I think the Meindl Perfekt is about as good an all-rounder as you are going to find. It has enough flex to walk in all day, and enough support to carry heavy loads. Wouldn't be my first pick for coming down a loose rock section with a heavy pack, but I've done it several times.
I'm running Denali's now, and they are stiffer and not insulated. I can still cover ground in them, but it helps a lot to adjust lacing.
