  • Patent number: 4490928
    Abstract: A mid-sole comprises a sole body of resilient foam material and a horseshoe-shaped rigid synthetic resin plate placed on the upper surface of the heel section of the sole body along the periphery thereof. At least one leg extends downwardly from the underside of the plate adjacent the inside portion of the heel section over its thickness to prevent the inner portion from inclining inwardly when a load is imposed on the inner portion of the heel section.
