That is a distinct possibility. That was part of the reason I was just wearing the gym socks. Now, these weren't super fitted mountaineering boots either so there was a bit of space but the Goretex socks were pretty tight. Like I mentioned, I just took them along since I knew my boots would be wet after a few days on the boat in Valdez. These were also some older Goretex hunting boots that had insulation as well. We mailed all of our gear home so we could bring fish back on the plane. I think it took 2-3 weeks in the mail and the boots were still damp when they got home and sat in the garage drying for another week.
Anyway, I like the PVC idea as well so I am hoping others give it a shot and report back.
