a good fit so they're just taking up closet space. Just found the new model (EXO) and hoping they fit more like the O2.
