Has anybody had experience with these heated soles in a glider:http://gerbing.com/Products/insoles.php* ? would it be better to get sock?

Some of these types of products have horrible reviews but these have good reviews on a retailer's website.

Most of the threads on heated socks are old and are about wave flying. My issue is that it’s often over 105 degrees F on the ground but after a few hours above 14k my feet get painfully cold and would like something that I can turn on later in the flight.

I’m thinking of powering these off a dedicated sealed lead acid battery as I think the newer batteries are risky: *http://www.youtube.com/watch?v=mlZggVrF9VI

I've used heated inserts in many situations. The advantages are no
increased bulk which is important for us with big feet and selectable
warmth. It's silly to be futzing with snow boots in the desert. Just
leave the inserts off until it gets cold then set them to the lowest "
feet not cold" setting.
