That said, I'm not sure you really need to wire up your feet to keep them warm. You might just want to try some socks that contain Outlast, a material that absorbs heat when there's too much of it, then releases it as needed. Works great for gloves, socks, that sort of thing. Wigwam makes a sock called the Outlast Hiker Sock ($11; www.wigwam.com), made mostly of Outlast and wool. These are pretty tall so should work well with waders. You can find Outlast ski socks, too, which would be taller than a hiking sock. Use them with a good liner sock that has some wool in it, such as SmartWool liner socks ($10; www.smartwool.com), and your feet should stay plenty warm without the need to carry a pocketful of batteries.
