I bought these sandals several weeks ago (REI) and have worn them a lot.  I had another pair of  cheaper Teva's for several years, and these are much more comfortable, and have a better fit.  The footbed is soft and comfy, but gives good support. The straps are lightly cushioned, which adds to comfort.  I prefer these adjust-once, then use click-togethers to put sandals on, rather than messing with velcro straps, which, over time can become less reliable and not stay completely closed. However, the click-togethers can be a little snug to pull together once you've gotten the straps adjusted to the perfect fit.
I've hiked some in them, walked through a stream, and just worn them around town---the fit stays right and they've always felt good. I'm not sure about the "water-drains-through" technology---sounds like a good idea, but it's hard to know exactly what these sandals would feel like wet, without it.  The soles do seem to have good traction, and don't get slippery when wet.  If these last, they'll be perfect for me.
