The present invention relates to a shoe with a built in micro fan located on the shoe covering, such as above the toe area, to provide air circulation and increased comfort to the wearer. The shoe is preferably adapted with one or more improvements, such as a protective cover that protects the fan from debris and damage on the covering, a small rechargeable power source, and an easy to use on/off switch.
