ABSTRACT:
The present invention teaches a novel, cushioned insole for footwear such as shoes, boots or the like. The insole comprises a multi-layered laminate that has a periphery which conforms generally to the shape of the inside surface of the sole of the footwear so that the insole may be readily placed in and removed from the footwear. The laminate preferably consists of a central, spongy core made of a foamed plastic material which is covered on its upper surface by a thin layer of generally fluid impervious plastic. The lower surface of the central core is covered with a thin layer of a fibrous material, such as paper. Three raised portions are provided which extend upwardly from the upper surface of the laminate. The first raised portion is located proximate the inner peripheral edge of the insole and extends generally longitudinally with respect thereto so as to provide support for the wearer's arch. The second raised portion is generally oval in shape with the major axis thereof extending longitudinally with respect to the insole and is placed such that it provides support for the wearer's metatarsis. The third raised portion extends generally transversely of the longitudinal axis of the insole and provides support for the wearer's phalanges. The laminate comprising the present invention is approximately 0.250 inches thick in the area thereof that is not raised, while the raised areas are not thicker than 0.375 inches. In the embodiment illustrated, the raised portion that supports the wearer's arch is the thickest while the raised portion that supports the wearer's phalanges is the thinnest of the three raised portions.
