  • Patent number: 4322893
    Abstract: An independent insole assembly embodying an insole attachment member, or both insole and sole attachment members, each of which is integrally formed with depending pegs or clips for connection to spaced resilient means or springs that are interposed between the insole attachment member and a shoe sole, or between the two attachment members in the case where both insole and sole attachment members are used. The assembly is adapted to be incorporated in and connected to a shoe sole and upper during its manufacture and assembly of a shoe thereby to become an integral part of the shoe, with the resilient means or springs projecting upwardly from the shoe sole and resiliently supporting the independent insole assembly thereon. The insole attachment member has a foot-supporting portion and upstanding side portions which embrace the sides and heel of the wearer's foot to protect them from direct friction with the shoe upper during use.
