Electric Heated Socks

Need Electric Heated Socks to keep your body and feet warm?

This Thunderbolt sock heating system represents the culmination of over 20 years refining a practical method for staying warm outdoors on cold days.

Sock designer, Bob Williams, says he saw his first electric socks when he received a pair for Christmas in 1958. They were powered by two six-volt lantern batteries and produced good heat - for a short time.

But there was a major problem. Buying replacement batteries became very expensive for a high school student!

Fast forward to 1975: Realizing that a rechargeable battery was a must, Bob snipped the cord to the lantern batteries and devised an over-the-shoulder sling to hold a motorcycle battery.

At last there was substantial rechargeable electric power for the socks. However, climbing into a tree stand carrying this battery with liquid sulfuric acid sloshing around wasn't yet the perfect solution.

The 1980's, enter the NiCad rechargeable battery: At last on the market appeared a powerful, sealed, reasonably lightweight battery. Bob quickly bought a video camera battery and modified it to work with his sock heating system.

Unfortunately, a problem with the nickel-cadmium battery proved to be its "memory" effect. Unless great care was taken during the recharge cycle the battery soon lost a significant portion of its electrical capacity.

All in all however, the heated socks were becoming practical and easy to use. 1990, time to improve the key element - the sock itself: Believe it or not, the original 1958 socks (with occasional washings) had lasted until the 90's, when Bob retired them in favor of a redesign, with a larger full-foot heating element (most electric socks just heat your toes).

This proved to be more comfortable and passed more heat to the body through the circulatory system, so the idea was retained. In the year 2000, battery technology makes another leap: When the nickel-metal hydride battery became available, it offered a major advantage over NiCads: it greatly reduced the memory effect from recharging and allowed much more flexibility in using the electric socks.

No longer was it necessary to completely discharge the batteries before recharging; they could be "topped off" before heading for the woods.

2010 brings new battery technology: Lithium Ion battery cells significantly increasing runtimes between charges. The future: Since the Thunderbolt heated sock system is modular, improvements in technology can be incorporated as they become available. You won't have to scrap your complete sock system to upgrade.

Their electric socks heat your entire foot not only your toes! A practical system for use year round! Warms your whole body! Great for all outdoor activities including hunting and fishing and indoors for those with chronically cold feet.
