Has anyone on the forum used or played around with any type of moisture barrier systems in there boots to try and keep there socks dry and increase thermal qualities.

In reply to DeanD:
Yep. Plastic bags. Work great.

In reply to Skol:

until your feet get too hot and sweat and then you've wet socks anyway

In reply to goose299:

Not if you put the bag under your socks which admittedly can still be a bit grim.

In reply to DaveHK:

uurm trench foot please!

In reply to goose299:
See above. Your feet produce so much moisture that I doubt a breathable barrier would work?

In reply to DeanD:

I have been using insulated vapour barriers from rbh designs ordered over the Internet for over 10 years. These are much better than plastic bags. The boots stay dry and can be used the next day with minimal drying.

In reply to DeanD:

Used them quite a bit. Best if you have a thin sock under them - stops the slightly clammy feeling. Definitely needs to be well under zero.

The main benefit comes when you are out for multiple successive days as they stop the boot's insulation from getting ever damper from your perspiration. Your feet don't get too hot and if you use thin inners then you just have another pair to use for the second day. If you are away from civilisation for several days, the thin socks dry out quickly in your sleeping bag as they get damp rather than sodden.
