Abstract

Overshoes are fitted onto selected ones of multiple shoes having different fashion configurations to protect the selected shoe against the elements. One overshoe includes an inner sheath of resiliently conformable material which engages the exterior of the selected shoe, with an outer shell having a requisite degree of resistance to the influx. An attachment arrangement couples the outer shell with the inner sheath in such a manner as to enable the resilient gripping configuration. Another overshoe includes a sheath of resiliently conformable material for engagement of the shoes such that upon engagement, the sheath will be secured to the shoe by conforming to a resiliently conformed configuration, and the fashion configuration of the selected shoe will be mimicked so as to be manifested for observation along the outer surface of the sheath. A protective construct is integrated for providing a requisite resistance to the influx of unwanted matter.

Description

' ADAPTABLE OVERSHOES

The present invention relates generally to overshoes and pertains, more specifically, to an overshoe capable of being fitted appropriately over any one of a plurality of shoes having different fashion configurations, without sacrificing the ability to provide protection against those elements associated with inclement weather.

Overshoes have long been in use as a practical and effective means by which ordinary shoes are protected against potentially damaging elements, such as water, mud, slush and other unwanted matter associated with inclement weather, such as rain and snow. However, the most effective protective materials usually employed in the construction of overshoes have not met with a great deal of acceptance for the construction of an overshoe to be used in connection with shoes having a wide variety of fashion configurations, primarily due to the inability of these protective materials to enable the construction of an overshoe to be properly fitted to any one of the wide variety of fashion configurations encountered in the world of fashionable footwear. In particular, the very wide range of fashions offered among women' s shoes has rendered it impractical for a woman to have available an overshoe capable of being fitted to every shoe in her wardrobe, or at least to some of her more fashionable shoes, coupled with the shoe for effective protection of the shoe, without impairing her ability to walk comfortably while wearing a fashionable shoe effectively protected by an overshoe. As a result, in many instances, a woman will remove her fashionable shoes in favor of wearing a more protective shoe or overshoe while walking in inclement weather, and will then change into her fashionable shoes upon reaching her destination. That procedure requires carrying or otherwise storing her fashionable shoes while wearing her more protective footwear, and vice-versa, with the concomitant inconvenience of contending with the bulk of additional footwear. Moreover, the highly limited range of aesthetic appearance heretofore available for overshoes, as a result of aesthetic limitations of shoe materials which can perform effectively in overshoes, has discouraged the use of overshoes for the protection of fashionable shoes.

The present invention provides an overshoe which overcomes the drawbacks outlined above. As such, the present invention attains several object and advantages, some of which are summarized as follows: Provides an overshoe construction which enables the use of highly effective protective materials in an overshoe capable of being fitted appropriately to a shoe having any one of a plurality of fashion configurations so as to enable coupling of the overshoe for effective use in connection with shoes of different fashion configurations; allows the use of a single pair of overshoes for selective fitting to any one pair of multiple pairs of shoes having different fashion designs, within a given size range, for effective protection of the selected pair of shoes against the influx of unwanted matter associated with inclement weather; assures an appropriate fit of an overshoe in connection with any one of a plurality of shoes of different exterior configurations; provides a relatively compact overshoe, readily stored and easily carried for convenient availability when needed to protect highly fashionable shoes having a variety of fashionable configurations; facilitates ease and effectiveness in fitting an overshoe appropriately to a fashionable shoe; allows the use of highly effective protective materials in an overshoe readily fitted and appropriately coupled to a shoe of stylish configuration; offers an aesthetically attractive overshoe without compromising a high degree of protection against conditions encountered in inclement weather; provides an overshoe which conforms so closely to any selected one of multiple shoes having different fashion configurations as to mimic and thereby manifest the fashion configuration of the selected shoe; simplifies and expedites the effective fitting of an overshoe to a shoe having a stylish fashion configuration; enables the construction of a relatively rugged overshoe to be used in connection with a variety of stylish footwear for effective protection and exemplary performance over a relatively long service life.

