Also shown are optional seams 160 where two panels of liner material may be joined together to form the liner material into the general corresponding shape of a shoe upper. Pieces of liner material can be joined together by sewing, partial sewing, welding, gluing, etc. When pieces of liner are sewn together, the seams can be made
- the liner material 230 includes at least one layer of material which is waterproof and water vapor permeable (i.e., a functional material) , such as a breathable polymeric membrane, known as a waterproof functional layer 70.
- a functional material such as a breathable polymeric membrane, known as a waterproof functional layer 70.
- water vapor permeable and breathable are used interchangeably and mean that the functional layer has a water vapor coefficient Ret of less than 200 m 2 Pa W.sup "1 .
- Breathable polymeric membranes may be breathable by virtue of pores in the membrane or through a solution diffusion mechanism. Breathable polymeric
- the waterproof, water vapor permeable membrane is a membrane of microporous polytetrafluoroethylene .
- the microporous polytetrafluoroethylene membrane is a membrane of expanded polytetrafluoroethylene as taught in U.S. Pat. Nos . 3,953,566 and 4,187,390, to Gore.
- Such membranes of expanded polytetrafluoroethylene are commercially available from W. L. Gore and Associates, Inc., Elkton, Md., under the tradename GORE-TE . ® fabric. The subject matter of both of these U.S. patents is
- the liner material will contain at least the above described functional material 70 and at least one other material 60 laminated thereto.
- the liner can include the functional material and a textile material (desirably breathable) laminated or otherwise joined to at least one side, and often times joined to both sides thereof. Lamination is generally carried out with the use of a discontinuous pattern of suitable adhesive. Thus, water vapor permeability is not significantly effected.
- At least one other material can be a textile fabric. Textile fabrics can be woven, knit, mesh, nonwoven, felt
- Textiles can be produced from natural fibers such as cotton, or from synthetic fibers such as polyesters, polyamides, polypropylenes , polyolefins, or blends thereof.
- a textile fabric is laminated to the side of the functional material which will be in contact with the outer material of the upper 50.
- a textile fabric is laminated to the side of the functional material which will face the inside of the footwear.
- textile fabric is
- Suitable outer material of the upper includes leather, cordura, nylon, or the like.
- FIG. 7 shows a means for retaining the shape 80 of the upper assembly 10.
- This means is generally in the shape of the bottom of a foot and it is attached to the waterproof breathable functional layers by any suitable method known in the art, including, for example, stitching.
- the means for retaining the shape of the upper assembly can be any suitable material which is capable of being secured to waterproof breathable functional layers at the open bottom portion 150 and is compression resistant enough to maintain the shape of the upper assembly to form a bootie.
- the means for retaining the shape of the upper assembly can include, for example, a woven or nonwoven material, and for example, could be a strobel board, an elastic material, or a
- the textile may be formed from polyester, nylon, polyacrylic, polyolefin, polyurethane , polyvinyl, cotton, acetate, rayon, olefin, acrylic, wool, spandex, metallic, etc.
- the means for retaining the shape of the upper assembly can be secured to the bottom portion of the breathable layers by any suitable means.
- means for retaining the shape of the upper assembly can be secured to the bottom portion of the liner material 230 by stitching, partial stitching, stapling, welding, ultra sonic welding, etc.
- the means for retaining the shape 80 of the upper assembly 10 could include a string lasted liner. That is, it could be composed of strips of material holding together the upper assembly without need for additional material .
- a lasting process is carried out. Specifically, a shoe last, as known in the art, is inserted into the bootie at the open top portion
- a waterproof gasketing material is attached to the bottom surface portion of the bootie as part of a sole assembly.
- a means for facilitating the flow of polymer 100 throughout the sole assembly to adhere the sole assembly 20 and the lower portions of the upper assembly 40 together to form waterproof seal is placed at the bottom of the bootie for subsequent attachment.
- the means may be a spacer material, for example, a spacer mesh 110 cut into substantially the same shape as the bottom of the last.

- any other suitable means may be utilized as long as it is sufficiently compression resistant to retain flow channels during an injection process and sufficiently stiff and bending to facilitate lasting of the upper.
- the means may be a molded insole board 120 by itself.
- material/insole board composite may have one or more opening contained therein to facilitate the flow of
- the openings may be holes, channels, or the like.
- FIG. 7 there is shown a perspective view of the bootie 170.
- a spacer material/insole board composite is attached and is adhered to the bottom surface portion of the bootie.
- the spacer material is located on top of the insole board and directly in communication with the bottom of the bootie. In another embodiment the order is
- a molded insole board or spacer material by itself may be attached to the bottom portion of the bootie.
- the spacer material and insole board may be made of any suitable material with sufficient rigidity. Non-limiting examples include
- facilitating the flow of polymer 100 can be adhered to the bottom surface portion of the bootie using any suitable adhesive material.
- suitable adhesive materials include polyurethane and PVC, but any expandable and foamable substance sufficient for forming a seal may be utilized bootie.
- the adhesive must by flowable to an extent that flow through the
- the upper assembly 10 is pulled down, cemented (or otherwise attached to the bottom of the means for facilitating the flow of polymer 100) and folded over to fix the shape of the shoe upper to the last.
- the spacer material is positioned to keep the insole out of complete contact with bottom of the bootie so that the adhesive is able to completely seal the bottom of the bootie once injected into the openings.
- FIGs 1-3 are cross-sectional views of the footwear according to the invention wherein
- Outer sole 220 can be any suitable material such as, for example,
- polyurethane natural rubber, synthetic rubbers, leather, artificial leather, polyvinyl chloride, ethylene vinyl acetate, etc., and combinations thereof.

- an outersole may be cemented or otherwise attached (stitching, partial stitching, stapling, welding, etc) to the bottom of the footwear construction following injection or pouring of polymeric materials.
- waterproof footwear is determined as follows.
- the footwear is placed on top of a piece of blotter paper.
- the inside of the footwear is filled with room temperature water to a height of about 30 mm below the top line of the functional material (measured from the insole at the heel area of the footwear) .
- the water is allowed to stand in the footwear for at least two hours.
- the blotter paper and footwear upper are examined to determine if water has reached the blotter paper or the outside of the upper. If no water has reached the blotter paper or the outside of the upper, then the footwear is waterproof.
- the "waterproof, water vapor permeable functional layer” and the “waterproof gasket material” are “waterproof” if, when combined to form the footwear according to the invention, they result in the footwear being “waterproof” as defined above.
