There is a machine they do "heat mold" with. Its basically a heater with a fan/snout that the boots fit over. They run the heater for about 10 minutes then have you step in with the toe of the boots on a piece of wood. Basically its hot but you stand there for abit and then you can feel the molding process.
I dont see any on the east coast. Not to say some locations dont have them. But when I bought my boots out west thats what they did.
I know they do it in Zumiez at the Carousel mall, and I want to say they do it at The Ski Co., but I'm not certain
