I've been day hiking in Tevas for the past two years and they've been great for moderate distances (under 7 miles).

My feet sweat a lot. When I wear boots, my socks are always soaked within a few miles. When I wear Tevas, I don't wear socks and my feet stay dry.

Like any shoe there are places that rub. I had sore spots where the straps connect to the sole, but moleskin (and later calluses) took care of that.

I haven't done long distances or inclement weather in them yet, but I've got some longer hikes planned this year. I'll post my experiences with them.
