Definitions

  • the present invention relates to an item of footwear which is impermeable to liquid water (i.e. is waterproof) but is water-vapour-permeable so as to be comfortable to wear.
  • the invention is particularly applicable to sports shoes, boots, slippers or socks.
  • Waterproof water-vapour-permeable materials are available from W.L. Gore & Associates under the trademark GORE-TEX. These comprise a thin membrane of porous polytetrafluoroethylene (PTFE) which may be produced in the manner described in US patent 3953566. Usually, the porous expanded PTFE membrane is coated with an oleophobic coating, as disclosed in US patent 4194041, in order to prevent the membrane from being wetted-out by fats or oils from the wearer's body.
  • PTFE polytetrafluoroethylene
  • oleophobic coating as disclosed in US patent 4194041
  • other waterproof water-vapour-permeable membranes are also available on the market and the invention is applicable to these also.
  • the bootee In order that the shoe shall be fully water tight, it has been conventional practice to initially produce a bootee of a relatively soft waterproof water-vapour-permeable material around which the shoe is constructed.
  • the bootee includes an opening for the foot and is usually formed from two side portions and a sole portion. The joins are generally butt-edged, secured withzig-zag stitching and sealed. The bootee can then be pretested for leaks before being put into the final shoe.
  • the bootee is formed of a conformable four layer laminate comprising from the outs . ide inwards, a layer of nylon knit, .a membrane with oleophobic coating, a foam layer and an inner fabric lining to go adjacent the foot.
  • the flexible nature of the bootee can cause difficulty in subsequently aligning the bootee on a last in order to allow the upper and outer sole to be attached.
  • the present invention provides an item of footwear which is impermeable to liquid water but is water-vapour-permeable which comprises;
  • the upper portion being formed of a laminate comprising an inner lining material and an outer water-impermeable water-vapour-permeable layer; and the midsole being formed of an inner midsole board laminated to an outer water-impermeable water-vapour-permeable layer;
  • the upper portion having an entrance for a foot and a lower lasting margin, the lasting margin being lasted around the periphery of the midsole so as to overlap the midsole periphery and being attached thereto so as to form a seam;
  • the invention also extends to a process of production wherein the inner lining is. formed on a last. The last is then withdrawn and the seam seal tape applied. The sealed inner lining is then returned to the last and an outer sole and upper applied. The outer uppers will be on the outside of the finished shoe. Alternatively the seam sealing tape may be applied while the inner lining is still on the last.
  • the inner lining is formed of laminated materials.
  • the inner lining material of the upper portion is preferably a material having limited stretchability, such as leather, such that it requires to be formed on a last.
  • the laminate is preferably formed by adhering the water-impermeable, water-vapour-permeable layer with adhesive under the application of pressure to the outside of the inner lining layer.
  • the midsole is preferably formed by adhering the water-impermeable. water-vapour-permeable layer to the outside of a semi-rigid midsole board material.
  • the water-impermeable, water-vapour permeable layer (such as expanded porous PTFE and oleophobic coating) is preferably protected on its outermost side with a loose knit fabric layer, which nevertheless allows penetration of adhesive used with the seam seal tape through to the water-impermeable, water-vapour-permeable layer for sealing purposes.
  • the upper portion of the lining " is generally made in conventional manner from panels which are butt jointed and stitched;and the seams sealed with seam seal tape.
  • the upper usually of leather
  • the upper may ' be attached to the inner lining around the ankle area but is otherwise left loose to be lasted in later.
  • an upper may not be required.
  • the water-impermeable water-vapour-permeable layer of the lasting margin may be sealed to the water-impermeable water-vapour-permeable layer of the midsole by means of a suitable adhesive (which will form a waterproof seal, which may or may not be water-vapour-permeable) or a gasketting material such as expanded porous PTFE tape impregnated with an adhesive placed between the lasting margin and the midsole.
  • a suitable adhesive which will form a waterproof seal, which may or may not be water-vapour-permeable

  • it is preferred to seal the seam by adhering seam seal tape over the seam in known manner.
  • The.seam seal tape may be any suitable tape provided with an adhesive on its inner surface. It is often of the same material as the water-impermeable water-vapour-permeable layer. It is preferably formed of a water-impermeable water-vapour-permeable expanded porous PTFE membrane having an oleophobic coating thereon. Usually, a thermoplastic adhesive is attached to one side of the tape, whilst a protective fabric layer is applied to the other side. The seam seal tape may be applied by heating such as to melt the adhesive and applying under pressure.

  • the tacks 14 are withdrawn and the holes left are sealed with patches 28 of seam sealing tape.
  • the last is withdrawn by hinging the heel portion of the last in conventional manner.
  • This allows seam sealing tape 24 to be applied over the seam 26 between the upper portion of the lining and the midsole.
  • the expanded porous PTFE layer lies on the outer side of the leather lining 10.
  • the seam seal tape 24 is applied under heat and pressure such that the hot melt adhesive " penetrates the nylon fabric 11 and securely adheres to the porous expanded PTFE membrane on either side of the seam 26, thereby sealing the seam against ingress of liquid water.
  • the sealed lining is then replaced over the last.
  • the leather upper 6 (which was previously lifted upwards out of the way) is now pulled downwards over the last and in a second lasting process is conformed to the shape of the last and extends beyond the lower edge thereof so as to provide an overlap portion 19.
  • a layer of hot melt adhesive 21 is then applied around the periphery of the midsole and over the seam sealing tape 24.
  • the peripheral portion 19 (which may be skived to reduce its thickness) is then lasted around the lower edge of the inner liningand adhered thereto. Any folds or puckers formed in the overlap area 19 can be ground away in conventional manner.
