Having fully described the invention, I claim:
l. A one-piece cushion insert for a shoe comprising a at cushion member of generally uniformtthickness having an outline conguration coinciding with the heel and shank portions of the insole of the Yshoe and seated thereon, said cushion member formed of resilient spongy material to support the same above the surface of the insole, said cushion member having a forward edge residing rearwardly of the metatarsal heads of the foot bones, whereby the cushion member yieldably supports the longitudinal arch of the foot, the underside of said cushion member having a recess beneath the oscalcis bone of the foot, said recess being generally oval in configuration having its major axis extending longitudinally of the cushion member, said recess delineating a yieldableweb normally spaced above the insole, said yieldable web having a thickness substantially one-half the full thickness of said cushion member, the portion of the cushion member marginally surrounding, said recess providing a load-bearing section yieldably supporting the peripheral heel portion of the foot which surrounds the oscalcis bone, said yieldable web being displaced downwardly under the downward pressure of the oscalcis bone.
2; A one-piece cushion insert for a shoe comprising a at `cushion member having an outline configuration coinciding with the heel and shank portions of the insole of the shoe and seated thereon, said cushion formed of resilient spongy material to support` the same above the surface of the insole, said cushion member having a forward edge residing rearwardly of the metatarsal heads of the foot bones, whereby the cushion member yieldably supports the longitudinal arch of the foot, the underside of said cushion member having a rst recess and having a second recess residing forwardly of said rst `recess adjacent the outer edge of the insole, said first recess residing beneath the oscalcis bone of the foot, said second recess residing beneath the cuboid bone ofthe foot, each of said recesses delineating a yieldable web integral with said cushion member, said yieldable webs each having a thickness substantially one-half the full thickness of said cushion member, the portion of the cushion member which marginally surrounds the said first recess providing a load-bearing section which yieldably supports the peripheral heel portion of the foot surrounding the oscalcis bone, the portion of the cushion member which is contiguous to said second recess providing a load-bearing section for supporting the ball portion of the foot adjacent the cuboid bone, the yieldable webs which are delineated by said first and second recesses yielding downwardly under the pressure of the foot.
