First Claim
1. An innersole for underlying a human foot, said human foot having a forefoot, a rearfoot, a centroid region, a calcaneal region, and a metatarsal arch, said innersole comprising:
- a) a first layer having a first hardness and a shape corresponding to the full plantar sole of the human foot, and a lowermost portion of the first layer lying in a first planeb) a second layer having a second hardness, said second layer for underlying the periphery of the forefoot, the periphery of the rearfoot, and the centroid region of the foot and said second layer having means defining a first opening for underlying the calcaneal region and means defining a second opening for underlying the metatarsal arch, and a uppermost portion of the second layer lying in a second planewherein the second hardness is greater than the first hardness and, the second layer is positioned beneath and is distinct from the first layer and the first and second planes being directly adjacent.

Abstract
An innersole for use in a shoe or the like and generally having a shoe-shape said innersole comprising a first region having a first hardness, said first region designed to underlie the periphery of the rearfoot, the centroid region of the foot and the periphery of the forefoot, and, a second region having a second hardness, said second region designed to underlie the calcaneal region and the metatarsal or transverse arch, wherein the first region is about 5 to about 15 Shore A durometer harder than the second region. The first region is preferably a second layer and the second region is preferably a first layer. The first layer is generally shoe-shaped and has a first hardness. The second layer has a second hardness and is designed to underlie the periphery of the forefoot, the periphery of the rearfoot, and the centroid region of the foot and said second layer having means defining a first opening designed to underlie the calcaneal region and means defining a second opening designed to underlie the metatarsal or transverse arch. The second hardness is greater than the first hardness and the second layer is positioned beneath the first layer or is embedded therein so as to be substantially integral a lower surface of the first layer. A shoe and method employing the insole are also encompassed by the invention.