The above objects and advantages, as well as further objects and advantages, are attained by the present invention which may be described briefly as an overshoe for fitting onto a selected one of multiple shoes to protect the selected shoe against an influx of unwanted matter from outside the overshoe, each shoe being within a given size range and having an exterior with a fashion configuration different from fashion configurations of others of the multiple shoes within the given size range, the overshoe comprising: an inner retainer of resiliently conformable material, the inner retainer being dimensioned and configured for resilient conformance into a resilient gripping configuration capable of engagement with the exterior of any one of the shoes having respective exteriors of different fashion configurations within the size range, such that upon fitting of the inner retainer onto a selected shoe within the size range, the inner retainer will be secured to the selected shoe by conforming to the resilient gripping configuration when in engagement with the exterior of the selected shoe; an outer protector having a requisite resistance to the influx of unwanted matter through the outer protector, the outer protector being dimensioned and configured for essentially enveloping the inner retainer; and an attachment arrangement coupling the outer protector with the inner retainer along at least one prescribed location- between the inner retainer and the outer protector, with the inner retainer essentially enveloped within the outer protector, the one prescribed location being placed relative to the inner retainer and the outer protector for enabling the enveloped inner retainer to conform resiliently to the resilient gripping configuration in engagement with the exterior of the selected shoe, with the outer protector fitted over the selected shoe to protect the shoe against the influx of unwanted matter from outside the overshoe.

In addition, the present invention provides an overshoe for fitting onto a selected one shoe of multiple shoes to protect the selected shoe against an influx of unwanted matter from outside the overshoe, each shoe being within a given size range and having a toe, a heel and an exterior with a fashion configuration" different from fashion configurations of others of the multiple shoes within the given size range, the overshoe comprising: a sheath of resiliently conformable material, the sheath having an inner surface and an outer surface and being dimensioned and configured for resilient conformance into a resiliently conformed configuration capable of engagement with the exterior of any one of the shoes having respective exteriors of different fashion configurations within the size range, such that upon fitting of the sheath onto a selected shoe within the size range, the sheath will be secured to the selected shoe by conforming to the resiliently conformed configuration when in engagement with the exterior of the selected shoe, and the fashion configuration of the selected shoe will be mimicked so as to be manifested for observation along the outer surface of the sheath; a protective construct integrated with the sheath for providing the sheath with a requisite resistance to the influx of unwanted matter through the sheath; the sheath including a toe end, a longitudinally opposite heel end, a forward sheath portion adjacent the toe end, anankle sheath portion adjacent the heel end, and a heel opening adjacent the heel end; and a basal sole affixed to the forward sheath portion and extending longitudinally between the toe end and the heel opening.

The invention will be understood more fully, while still further objects and advantages will become apparent, in the following detailed description of preferred embodiments of the invention illustrated in the accompanying drawing, in which:

FIG. 23 is a rear elevational view of the overshoe of FIG. 22. Referring now to the drawing, and especially to FIG. 1 thereof, multiple women's shoes are illustrated in a group 20 of shoes shown in the form of a first shoe 22 having an exterior 24 with a fashion configuration 26 which includes a toe section 28 with a somewhat rounded configuration defining a particular style shoe 22, a second shoe 32 having an exterior 34 with a fashion configuration 36 which includes a toe section 38 with a somewhat pointed configuration defining another particular style shoe, and a third shoe 42 having an exterior 44 with a fashion configuration 46 which includes a toe section 48 with a somewhat squared-off configuration defining still another particular style shoe. Each shoe 22, 32 and 42 has a heel section 50 which includes a depending, moderately high heel 52, and an instep section 54 intermediate each respective toe section 28, 38, 48 and corresponding heel section 50. Shoes 22, 32 and 42 are merely illustrative examples of the wide variety of fashionable styles available to women. In this instance, all of the shoes 22, 32 and 42 are a part of a particular woman' s wardrobe of footwear and fall within a given size range of pairs of shoes appropriate to that woman.

