Do your feet sweat so badly that even your dog avoids you? With the ‘Gravity Powered Shoe Air-Conditioner’ this can be a thing of the past for it will keep your feet at an ideal temperature. Incorporated inside the heel is a compressor-expander which is powered by ’gravity pressures’ placed upon the shoe when you walk. A network of heat exchangers, containing a low boiling point liquid, transfer this energy to the soles of the shoes and, depending on you’re mood, you can heat or cool your feet. Just be careful you don’t walk so fast that you get frostbite. <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" />
