I climbed ice in my ski boots yesterday, and had big problems with my feet when going over the lip from the steeper parts onto shelves. When actually on the close to vertical parts I had no problem seeing and placing my crampons, but with my ice axes on the shelf I couldn't hang back far enough to see my feet and with the ski boots I couldn't flex my ankles to get the front points into the ice without kicking the toe part of the boot into the ice and skidding off. I resorted to just taking huge steps to get around the problem but it's not that elegant of a solution.
Any advice on this beyond get real boots? I might be placing my axes too far in but I don't want to hit the convex ice on the edge.
