I don't have any experience with those particular boots, but I can tell you that I have molded several alpine boots with a moldable liner. They truly to help the fit, and quite often depending on the liner people will move the liner from shell to shell over a period of time. (if the shell of the boot starts to wear and needs to be replaced) Some of the liners can be remolded another time, although perhaps not to the orginal quality... so that might be a question that you could ask when looking at boots. Sorry I didn't have the info that you were looking for, but hope this helps a bit.

Good luck in your search!!
