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.