Highly fashionable shoes, such as those illustrated in FIG. 1, present a woman with a dilemma when the woman contemplates wearing a pair of those shoes in inclement weather. Traditionally, an overshoe can be fitted onto a shoe to protect the shoe against the elements associated with inclement weather, such as water, mud, slush and other unwanted matter, the overshoe being constructed to protect the shoe against the influx of such unwanted matter. However, the exteriors 24, 34 and 44 having respective different fashion configurations 26, 36 and 46 exhibited by the multiple shoes 22, 32 and 42, would dictate the use of a selected one of multiple overshoes, each overshoe having a configuration complementing a corresponding fashion configuration, resulting in a wardrobe of overshoes for matching the wardrobe of shoes. Since most women would find it impractical to maintain a wardrobe of multiple overshoes, a woman may compromise by settling for an ill fitting overshoe, or she may decide merely to wear a relatively unfashionable, more weather-resistant shoe while traveling in inclement weather to her destination and then changing to a more fashionable shoe upon arrival at her destination, the more fashionable shoes having been carried by her, in some way, during her journey. The compromise overshoe, if constructed of a rugged, weather-resistant material, more often than not will be somewhat clumsy and unattractive, while a more attractive, somewhat better fitting overshoe can be less rugged and even rather flimsy. The use of an alternative, more weather-resistant shoe requires that the woman carry and store an extra pair of shoes for any one journey. The present invention provides another option, namely, a single overshoe construction which is conveniently fitted to any one shoe selected from the multiple shoes of different fashion configurations, without compromising an effective fit regardless of the fashion configuration of the selected shoe.

Turning now to FIGS. 2 and 3, an overshoe constructed in accordance with the present invention is shown at 60 and is seen to include an inner retainer in the form of an inner sheath 62 and an outer protector in the form of an outer shell 64. The inner sheath 62 has a slipper-like configuration and is constructed of a resiliently conformable material which is highly compliant, the inner sheath 62 being dimensioned and configured for resilient conformance into a resilient gripping configuration capable of engagement with the exterior of any one of the shoes 22, 32 or 42 having respective exteriors 24, 34 and 44 of corresponding different fashion configurations 26, 36 and 46, all within the given size range, such that upon fitting of the inner sheath 62 over a selected shoe 22, 32 or 42, the inner sheath 62 will be secured to the selected shoe 22, 32 or 42 by conforming to an appropriate resilient gripping configuration when in engagement with the exterior of the selected shoe, as will be described in further detail below. However, such highly conformable materials do not exhibit a high degree of resistance to permeation by the elements associated with inclement weather, so the inner sheath 62 alone, while being conformable into a highly effective resilient gripping configuration, will not provide the protection desired.

In order to provide overshoe 60 with the requisite degree of resistance to the unwanted matter associated with inclement weather, overshoe 60 includes outer shell 64 having a weather-resistant construction in a shoe-like configuration not necessarily dictated by the configuration of the exterior of- a shoe selected from the group 20 of shoes 22, 32 and 42. However, /outer shell 64 is dimensioned and configured for essentially enveloping inner sheath 62, as seen in FIG. 3. With the inner sheath 62 enveloped within outer shell 64, an attachment arrangement couples the outer shell 64 with the inner sheath 62 to establish fully assembled overshoe 60. The attachment arrangement is located between the inner sheath 62 and the outer shell 64 at a prescribed location placed relative to the inner sheath 62 and the outer shell 64 which enables the inner sheath 62 to expand and contract relative to the outer shell 64 so as to conform resiliently to the resilient gripping configuration in engagement with the selected shoe, while maintaining the outer shell 64 fitted to the selected shoe to protect the shoe against the influx of unwanted matter from outside the overshoe 60.

