Replying to Boots worn down, popping out of skis randomly

After only a year of use, my Nordica Dead Money boots have worn down on the bottoms to the point where I am popping out of my bindings way more than I should, even with my DINs set to above where they technically should be. I obviously don't want to get new boots, because they fit me perfectly and I got them just a little over a year ago. I also don't want to continue to lose my skis when dropping cliffs and having to search through the snow for upwards of an hour to find them. Is there any fix for this problem?
