I've skied both a Solomon quest 120 and a dalbello lupo.
They are both strictly alpine boots, with walk modes. That being said, never have had any problems with the walk mode while skiing on them, for either boot. The dalbellos ski better, and that might just be the boot, but while pressing on the tails really hard, I can't tell the boot has a walk mode. In the solomons, it wasn't ever sloppy, but the dalbellos do feel better.
Summary: It's chillin. Full alpine boot with a walk mode. Burly shit. Get stoked.
