Ricethanks for all the response +k to all
Could you please expand on this. I mean I take out the liner to air them out every few days so that the odour doesn't kill people. And I wash the boot after the season is finished.
Am I missing anything else I could do?
Things on the "don't" list (in no particular order of importance):
don't leave wet boots in your car overnight after skiing (in general don't leave wet liners in the shell. Remove them, and let them air dry).
don't leave your buckles undone when storing your boots (buckles can snag, get twisted, bent, etc)
don't drag your boots when you walk
don't smash your ski edges into the shells (this will happen unintentionally but try not to do it)
don't throw your boots into your car/storage area
In general, if you think doing something might potentially damage your boots, just don't do it. Or at least ask someone if they think it's ok.
