Abstract
An improved insole for a shoe comprising a plastic injection molded insole conforming to the shape of the foot and particularly the heel wherein a first oval cushion (typically 3 to 4 cm in length and 2 to 3 cm in width) of soft rubber is centrally located in a corresponding oval opening in the heel region and an optional teardrop shaped second cushion is attached to the top of the injection molded insole in the metatarsal region. Such an insole reduces fatigue, particularly in the case of prolonged standing.
