Abstract
An insole insert for application into a shoe, and which is formed as a laminar material of various layers of paper, polymer, stranded thermoplastic or thermosetting material, foams of select consistencies and texture, in addition to a felt or microfiber type of upper layer, to add to the cushioning and softness of the insert, when applied. The insert, when subjected to heat and pressure, particularly pressure applied by the foot, conforms to the contours of the foot, and sustains such, even after prolonged usage after application into a shoe.
Claims5
An insert for a shoe including at least one layer of thermosetting polymeric material, said thermosetting polymeric material capable of being deformed and molded when subjected to the weight of the foot of the wearer, after said polymeric material is subjected to heat, said polymeric material thermosetting at least once when the temperature of said material is raised to a temperature greater than that of ambient temperature, said insert including a bottom layer having a shape conforming to that of the interior of a shoe, said one layer of thermosetting polymeric material being applied onto said bottom layer, said thermoplastic material layer comprising a strand of woven fabric of thermoplastic material which when subjected to heat and pressure of the foot undertakes the particular configuration and shape of the foot as the molding component applied thereto during application, a layer of material comprising a foam of polymer having impact resistance, applied to said one layer of thermosetting polymeric material, said layer of foam of polymer provided to add cushioning and shock absorbing to the insert and to provide resiliency and comfort to the shoe during usage and application.
