I've got the Denali XT, and I've hiked 5miles one way in them, worn them all day, skinned, and cramponed with them and in no way do they not hike or skin well. No, they aren't sneakers, but they'll work without pain. If you want to ski, get them and don't look back. If you want an approach setup to technical climbs, go with the Silvys and mountain boots. Remember, mountain boots don't ski worth shit.
I don't know why people keep complaining that big AT boots don't hike; they do, and quite well.
