Definitions

  • the present invention relates to footwear, and more specifically to a removable insole adapted to be placed in any conventional type of shoe to provide greater comfort, aid in overcoming effects of excessive perspiration, make possible more effective control of foot infections, and to provide a more sanitary, more comfortable and generally more desirable insole than heretobefore lfnown or used.
  • the prime object of the present invention resides in the provision of a removable shoe insole comprising one or more layers of open weave, woven plastic fabric, the fabric being of the mono-filament type and of a plastic composition impervious to the effects of perspiration, so that although the individual strands of the fabric are entirely non-porous and non-absorbent, the open weave will permit unrestricted drainage and ample ventilation.
  • a further object of the invention resides in the provision of a removable shoe insole consisting of a plurality of layers of plastic fabric, the plastic being of a substantially non-hygroscopic composition, unaifected appreciably by temperatures in the range of 212 F. and of flexible mechanical characteristics, so that the insole may be cleansed and disinfected by boiling, without materially damaging the structure of the insole or altering the chemical composition of the plastic.
  • a further object of the invention resides in the provision of a removable insole of mono-filament plastic fabric adapted to retain reasonably its resilient characteristics and maintain an eiective air space between the foot of the wearer and the sole of the shoe to insulate the foot and provide greater comfort to the wearer under conditions of extremely high temperatures; as for example, combat conditions in tropical or desert cui l do not tend to accumulate.
  • an insole structure including one or more layers of open mesh fabric wherein the individual strands of the fabric are composed of a plastic composition that is insoluble and non-absorbent.
  • the present invention makes use of a mono-filament fabric; that is, a fabric wherein each individual strand is continuous, solid, resilient, non-porous, and non-absorbent, as distinguished from a thread made up of a multiplicity of relatively short hygroscopic strands of fibers.
  • the use of the mono-filament plastic fabric accomplishes certain unobvious and very desirable results in the reduction of foot infections and increase in foot comfort, for several reasons.
  • the individual strands of the fabric layers retain their springy resilient qualities even when the shoe is worn under conditions of extreme heat and humidity sumcient to cause excessive perspiration. Under such conditions, it is well known that any ordinary fabric becomes thoroughly soaked with moisture and matted into a soggy pad. having little or no cushioning effect, and entirely impervious to the circulation of air. In contrast, an insole manufactured according to the teachings of this disclosure'retains its full normal thickness and resiliency, since theindividual strands of the fabric absorb no moisture.
  • the mono-filament plastic fabric exhibits no tendency to flatten or mat, the interstices between the individual strands of the fabric are at all times open and unobstructed. This characteristic serves a dual function in that it provides full unobstructed drainage through the insole and since it permits a free and constant circulation of air throughout and between the individual insole layers, thus providing effective ventilation for the foot.
  • the characteristic of maintaining this air space within the insole provides a sufficient thermal insulating layer so that the shoe may be worn under excessively high temperature conditions without great discomfort.
  • Figure 1 is a plan view of an insole constructed in accordance with the teachings of this disclo-l sure.
  • Figure 2 is an enlarged detail sectional view taken substantially on the plane of the line 2-2 of Figure 1.
  • Figure 3 is an enlarged detail sectional view similar to Figure 3 and illustrating a modified form of edge binding for the insole.
  • the insole generally indicated at I0, consists of a plurality of layers of fabric II, I2, I3, Il, and I5, formed to correspond with the shape of the inside of a shoe and bound together around their marginal edges. As illustrated in I and ⁇ i! of the drawings, the individual layers of fabric are united by a binding strip I8 stitched to the fabric layers by a line of stitches Il.
  • binding strip I6 may be of plastic, composition, rubber, fabric, leather, or any other flexible material having satisfactory wearing qualities.
  • the invention is not regarded as limited to a stitched edge binding and it is contemplated that the several layers of plastic fabric may be brought together at the edges and sealed by fusing the individual layers of the plastic together at the extreme edge, to form a fused binding I8 as illustrated in Figure 3, or by cementlng.
  • the novelty of the present invention resides particularly in the provision of a removable insole wherein the individual layers of fabric are composed of an insoluble and non-absorbent open mesh plastic fabric of the mono-filament type, having each individual thread of the fabric lformed of 'an extruded, solid, non-porous, and
  • non-absorbent' filament of plastic material is non-absorbent' filament of plastic material.
  • beneilcial results may be obtained by inserting a medicated fabric layer between the layers of fabric heretofore described, so that the medicament will be gradually dissolved or disseminated by means of heat and perspiration incident to use asthe insole is worn,'to provide a constant antiseptic tending to maintain the insole in a completely sterile condition at all times.
  • Paraformaldehyde, trioxymethylene and menthol, with or without the addition of boric acid are possible medicaments, though vother suitable substances may be employed.
  • a ⁇ medicated pad as thus de'- scribed may be of any size and shape, though it is contemplated that it will probably be most satisi'a'ctory in the general conguration indicated at I9 in the drawings, spaced and located to provide medicament in the vicinity of the toes of the shoe.
  • a shoe insole comprising a plurality of layers of open weave plastic fabric superimposed upon one another; each of the fabric layers consisting of a multiplicity of solid, resilient, nonporous, non-hygroscopic, extruded strands of temperature resistant, flexible plastic; the strands being woven together into an open mesh fabric having the interstices between the individual strands Wider than the diameter of the individual strands: all of the fabric layers being cut to a size and shape approximately the size and shape of a human foot and all of the layers being fused ether around their marginal edges.
  • An inner sole for a shoe or the like compris# ing a plurality of woven webs of thermoplastic threads having a welded joint about its periphery, the said inner sole when free of load being convex in cross-section and having a. ⁇ greater thickness within the welded vperipheral joint than at the welded peripheral Joint.
  • a .plastic inner sole comprising a plurality of superimposed layers of inner sole shapes fused together along the edges, said layers comprising relatively coarse intermediate layers and a ne outer layer.
  • a plastic inner sole comprising a. plurality of es superimposed woven layers of inner sole shapes fused together along the edges. said layers comprising relatively coarse intermediate layers and a iine outer layer. and a medicated pad positioned between two of said woven layers.
