So.... lots of pros, and a few cons.
-The sole. Period. Super burly and stable on a bootpack, way grippier than any other snowboarding boot I've seen or used. It's still not as good as a plastic AT or mountaineering boot, but for a soft boot this is probably as good as it gets.
-Tours really well.
-Great stiff riding feel. Especially with the stiff sole.
-Hard for me to dial in the fit. I have lower volume feet, and this boot is obviously designed for larger/wider feet. It's a big boot. Yes I've heat molded the liners.
-Foot pain. My feet get banged up on long (over 8 miles) tours. Shorter tours are fine. I plan to add some custom footbeds to try and help this issue.
-The clip things that hold the laces are easy to pop off and lose.
Overall, I feel it's a bit of a sacrifice, but worth it. They are big heavy boots, but I really like the added safety and support for the uptrack/bootpack.
