Abstract:
An insole is provided for reducing peak plantar pressure on a foot. The insole includes a compressible pad having a plurality of holes extending from a bottom surface of the compressible pad and partially through the compressible pad. A plurality of compressible plugs is disposed in the plurality of holes, wherein the plurality of compressible plugs has a stiffness that is different than a stiffness of the compressible pad. The plurality of compressible plugs is concentrated in a reduced stiffness portion of the compressible pad that substantially corresponds to an area of peak plantar pressure on the foot.
