Title: Elastic Woven Shoe

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     This invention relates generally to footwear, and in particular to an elastic woven footwear. 
     Description of the Related Art 
     Woven shoes (or weave shoes) are well known in the shoe industry. These woven shoes may also be referred to as basketweave shoes, since the weave consists of warp (conventionally known as lengthwise) strands and weft strands. Warp and weft strands are interlaced so that they form a simple crisscross pattern. For the purposes of forming a basketweave for a shoe, the concepts of length strands and width strands are not relevant, and the terms warp strand and weft strand may be used for the purpose of distinguishing between the two intersecting directions of the strands. 
     Woven shoes generally provide the advantages of being comfortable and lightweight. With the proper weave material, the woven uppers of a shoe can expand to keep swollen feet comfortable. Using a stretchy, elastic type material for the woven upper of a shoe allows for the shoe to expand. This enhances comfort for the wearer. 
     Woven shoes also have an appearance that many consumers desire. The weave can be configured in a variety of patterns, and with a variety of materials. Woven shoes are often used for casual footwear, but can also be elaborate enough to accommodate the dress look. To further vary their appearance and styles, woven shoes can have a variety of heels and soles. 
     A popular style of woven shoes are flats for women. Woven flats blend casual style with comfort. Many woven flats have the entire upper of the shoe comprised of a woven upper. To increase comfort, the woven upper is made of an elastic material. A disadvantage of having the entire upper made of an elastic woven material is that the shoe may not have enough structure and rigidity to securely stay on the foot. This can especially be a problem during rigorous foot motion. This can also become an issue over time, when the elastic material loses its elasticity and becomes stretched. 
     There is a need for an elastic woven shoe to provide improved structure, form, and rigidity to enhance how the shoe secures to the foot. There is also a need to improve the longevity of the shoe, as the elastic material may lose its elasticity over time. 
     BRIEF SUMMARY OF THE INVENTION 
     A woven shoe with an elastic weave portion, attached to a non-elastic section is described herein. A weave that is elastic provides increased comfort for the wearer, especially if the elastic weave portions are positioned at common stress points. Also, elasticity naturally helps to fit better to the variety of foot shapes and sizes. An elastic weave portion will have the natural disadvantage of not having as much form, structure, or rigidity. The elastic weave portion is complemented with a non-elastic reinforcement section to improve it&#39;s form, structure, and rigidity. 
     The elastic weave portion has a basketweave pattern, and as is conventional with a basketweave, is comprised of warp strands and weft strands interlaced to form a crisscrossed pattern. The elastic weave portion is attached to the reinforcement section by interlacing and wrapping through a slit in the reinforcement section. This attachment provides a superior hold for the purposes of improving the elastic weave portion&#39;s form, structure, and rigidity.

     DETAILED DESCRIPTION 
       FIG. 1  shows a first embodiment of an elastic woven shoe  100 . The elastic woven shoe  100  has an elastic weave heel counter portion  120  and an elastic weave vamp portion  110 . This elastic woven shoe also has other conventional shoe parts, such as a midsole  150 , outsole  160 , and quarter  170 . The elastic weave portion is conventionally weaved through punch holes of the midsole, and is secured through a heat press of adhering the outsole and the midsole together with glue. 
     Each elastic weave portion is attached to a corresponding reinforcement section. A reinforcement section is not elastic, and serves to provide more stability and form to the elastic weave portions. The reinforcement section complements the elastic weave portion to improve the longevity and performance of the shoe. The reinforcement section may be comprised of a variety of non-elastic material, such as leather or PU (polyurethane). The reinforcement section may also be comprised of fabric in various shapes. In this embodiment, the elastic weave heel counter portion  120  is attached to the heel counter reinforcement section  130 , and the elastic weave vamp portion is attached to the vamp reinforcement section  140 . The elastic weave vamp portion  110  is attached to the vamp reinforcement section  140 . 
     The heel counter reinforcement section  130  is a strip that has both ends anchored at the sole of the shoe. The vamp reinforcement section  140  is a strip that also has both ends anchored at the sole of the shoe. Both the strips  120   140  have their two ends on opposing sides of the shoe from one another. These reinforcement sections may be anchored at the sole of the shoe with or without glue. When anchored to the sole of the shoe without glue, they may be secured by stitching to the midsole. 
     The elastic weave portions are attached to the reinforcement sections without the need for adhesive or conventional stitching. Rather, the elastic weave is attached to the reinforcement section by extending the interlacing nature of the weave strands through the reinforcement section. This attachment is far superior and elegant over the conventional methods of adhesive or stitching. The use of adhesive or conventional stitching may be employed to complement the interlacing attachment. 
       FIG. 2  shows in more detail how the elastic weave heel counter portion  120  is attached to the heel counter reinforcement section  130 . The heel counter reinforcement section  130  has a number of slits for attaching to the elastic weave heel counter portion  120 . For example, one example slit  210  has weave strand  220  going through it. Weave strand  220  goes into the slit  210 , and bends, to wrap around behind the heel counter reinforcement section  130  and continues as weave strand  230 . The weave strand  220  starts as a first warp, and after looping through the slit  210 , continues on as a second warp. 
     This style of attachment interlaces the weave with the reinforcement section, and provides a very strong, and consistent attachment for the elastic weave portion with the reinforcement section. The warp weave strand itself is able to be one continuous strand through the slit, allowing for the natural strength of the strand to form the attachment. Also, when the elastic weave pulls against the reinforcement section, through natural foot motion, this design allows the entire elastic weave portion to be better secured, since all the attached warp strands collectively be secured through this attachment. 
       FIG. 3  shows a second embodiment of an elastic woven shoe  300 . The elastic weave portion  310  in this embodiment comprises of a majority of the shoe&#39;s upper portion. The elastic weave portion  310  attaches to the shoe&#39;s facing  320 . (The facing is the part of the shoe where the shoelace eyelets are located.) The facing  320  serves as the reinforcement section, and is comprised of a non-elastic material, such as leather, PU or fabric. The elastic weave portion  310  attaches to the facing  320  through interlacing, but in a different style as the first embodiment. In this embodiment, the facing is not anchored to the bottom of the shoe by stitching, as the facing offers the desired tightness with the adjustable shoe laces. 
       FIG. 4  shows the elastic woven shoe  300  from a top perspective view, to better demonstrate the attachment of the elastic weave portion  310  with the facing  320 .  FIG. 4  shows the exterior of the shoe on the left side, and the interior of the shoe on the right side. There is a flap  330  under the facing  320  that is pulled back to better see the elastic weave portion  310  adjoining the facing  320 . The flap  330  or liner is placed for added comfort to the wearer. In  FIG. 4 , there is a warp  340  that goes into a slit on the facing. The warp  340  enters the slit and bends back, wrapping down behind the facing, and continues as weft  350 . As such, there is a continuous weave strand that acts as both a warp  340  and weft  350 . The positioning of the slits relative to the weave direction makes it possible to have a continuous weave strand interlace through the slit and switch from a warp  340  to a weft  350 . 
     The attachment between the elastic weave portion  310  and reinforcement section  320  is arguably stronger than the first embodiment. As before, this style of attachment does not require adhesive or conventional stitching, and provides a superior hold. Further, when the elastic weave portion  310  is stressed from natural foot motion, the entire elastic weave portion  310  is better secured by the reinforcement section  320  since the many attached warps and wefts are directly held through interlacing with the reinforcement section  320 . 
     Although the present invention has been described in detail with respect to certain embodiments and examples, variations and modifications exist which are within the scope of the present invention as defined in the following claims.
