And with bags on both sides blocking all air tmovement, those socks are fully effective as insulators.
It's a technique used by arctic explorers, to keep their sleeping bags and shoes dry. A vapor barrier inside the insulating material contains the moisture.
A thin base layer under the plastic will get soaked, but might be more comfortable than plastic against skin.
Another wind barrier outside the insulating layer, or even outside the shoe, keeps wind any precipitation away from the insulating layer.
