  • Patent number: 4073024
    Abstract: An improved shoe is disclosed having a relatively flexible shank portion utilizing no shank reinforcement. The shoe comprises a substantially flexible insole attached to an upper. A wedge heel is attached to the insole at the heel seat thereof, and a wedge tunnel cover is attached to the front face of the heel and the bottom of the insole forward of the heel. The rear edge of an outsole covers the front edge of the wedge tunnel cover and stitching may be used to lock the insole, the outsole, the wedge heel and the wedge tunnel cover together so that they adequately support the weight of the wearer. The improved shoe is constructed by a novel method so that the forepart of the shoe is made by slip lasting while the remainder of the shoe is made using a cement construction.