In the preferred embodiment illustrated in FIGS. 2 and 3, the outer shell 64 includes a toe end 70, a longitudinally opposite heel end 72, and an outer access aperture 74 between the toe end 70 and the heel end 72, the outer access aperture 74 having a perimeter 76. The inner sheath 62 includes a forward sheath portion 80, a longitudinally opposite rearward sheath portion 82, and an inner access aperture 84 between the forward sheath portion 80 and the rearward sheath portion 82, the inner access aperture 84 having a perimeter 86. The preferred construction includes an elastic band 87 integral with the inner sheath 62 around the perimeter 86 of the inner access aperture 84, for purposes set forth below. With the inner sheath 62 placed within the outer shell 64, the attachment arrangement includes an attachment element in the form of a seam 88 which couples together the inner sheath 62 and the outer shell 64 to establish the overshoe 60, the overshoe 60 including a forward end 90, a longitudinally opposite rearward end 92, a basal sole 94 extending along the bottom 95 of the overshoe 60, an altitudinally opposite upper top 96 and laterally opposite sides 98. The seam 88 is located at a strategic position 100, at a prescribed location placed intermediate the forward end 90 and the rearward end 92 of the overshoe 60. The prescribed location of the strategic position 100 is selected so as to enable the forward sheath portion 80 and the rearward sheath portion 82 to expand and contract resiliently into conformance with the resilient gripping configuration with minimal resistance, uninhibited by the outer shell 64, while assuring that the inner sheath 62 and the outer shell 64 are coupled to one another to establish an integrated assembly in the form of overshoe 60 which can be fitted readily to a selected shoe and which will provide a convenient, comfortable and effective overshoe 60.

The prescribed location of the strategic position 100 is along an instep section 110 of the overshoe 60, the seam 88 extending from the basal sole 94 to the upper top 96 and, preferably, along a rim 112 common with a forward segment 114 of each of the perimeters 76 and 86 of respective access apertures 74 and 84 to complete a secure attachment between the inner sheath 62 and the outer shell 64, and an attachment which will permit the requisite conformance of the inner sheath 62 to the exterior of a selected shoe, essentially uninhibited by the attachment of the inner sheath 62 to the outer shell 64, for exemplary performance of overshoe 60. In addition, since the instep section 110 of the overshoe 60 is least affected by forces on the overshoe 60 through flexing and bending -of the overshoe 60 during regular service, such as walking and the like, placing the seam 88 at the strategic location 100 assures that the attachment between the inner sheath 62 and the outer shell 64 will better withstand stresses imposed upon overshoe 60 during use. Other strategic locations are possible such as, for example, along the bottom 95 of the overshoe 60.

Referring now to FIGS. 4 through 6, as well as to FIGS. 2 and 3, outer shell 64 includes an opening 120 at the heel end 72 and a closure 122 for selectively opening and closing opening 120. In the illustrated embodiment, closure 122 includes a first flap 124 extending along one side 126 of the outer shell 64 from seam 88, and strategic position 100, rearwardly toward heel end 72, a second flap 134 extending along the other side 136 of the outer shell 64 from seam 88, and strategic position 100, rearwardly toward heel end 72, and complementary hook-and-loop fastener elements 140 and 142 at overlapping terminal end portions 144 and 146 of flaps 124 and 134. With the flaps 124 and 134 in an open configuration, as seen in FIGS. 3 and 4, access is enabled, through access apertures 74 and 84, for the insertion of a selected shoe, here seen as shoe 22. Access is provided to inner sheath 62 for the insertion of toe section 28 of shoe 22 through inner access aperture 84 and into forward sheath portion 80. The resilient, highly conformable nature of the material of inner sheath 62, together with the non-inhibiting location of the seam 88 at strategic position 100, enables the forward sheath portion 80 to accept readily and conform essentially to the configuration of the exterior of the toe section 28 of shoe 22 so as to grip the toe section 28 with a resilient gripping configuration essentially complementary to the toe section 28.

The rearward sheath portion 82 is pulled back, as seen in FIG. 4, to be fitted over the heel section 50 of shoe 22, as seen in FIG. 5, with the resilient, highly conformable nature of the material of inner sheath 62, together with the non-inhibiting location of the seam 88, enabling the rearward sheath portion 82 to expand readily and conform essentially to the configuration of the heel section 50 of shoe 22 so as to grip the heel section 50 with a resilient gripping configuration essentially complementary to the heel section 50, as seen in FIG. 5. At the same time, the depending heel 52 of shoe 22 is accommodated by extending through a heel opening 148 (see FIGS. 2 and 3) in inner sheath 62. Once the shoe 22 is fitted fully into the inner sheath 62, as seen in FIG. 5, the flaps 124 and 134 of the outer sheath 64 are moved to a closed configuration, as seen in FIG. 6, wherein the fastener elements 140 and 142 are engaged so that the flaps 124 and 134 are directed around heel opening 148 and envelop the inner sheath 62 between the strategic position 100 and the rearward end 92 of the overshoe 60. In addition, the elastic band 87, and the attachment along rim 112 at the forward segment 114 of each of the perimeters 76 and 86 of respective access apertures 74 and 84 establishes a relatively snug fit at the ankle of the person wearing shoe 22, providing added securement of the overshoe 60 to shoe 22, as well as added protection against the elements of inclement weather.

