Heatsox 12 Hour Heated Socks
$US25, Hammacher Schlemmer
Doubling up on socks can only keep you toasty for so long in the current frosty conditions before the inevitable numbness kicks in. Could heated socks be the end to our frozen toes woes? The makers of these 12 Hour Heated Socks certainly think so.

A battery-powered heating element in the padded area of each toe has low and high settings, so they won't overheat and will keep your tootsies warm for 12 hours on low and 10 hours on the high setting.
