  • Patent number: 5491909
    Abstract: A shoe for use on a post-operative, traumatized, diabetic or insensitive foot includes a shock absorbing sole material, with an insole of shock absorbing foam that contours to and supports the sole of the foot, and being regulated in flexibility by a metatarsal shank that limits the amount of flexibility under the metatarsophalangeal joint to provide controlled support to that area. This sole is of a special rocker design that allows the wearer to roll through the gait cycle without placing undue pressure on the heel and forefoot. The upper material consists of an outer wall of breathable, nylon mesh material lined with a soft, conforming material, reinforced at the heel by a heel cup that provides lateral stability. The heel cup is lined from the top by a full-length heel collar that conforms to the Achilles Triangle of the user, providing padding to the achilles tendon and under the malleoli, while at the same time making it impossible for the heel to slip out of the shoe during ambulation.
