On many a spring day I've come home from an epic day up on the mountain only to find that my boots are nothing but a spongy bucket of sweat. On multi day ski trips, when you need to use your boots multiple days in a row, this is a huge problem. Those commercial boot dryers, you know, the heated cylinders, are interminably slow and you usually just end up with a hot spongy mess instead of a cold spongy mess come morning. Not a fun way to start an epic day on the mountain!
Well, my experience has taught me that airflow will do a lot more to evaporate water than heat. So, to get your boots as dry as possible, try using a little forced air instead of heat. The best way to accomplish this is to just grab a couple of case fans and an old AC adapter that outputs 12 volts.
Are you blowing into the boot, or pulling air out?
