In reply to Delta Wolf:
Have used the Nepals for 14 hour long days that included trails, woodland, rock, scrambling, glaciers, scree, ice and snow (inc crampon use). Always found them to be very comfortable, versatile, reliable and robust. Have also worn them for several long days in a row with no problems.
That said, I usually have three-season boots or approach shoes available for lighter days to give the feet a break when the opportunity presents itself.
