Glaciatorwrote a review of Alpina BC 1550 Backcountry Boot on December 21, 2010
I used these for quite a few years on an old pair of Trak touring skis that had NNN BC bindings and eventually got new skis (the Karhu Solstice XTs). I think these boots and the Magnum binding are probably overkill for those skis, but these boots have rarely let me down performance-wise. They tend to stay dry and warm and are very comfortable for any walking or hiking necessary.
My only complaints are that they simply do not cinch up tight enough for my narrow ankles and heels and the tongue shield doesn't help this either. I broke one power strap for this reason. The plastic loop the velcro strap passes through is simply too weak for how much pressure I put on it. They also can be a little too flat footed for me, so I should put in Superfeet or such, as hours of skiing can make the soles of my feet sore from kicking and gliding, but nothing terrible.
I would recommend these, but not without my aforementioned warnings. Also, I feel I may have bought one size too large, so this may have to do with any number of things.
