Comfortable and breathable.  Seems to be durable.  I've put on a couple hundred miles and they show no signs of wear.
Easy to walk in.  the cleats don't click on the pavement or my tile floors.  I did quite a bit of hike-a-bike during a recent trip to Moab and the shoes were also very comfortable to walk in.  They are less stiff than dedicated biking shoes and I could feel the flex on my first couple of rides when I was mashing the pedals out of the saddle, but I got used to that and I don't feel any lack in performance from that flex.
I've always searched for bargains (sale/clearance) when it came to biking shoes and was never completely happy with fit or comfort.  I'm glad I paid extra for these based on the reviews.  best pair of biking shoes I've owned.
