I have similar horizontal abrasions from the upper rim of the skate rubbing up against my ankle. I think I may just wait for my ankles to heal and then perform that heat mold correction. As far as subbing out to the LS2s, I think that would be a big mistake when you realize the CXN was specifically engineered for the skate. Like the other poster stated, you are better off getting a different profile. The Makos are profiled at a 9' radius so you can tinker from there with a reprofiling.
