Perfect for casual or business casual.  I've owned these for over a decade, and have easily worn them over 400 times.  They are still my most comfortable shoes.  They've never needed repair or had the sole replaced.  Only maintenance has been one leather treatment, and replacing the laces.  I had them professionally cleaned once and they actually came back MUCH lighter, but returned to brown within a few wearings.

My only issue, which made me drop a star (ideally half a star) is that the tongue slips.  It attaches at the very bottom and frequently slips off towards the outside of my foot, exposing socks thru the laces, which looks dumb.  But I'm not sure if that's the shoe or just because I'm flat-footed.

Still look great after 10+ years.
