In summery, keeping ski boots dry is an important factor for ski boots lasting. This is what actually I have understand through out the conversation.Cattracks, yes. Liners will go first, if cattracks used. 500 to 800 days, depending - at least. But that is the shell, not the liner.
In a humid area, or skiing every day for long hours, drying boots can matter. In a dry climate, every other day, often half days, not so much.
I just bring them into the relatively dryer house overnight in winter - heating dries the air out. And that is all that is really needed.
(I ski every other day, not every day - if every day, depending on inspection, I might pull the liners sometimes, on wetter days, maybe. But no need now.)
No matter I store or use everyday, I should dry my ski boots after every ski season.
