<p>Method and apparatus for manufacturing insoles with anatomically contoured shank portions, in which the shank portions are obtained by using the intended user's feet as matrix. After arranging on dual pans two thick strips (10) of a deformable spongeous-fibrous material and covering them with a liner made of an elastic cloth (13), a fluid polymer (12) is poured into said pans which reacts to set and foam in a conveniently short time. During the setting time, the user keeps his/her feet (14, 15) fixedly inside the pans, to thus leave an impression which accurately reproduces the shape thereof. After setting, the deformable strip is bonded to the liner and retains the exact impression left by the foot. Successive trimming operations provide an insole taylored to fit the user's feet. </p> |
