A biplanar posting device having a board with a rear edge and a front edge and lines passing from the rear edge toward the front edge diverging toward the front edge and intersecting the front edge at an angle of about 70 degrees with a plate fixed to the upper surface of the board having end planar portions held in contact with the board and central diverging portions in the form of two flat planes diverging from the upper surface of the board at about 4 degrees and intersecting the planes in contact with the board at a line that overlays the diverging lines. An orthotic properly placed on the device and packed with plastic beneath the heel portion will inherently be formed with a lower surface to correct a defect in the bones of a patient.

Footwear and an insole pad employed inside thereof, in which an arch extrusion being raised toward the outside thereof is provided at an outer periphery corresponding to an outside arch on the upper surface of an insole of the footwear or on the upper surface of the insole pad, so that the shift of weight rested on a foot upon walking toward the outside upon walking is supported by the arch extrusion and the weight rested on the foot is gathered to the center of a body, which improves a walking posture, reduces the fatigue of the foot and prevents the occurrence of bowlegs.

A shoe or sandal is chosen which fits the patient's foot. One or more blanks of thermosoftening expanded plastics (e.g. an expanded cross-linked polyethylene) for constituting the insole are heated above the softening temperature and inserted in the shoe. The shoe is fitted on the patient's foot and the patient is walked until the insole is below the softening temperature. The insole may remain in the shoe or may be transferred to the patient's own footwear.

A supportive type of innersole device to automatically control proper placement of a molding mixture to receive and maintain the contours of a foot resting within any type of shoe. The first innersole element conforms generally to the shape of the sole and sides of the foot and shoe, extending back from the general area of the ball of the foot to the back of the heel, with centrally located opposing generally semi-circular cut out areas. A second innersole element of a generally dumbbell configuration is partially disposed beneath said first innersole element's semi-circular cut out areas, and is centrally connected to it to permit three dimentional conformity to the shape of shoe and foot in the absence of wrinkling. Disposed beneath these innersole elements is a flexible envelope containing novel means to prevent entry of the molding mixture into selected areas of the envelope, and to control the entry of the mixture into other areas of the envelope, said means consisting of a resilient cushion impermiably connected to selected areas of the top and bottom of the envelope, and a shaped semi-flexible plastic piece connected to the inside front edge of the envelope. The bag is provided with perforations thru which small amounts of the molding mixture pass to provide cementitious effect to unite all three elements with each other as well as anchoring the device to the shoe. A larger self sealing opening permits controlled entry of the molding mixture into the envelope.

A contour molded insole for footwear and method for producing the same to conform to an individual's foot includes at least one layer of material which is provided with plasticity for permitting shaping of the insole. An insole blank is shaped to include an upwardly concave surface portion which, under pressure, is caused to invert to form a convex surface. The insole is provided with a heelbone relief portion and layers of textile and cushioning material for completing a preferred embodiment.