As seen in FIGS. 7 and 8, as well as in FIG. 6, with the overshoe 60 fitted onto shoe 22 (illustrated in phantom in FIGS. 7 and 8), the inner sheath 62 grips the shoe 22 with resilient gripping configuration 150 which is essentially complementary to the exterior 24 of shoe 22 by virtue of the resilient, highly conformable nature of the material of inner sheath 62. In this manner, inner sheath 62 readily is fitted onto any of the shoes 22, 32 or 42 and accommodates any of the different fashion configurations 26, 36 or 46, thereby enabling a single pair of overshoes 60 to serve any selected one pair of multiple shoes having exteriors with different fashion configurations, with the outer shell 64 providing exemplary protection against elements associated with adverse external conditions, such as inclement weather.

A suitable material for the construction of inner sheath 62 is a blend of ninety-five percent polyester and five percent Spandex. The inside of inner sheath 62 may include a fleece lining, as seen at 160, for protecting the exterior of the shoe placed therein, and a resilient layer 162 of polyurethane foam may be added to the outside of the inner sheath 62 for enhanced coupling of the inner sheath 62 with the outer shell 64. Outer shell 64 can be constructed of a conventional protective overshoe material, such as various rubberized materials or weather-resistant synthetic polymeric based materials. In addition, since outer shell 64 need not be configured precisely complementary to one particular fashion configuration, it becomes feasible to construct outer shell 64 of one of various textiles having a highly fashionable and aesthetically desirable visible appearance which can be displayed on the outer surface 170 of the outer shell 64, with the textile material treated so as to be resistant to the unwanted elements against which a shoe is to protected. Thus, outer shell 64 may be constructed of a textile material having a fashion display 172 on outer surface 170, the textile material being coated with one or both of a coating currently available from E.I. du Pont de Nemours and Company under the trademark DuPont Active Layer, for providing a protective layer, and a coating currently available from Schoeller Technologies AG under the trademark NanoSphere for providing added strength.

Another embodiment of the present invention is illustrated in FIGS. 9 and 10, wherein an overshoe 200 is in the form of a "bootie" style constructed to accommodate footwear in the form of low boots, one of which is illustrated in phantom at 210. An inner sheath 220 has an overall configuration generally complementary to low boots of various styles and, as described above in connection with inner sheath 62, is constructed of a resiliently conformable material capable of conforming to a resilient gripping configuration which will grip a selected low boot having one of multiple fashion configurations so as to secure overshoe 200 to the selected low boot. Protective outer shell 222 envelops inner sheath 220, and a seam 230 couples the inner sheath 220 with the outer shell 222 along strategic position 232. In a manner similar to that described above in connection with overshoe 60, an opening 240 in the outer shell 222 enables insertion of the low boot 210 into the inner sheath 220, and flaps 242 provide a closure, the closure including a slide fastener 244 at the terminal end portions 246 of the flaps 242. Once the flaps 242 are moved to the illustrated closed configuration to complete the envelopment of inner sheath 220 within outer shell 222, the slide fastener 244 is closed and the overshoe 200 is secured in place, fitted onto low boot 210.

