It is unlickly you will find a boot which will work well in the back country and the park. Those to aspects have very differnt requirments. Park boots need to be strong, and backcountry boots need to be light and have the ability to walk in them. Unfortunatly the more moving parts for things like walk modes mean that backcountry boots wont really be durable enough for the park.
You will have to scarfice either durability in the park or performance in the backcounrty.
