I've been wearing these shoes every day for a couple of months now and I love them. I have pretty bad knees but I spend a lot of time wandering aimlessly around my town and in the woods (on trail/off trail/scrambling) and have had no real issues. They have great support and are incredibly comfortable. The traction is outstanding (as is that of most Vimbram soles). I feel confident at the crag whether I'm working near the edge building a top rope or if I'm loading a sketchy rappel. And as a bonus they look good too.
I highly recommend this shoe.