Still another embodiment of the invention is illustrated in FIGS. 11 and 12, wherein an overshoe 300 is in the form of a "boot" style constructed to accommodate footwear in the form of high boots, one of which is illustrated in phantom at 310. An inner sheath 320 has an overall configuration generally complementary to high boots of various styles and, as described above in connection with inner sheath 62, is constructed of a resiliently conformable material capable of conforming to a resilient gripping configuration which will grip a selected high boot having one of multiple fashion configurations so as to secure overshoe 300 to the selected high boot. Protective outer shell 322 envelops inner sheath 320, and a seam 330 couples the inner sheath 320 with the outer shell 322 along strategic position 332. In a manner similar to that described above, an opening 340 enables insertion of the high boot 310 into the inner sheath 320, and flaps 342 provide a closure, the closure including a slide fastener 344 at the terminal end portions 346 of the flaps 342. Once the flaps 342 are moved to the illustrated closed configuration to complete the envelopment of inner sheath 320 within outer shell 322, the slide fastener 344 is closed and the overshoe 300 is secured in place, fitted onto high boot 310.

Referring now to FIGS. 13 through 17, another overshoe constructed in accordance with the present invention is shown in FIG. 13 at 400 and is seen to include a sheath 410 constructed of a resiliently conformable material, the sheath 410 having an inner surface 412 and an outer surface 414, and being dimensioned and configured for fitting over the exterior of any one of the shoes 22, 32 or 42, as depicted in FIG. 14 in connection with fitting overshoe 400 over selected shoe 22. Once fitted over shoe 22, as shown in FIGS. 15 through 17, the highly conformable material of sheath 410 enables resilient conformance of sheath 410 into a resiliently conformed configuration 420 wherein the inner surface 412 engages the exterior 24 of shoe 22 such that upon fitting of sheath 410 onto shoe 22, sheath 410 will be secured to shoe 22 by conforming to the resiliently conformed configuration 420, with the concomitant securement of overshoe 400 to shoe 22. At the same time, the highly conformable nature of the material of sheath 410 enables the conformance of sheath 410 to conformed configuration 420 to mimic the fashion configuration 26 of shoe 22 such that the fashion configuration 26 will be manifested along the outer surface 414 of sheath 410. As a result, the aesthetic appeal of the overall style and configuration of shoe 22 is preserved and rendered clearly observable, while, shoe 22 is protected by overshoe 400 against the influx of unwanted matter.

The material of sheath 410 is selected from available textile materials comprised of elastic fibers. In order to attain the requisite high degree of resistance to the influx of unwanted matter, a protective construct 430 is integrated with the sheath 410, the preferred protective construct 430 being in the form of a substantially waterproof protective coating 432 extending along the outer surface 414 of sheath 410. The inner surface 412 of sheath 410 preferably includes a soft lining integral with sheath 410, shown in the form of a synthetic fleece lining 434, for protecting the exterior 24 of shoe 22. A preferred material suitable for sheath 410, with integrated protective construct 430, is available from Eastex Products, Inc., of Holbrook, Massachusetts, under the designation Waverider. The Waverider material comprises a knitted elastic textile including polyester and Spandex, and a coating of polyurethane provides the material with requisite waterproof characteristics. The synthetic fleece lining 434 is laminated within the sheath 410, along the inner surface 412. In addition, the structure of the material enables the sheath 410 to "breathe", that is, to permit water vapor to pass through the material and out of the sheath 410 for preserving comfort while the selected shoe 22 is being worn with overshoe 400 in place. Further, the material enables "beading" of external water along outer surface 414 of the sheath 410, thereby facilitating rapid drying of the overshoe 400 and enabling convenient removal and storage of overshoe 400 after use. Sheath 410 includes a toe end 440, a longitudinally opposite heel end 442 and laterally opposite sides 444 extending longitudinally between the opposite ends 440 and 442. A forward sheath portion in the form of a toe box 450 extends along the sheath 410 adjacent toe end 440, and an ankle sheath portion 452 extends along the sheath 410, adjacent heel end 442. A heel opening 454 extends along the ankle sheath portion 452 between the heel end 442 and the toe box 450, the heel opening 454 having a heel perimetric edge 456. An ankle opening 460 extends between the heel end 442 and toe box 450, the ankle opening 460 having an ankle perimetric edge 462. A basal sole 470 is affixed to the toe box 450 and extends longitudinally between toe end 440 and heel opening 454. Sole 470 is constructed of a rugged, yet readily conformable material, and provides overshoe 400 with the requisite resistance to the influx of unwanted matter along the bottom of the overshoe 400, as well as a sure-footed tread 472, while enhancing the ability of overshoe 400 to remain in place over shoe 22, in the conformed configuration 420, during use. A preferred material for sole 470 is available under the designation Toughtek which comprises a polyester knit, stretchable fabric, coated with a heavily textured specially formulated Neoprene rubber.

