Thanks for the help, Kevin. What do you think about those fleece-lined neoprene things? It sounds like they are meant to keep moisture OUT, but in snow travel conditions, might do the opposite, plus provide some insulation.

Well, I'd like to avoid them, too, but the when the alternative is suffering frozen feet and even frostbite, it's a no-brainer.

I'd never heard of Trench Foot until last summer when my son's hiking partner on the PCT developed it after 5 days hiking through wet snow conditions just south of the Canadian border. He quit the hike and suffered with painful swollen feet for weeks!
