> Interesting comment about inserts: maybe given that Arc'teryx has also made some new touring boots, they'll hybridise something to make a walkable ski touring boot, or a skiable alpine boot!
Walkable skiboots already exist, and even the 'Ryx one is not too bad.
Scarpa used to make the Phantom 6000 with inserts, but stopped.
Sure, skiing in a proper climbing boot would not be nice. But at least in the alps, and Scandinavia you end up moving on relatively moderate terrain in deep snow. That's where skinning up would make a lot sense, and given the gently angle even skiing down on non-optimal boots shouldn't be a problem...
