Insole for a shoe

Abstract

The present invention relates to an insole installed inside a shoe to contact each foot sole portion of the human forefoot (A), midfoot (C) and rearfoot (B), which is made of a plurality of materials having varying degrees of hardness depending on the insole region, wherein the respective materials are combined to form a single layer. Preferably, the insole for a shoe comprises: a base plate with any one of a forefoot hole, a midfoot hole and a rearfoot hole formed therein corresponding to one of respective foot regions (A), (B) and (C); and an inner plate including one or more of a forefoot support, midfoot support and rearfoot support to be inserted into one of the holes, and, respectively, wherein the base plate and the inner plate are manufactured with materials having varying degrees of hardness relative to one another.
