Yeah, i sometimes still glance in here (it's spring snow and ice season out here in the Rockies...

). I just got myself a pair of Scarpa Magics for skiing. They come with custom liners. I've had a little bit of a problem with the fit, but only because they don't make the Magics *quite* small enough for my feet, so my boot fitter had to do some weird stuff to try to *make* the boot smaller (and of course the liner expands into the shell, so...). It being spring, I haven't had a chance to take them out in ultra-cold conditions, but I wore them on top of the Continental Divide at Loveland ski resort on closing day, and my toes were pretty toasty. I'd say they are definitely toastier than the standard liners in my Koflachs (tho' they were a dorky variety called the "lady soft viva," and I don't think they're as warm as normal Koflachs). As I said, I haven't tested them in *truly* cold conditions, but just cuz it's spring doesn't mean it's always warm here in CO, and so far they've served me pretty well. The weight factor definitely wins points with me too, since I'll be using these boots (hopefully) primarily in the backcountry and the less weight the better for going uphill! Of course, YMMV since you're talking about Koflachs instead of ski boots. But that's my .02, for what it's worth...
