Insulator Insole - Air Circulator
AirCirculators help your feet stay more comfortable in all seasons. The insoles are made with aerogel, a material developed for NASA for use in space suits and space shuttles, and this innovative insulation provides a barrier against both heat and cold. The AirCirculator is specially designed so that as you walk, a pump in the heel forces fresh air through channels in the insole to provide a continous source of fresh air to the arch of your foot. This enhanced comfort design is built into an insole remarkably thin that fits in most shoes and boots.
