Replying to Full Tilt -- Heat Mold Liners

This summer I bought a pair of model A full tilt boots (not with the model A liner, it's the pro model liner). They're great boots and the guys who fit me were pretty knowledgeable bros but the heat molding process was a bit...flawed. My left liner fits well but they actually burnt my leg (through a ski sock) and my right leg was fine but the mold is a little bit screwy. It puts a little extra pressure on my shin and isn't as snug around my leg. I didn't actually notice this while at the shop cuz I was dying to get out of the scalding hot boots. Anyway, my question is, can the liners be reheated and molded again? Any tips for the molding process?