In the preferred construction of overshoe 400, supplemental elastic surrounds are provided around heel opening 454, and around ankle opening 460. Thus, an elastic band 480 is integrated with sheath 400 along perimetric edge 456 of heel opening 454, and an elastic band 482 is integrated with sheath 400 along perimetric edge 462 of ankle opening 460. Upon fitting overshoe 400 over shoe 22, elastic bands 480 and 482 establish a relatively snug fit which provides added securement of the overshoe 400 to shoe 22, as well as seals for added protection against the elements of inclement weather. Turning now to FIGS. 18 and 19, a woman's shoe having yet another popular fashion configuration is illustrated in FIG. 18 at 500 and is seen to have an exterior 510 in the form of a wedge fashion configuration 512 which includes a toe section 514 and a heel section 516 having a depending, higher heel 518. In the wedge fashion configuration 512, the heel 518 extends forward toward the toe section 514 to include an intermediate heel portion 520 placed immediately below an instep section 522 of shoe 500.

As seen in FIG. 19, an overshoe 600 constructed in accordance with the present invention includes a sheath 610 of resiliently conformable material for being fitted over the exterior 510 of shoe 500, depicted in FIG. 19 in phantom, with the sheath 610 conforming resiliently to a conformed configuration 612 wherein shoe 500 is engaged by the sheath 610 to secure overshoe 600 fitted to shoe 500 with the overshoe 600 mimicking the fashion configuration 512 so as to manifest the fashion configuration 512 along the overshoe 600, while providing the requisite protection against the influx of unwanted matter. To that end, sheath 610 is constructed with a forward sheath portion in the form of a toe box 620 and a rearward sheath portion in the form of an ankle section 622. Ankle section 622 is elevated at heel end 624 of sheath 610 relative to toe box 620 to better follow the elevated heel 518 of shoe 500 and the rise along the instep section 522 of shoe 500. The ankle section 622 and the toe box 620 are joined together along a seam 630 which extends between the ankle section 622 and the toe box 620 in a generally altitudinal direction. In this manner, the two-part construction of sheath 610 more readily accommodates shoes having higher heels, as exemplified by shoe 500.

As in the earlier-described embodiments, sheath 610 is provided with a basal sole 640, an ankle opening 642 and a heel opening 644. In order to accommodate the extended intermediate heel portion 520 of shoe 500, basal sole 640 is somewhat shorter in longitudinal length than basal sole 470 of overshoe 400, thereby enabling heel opening 644 to be dilated sufficiently to better accommodate intermediate heel portion 520 while maintaining the integrity of the fit of sheath 610 along heel 518 of shoe 500.

Referring now to FIGS. 20 and 21, another embodiment of the present invention is shown in the form of overshoe 700 having an overall configuration in a "bootie" style constructed to accommodate footwear in the form of low boots, one of which is illustrated in phantom at 710. A sheath 720 has an overall configuration generally complementary to low boots of various styles and is constructed of a resiliently conformable material capable of conforming to a resiliently conformed configuration 722 wherein the sheath 720 engages the low boot 710 such that upon fitting the sheath 720 onto the low boot 710, sheath 720 will be secured in place on the low boot 710 by conforming to the conformed configuration 722, with the concomitant securement of overshoe 700 to low boot 710. At the same time, the highly conformable nature of the material of sheath 720 enables the conformance of sheath 720 to conformed configuration 722 to mimic the style and fashion configuration of low boot 710 such that the style and fashion configuration will be manifested for observation along the overshoe 700. As a result, the aesthetic appeal of the overall style and configuration of low boot 710 is preserved and rendered clearly observable, while low boot 710 is protected by overshoe 700 against the influx of unwanted matter. As before, overshoe 700 includes a basal sole 728.

