  • Patent number: 4331152
    Abstract: An orthopedic shoe in which the tip is automatically erected when the wearer's foot is raised to bring it forward to take a step during walking. A flexible metal plate is concealed or sandwiched at one end between two portions of a sole with one portion forming an inner sole and the other portion an outer sole covering the metal plate. The one end of the metal plate is fixed between the soles. The metal plate is connected with a thrust member which includes a thrust bar, and a compression spring which are activated by the position and weight of the foot either to raise the tip of the shoe above the ground or to raise the heel portion above the ground. The thrust action of the spring onto the metal plate causes the toe portion to be elevated, and the force of the thrust bar onto the compression spring causes the heel to be elevated in response to pressure exerted onto the thrust bar by the metal plate. The thrust member is concealed in the heel.
