I'm thinking about buying a pair of Integral designs vapor barrier socks, mainly for showshoeing and winter hiking use.

Couple of questions:

1. Do they work - will they really keep my feet warmer in a less insulated boot, or is boot insulation far more efficient except heavier?

2. Should I wear them directly on my skin or should I wear them over a sock liner?

3. Should I wear a heavy wool sock over them?

Thanks,
