There is nothing worse than cold feet that has been caused by of all things, sweaty feet. If the conditions are right and your choice of socks were not, you will end up with sweaty feet which will lead to cold feet in a hurry.
The best way to prevent this, other than proper foot gear, is to use an antiperspirant on your feet. Make sure to use a scent free product. You don't want the heat of your feet carrying the fhu fhu smell of your antiperspirant all through the woods.
