I am looking to replace my Technica Cochise ski boots. I noticed that all of the new boots seem to come installed with Grip Walk soles. Do these soles come off to fit regular alpine bindings? I have many pairs of skis, most of them with Marker Griffons. I am looking to buy a pair of K2 Revolver boots (similar to the old Dalbellos) - any thoughts on those? I mostly ski out West. I usually use my Shaggys Ahmeek 105s, K2 Pinnacle 88s, and on ice I use my Shaggys Brockway 80s.
