Abstract
An insole having a molded base and a top sheet. The insole includes directional air ports for facilitating airflow above and below the insole. In addition, the insole has a shock absorbing pad positioned on the bottom of the base to provide cushioning to the area of the joints of the metatarsals and proximal phalanges and along a portion of the fifth metatarsal. A rear shock absorbing pad is provided which provides cushioning to the center of the calcaneus and which has an extension along the medial portion to provide cushioning to the talus. Two anatomical centering devices are provided on each side of the rear portion of the insole to support and direct the foot into the proper position over the cushioning pads. The medial anatomical centering device also provides additional stiffness to the arch area.
