Beware Packout/LacesI had a pair of Xena's last year (I think the girl's version of the endorphins) and had a lot of trouble with the liners. When I got them, they were super tight and responded really well. As time went on, they packed out more than I've had any other liner pack out. I ended up having so much foam on the liners that they looked kinda goofy.
Then the rivets that held the laces broke. I wasn't yarding on them or anything, just tying them out of the way. I finally broke down and got some intuition liners for them, which worked a lot better, and were lighter.
This all happened within 1/2 a season of skiing them. Granted, I work for the hill so I skied probably more than the average person. Then, one day I noticed that the flex in my right boot had drastically changed. It was fine going up hill, but super soft on the downhill. The walk/ski mechanism had broken, and it would no longer lock into ski. I took them to the boot shop, and we sent them back to Garmont. Garmont has excellent customer service, replaced the mechanism in both boots, and gave me a whole extra baggie for the screws to screw in the soles. I'm still not sure if I'm going to keep them or not though. I've got a tele setup for BC so the AT kinda seems overkill.
