"My husband and I just came back from Alaska, where we flew along with the Iditarod sled dog race in our Piper Cub. It was one of the coldest Iditarods on record, temperatures were 20-30 below zero, and the plane doesn't have a real heating system. We often had to fly two hours or more, and there was no way to mover around to improve circulation. Had it not been for our Thunderbolt socks, we surely would have had frostbite. As a woman, I have had many items of clothing that I loved to wear, but nothing compares with your socks! I love them!"

With the increase of interest from women for our product, we are introducing our new women's styles.

These new kits offer all the same great options as the men's versions:

The basic Thunderbolt electric sock kit contains a pair of heated, high-quality socks coupled to a state-of-the-art battery pack. With a high-low power selection switch waist-mounted control box. The control box features a built-in LED which gives an indication of high or low heat settings and shows the state of charge of the battery. Also included is a 110 volt "smart" battery charger.

One cable from each sock is normally run up the leg between long underwear and outer pants and exits at belt-level. The cable connects to the controller/battery pack, which may be clipped to the belt on either side of the waist.

The battery pack is quite light, weighing just 13 ounces with carrying case and attached control box.

Liner Socks

We recommend a liner socks be worn inside the thunderbolt electric socks. This allows the user to wash the liner socks frequently and hand-wash the electric socks less often.

Any thin sock may be used as a liner, but we offer a high-quality liner sock especially designed to wick away perspiration. Our recommended liner socks feature:

1. X-Static silver coated nylon to help eliminate foot odor naturally.

2. Silver provides natural thermal conductivity to even out foot temperature.

3. Smooth, flat toe seam for maximum comfort.
