  • Patent number: 4187621
    Abstract: A molded innersole for athletic and other shoes provides comfort and healthful distribution of weight on the foot through a construction which has laminated layers. A bottom layer of greater density and rigidity than a top layer (towards the foot of the wearer) with the construction of the top layer being softer and designed to take a partial compression set to produce a substantially permanent image of the wearer's toes, metatarsal arch and ball of the foot, at least. The upper soft layer is made of a closed cell foam and affords high impact absorption. The bottom layer is a firmer construction and performs the function when molded of retaining the general shape of the last used to make a specific shoe. Preferably both of these layers are made substantially of cross-linked polyethylene. Preferably a fabric moisture absorbing layer is provided above the said top layer, although other top layers may be used. The product is also highly resistant to tear and abrasion.
