Abstract:

The sliding-shoe sole is a device that is permanently attached or removably positioned on fitness shoes or the like. The sliding-shoe sole is fabricated from materials that reduce the degree of factional contact between the sole and a contacting surface. The sliding-shoe sole may encompass a portion or the entire bottom of the fitness shoe and portions of the heel, toe and side areas of the shoe. This arrangement enables the wearer to participate more fully in exercises and/or dances that require the foot to not only slide and/or glide along the dance floor or exercise surface along the shoe bottom, but also along the shoe heel, toe and side.
