I've been wearing these shoes for a bit more than a month now.  They're very comfortable - the "cantilever" heel makes it pretty shock absorbent.  We walk a few miles each day, primarily on concrete or asphalt.  The wear has shown up, but it's reasonable wear.  I also wore them hiking in the Catalina mountains near Tucson.  They worked just fine on rocky trails.  I'd order them again!
