I like to wear a wicking sock and then an insulating sock. And some folks
might have a roomy enough (should be danged near loose) shoe but lace the
ankles too tight.

I buy a couple of those little hand warmer pouches in sealed in plastic that
you tear open and agitate. I have fingerless wool gloves and slip on in each
glove to a butt (he he) my palm. Oh no, it doesn't do to have cold palms
(wayno started it).

I tried the electric socks and they worked fine during a living room test.
then quit. I returned them and had a duplicate experience. 'Course that was
years ago and I imagine the technology has improved some......

I understand the Army is experimenting with some SPANKING new technology....
