Does anyone ( Dane? ) has any idea how significant the ankle support gain would be with using a Baruntse inner boot in a Scarpa Phantom 6000? I bought the Phantom 6000 in spring and used in in Alaska this year on a lot of endurance ice ( Mt. Huntington West ). They where super warm, light and perfect in steep ice and mixed. They turned out to be complete calf killers in the 50 – 70 degrees blue hard ice part.
