Abstract
Abstract A precast or molded insole for shoes adapted for use with several different heights of high heels comprising a main body, a first fiber board member formed to receive a preformed steel shank bonded to the bottom of the main body and a second fiber board member for nailing purposes bonded to the main body above said first fiber board member, said main body having a forepart shown as paddle-shaped, a shank depression in the first fiber board member extending longitudinally from in the heel area forwardly to about midway of the insole for the reception of a metal shank, and the like, after lasting, the heel portion rearwardly of the shank depression increasing in thickness. The insole is suitably contoured beneath for elimination of the use of a filler. A thin piece of paper product material is bonded to the forward two-thirds of the insole to assist in cementing the turned under portion of the upper or its lining and the outsole to the insole.