In order to facilitate insertion of low boot 710 into overshoe 700, an access opening 730 is provided at heel end 732 of sheath 720, the access opening 730 being selectively opened and closed by a closure, shown in the form of a slide fastener 740 which extends altitudinally along the heel end 732. Upon opening access opening 730, overshoe 700 readily is fitted over low boot 710, with sheath 720 assuming the desired conformed configuration 722. Access opening 730 then is closed, completing the securement and conformance of overshoe 700 to low boot 710.

The construction of sheath 712 may be facilitated, while performance can be enhanced, by providing sheath 712 with a two-part structure. Thus, a longitudinally forward sheath portion in the form of a toe box 750 is joined to a longitudinally rearward sheath portion in the form of an ankle section 752, utilizing a seam 754 which extends generally altitudinally and along an intermediate instep section 756.

Turning now to FIGS. 22 and 23, still another embodiment of the present invention is shown in the form of overshoe 800 having an overall configuration in a boot style constructed to accommodate footwear in the form of high boots, one of which is illustrated in phantom at 810. A sheath 820 has an overall configuration generally complementary to high boots of various styles and is constructed of a resiliently conformable material capable of conforming to a resiliently conformed configuration 822 wherein the sheath 820 engages the high boot 810 such that upon fitting the sheath 820 onto the high boot 810, sheath 820 will be secured in place on the high boot 810 by conforming to the conformed configuration 822, with the concomitant securement of overshoe 800 to high boot 810. At the same time, the highly conformable nature of the material of sheath 820 enables the conformance of sheath 820 to conformed configuration 822 to mimic the style and fashion configuration of high boot 810 such that the style and fashion configuration will be manifested for observation along the overshoe 800. As a result, the aesthetic appeal of the overall style and configuration of high boot 810 is preserved and rendered clearly observable, while high boot 810 is protected by overshoe 800 against the influx of unwanted matter. As before, overshoe 800 includes a basal sole 828.

In order to facilitate insertion of high boot 810 into overshoe 800, an access opening 830 is provided at heel end 832 of sheath 820, the access opening 830 being selectively opened and closed by a closure, shown in the form of a slide fastener 840 which extends altitudinally along the heel end 832. Upon opening access opening 830, overshoe 800 readily is fitted over high boot 810, with sheath 820 assuming the desired conformed configuration 822. Access opening 830 then is closed, completing the securement and conformance of overshoe 800 to high boot 810.

The construction of sheath 812 may be facilitated, while performance can be enhanced, by providing sheath 812 with a two-part structure. Thus, a longitudinally forward sheath portion in the form of a toe box 850 is joined to a longitudinally rearward sheath portion in the form of an ankle and shin section 852, utilizing a seam 854 which extends generally altitudinally and along ankle and shin section 852, from an intermediate instep section 856.

It will be seen that the present invention attains all of the objects and advantages summarized above, namely: Provides an overshoe construction which enables the use of highly effective protective materials in an overshoe capable of being fitted appropriately to a shoe having any one of a plurality of fashion configurations so as to enable coupling of the overshoe for effective use in connection with shoes of different fashion configurations; allows the use of a single pair of overshoes for selective fitting to any one pair of multiple pairs of shoes having different fashion designs, within a given size range, for effective protection of the selected pair of shoes against the influx of unwanted matter associated with inclement weather; assures an appropriate fit of an overshoe in connection with any one of a plurality of shoes of different exterior configurations; provides a relatively compact overshoe, readily stored and easily carried for convenient availability when needed to protect highly fashionable shoes having a variety of fashionable configurations; facilitates ease and effectiveness in fitting an overshoe appropriately to a fashionable shoe; allows the use of highly effective protective materials in an overshoe readily fitted and appropriately coupled to a shoe of stylish configuration; offers an aesthetically attractive overshoe without compromising a high degree of protection against conditions encountered in inclement weather; provides an overshoe which conforms so closely to any selected one of multiple shoes having different fashion configurations as to mimic and thereby manifest the fashion configuration of the selected shoe; simplifies and expedites the effective fitting of an overshoe to a shoe having a stylish fashion configuration; enables the construction of a relatively rugged overshoe to be used in connection with a variety of stylish footwear for effective protection and exemplary performance over a relatively long service life.
