Abstract: Method of making insole of non-woven bonded fiber sheet material including a shank portion of greater stiffness and density than the forward portion in which a through layer of non-woven fiber sheet including a heat-softenable binder is associated with one or more layers of non-woven fiber sheet including binder in the heel and shank or waist portion of the insole and the layers in the heel and shank or waist portion are consolidated by heat and pressure to a unitary board-like state in the heel and shank region. The insole including the heel and shank region may be given a contour approximating the contour of a bottom of a foot in a pressing operation and may also incorporate a layer of stiff plastic sheet material.
