The principles and operation of an overshoe according to the present invention may be better understood with reference to the drawings and accompanying descriptions.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

Referring now to FIGS. 1A and 1B, there is depicted an embodiment 10 of an overshoe in accordance with the principles of the present invention, positioned on a shoe 12. Overshoe 10 comprises a lower section 14, which is placed beneath the sole 16 of shoe 12, and an upper section 18 which is configured to fit over at least a portion of the outside of shoe 12.

Lower section 14 is formed from a flexible, semi-rigid material, and is provided with at least one anti-slip feature 20, which increases traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. Anti-slip feature 20 may comprise, for example, a protrusion such as a rubber spike, a stud, a raised feature studs 20a or raised bars 20b, or the like. In overshoe 10 anti-slip features 20 are spaced apart in a pattern, whereby each anti-slip feature 20 is adjacent to a space of at least the dimensions of the anti-slip feature, such that when overshoe 10 is rolled up, each anti-slip feature is positioned within one such space, enabling overshoe 10 to be stored in a compact form.

According to some embodiments of the present invention (e.g., overshoe 10 depicted in FIGS. 1A and 1B), lower section 14 of overshoe 10 comprises at least one strip 22 having a length equal to at least a portion of the length of sole 16 of shoe 12, and a width equal to at least a portion of the width of sole 16 of shoe 12. Further according to some embodiments of the present invention, lower section 14 of overshoe 10 optionally comprises a lower heel section 24, integrally formed with strip 22, which is positioned beneath at least a portion of heel 26 of shoe 12.

As seen in FIGS. 1A and 1B, the two ends of lower section 14 of overshoe 10 are connected to opposite ends of upper section 18 of overshoe 10.

According to some embodiments of the present invention (e.g., overshoe 10 depicted in FIGS. 1A and 1B), upper section 18 of overshoe 10 includes a back section 28, which extends upwards from lower heel section 24 of overshoe 10, around at least a portion of back 30 of shoe 12. Further according to some embodiments of the present invention (e.g., overshoe 10 depicted in FIGS. 1A and 1B), upper section 18 of overshoe 10 comprises a toe section 32, which extends upwards from lower portion 14 of overshoe 10, over at least a portion of toe section 34 of shoe 12, and extends into vamp portion 36, covering at least a portion of vamp 38 of shoe 12. In some such embodiments, toe section 32 and back section 28 of overshoe 10 are connected by an instep section 40, positioned across the instep 42 of shoe 12.

According to some embodiments of the present invention (e.g., overshoe 10 depicted in FIGS. 1A and 1B), instep section 40 of overshoe 10 may optionally comprise a releasable fastening feature 44, which may be opened and closed in order to enable overshoe 10 to be easily positioned on, or removed from, shoe 12. Fastening feature 44 may comprise any such feature known in the art, such as a hook and loop fastener, a clip, a clasp, a buckle, a zipper, a press-stud, a button, a hook and eye, a lace, a tie fastener, or the like. Fastening feature 44 may be adjustable, such that instep section 40 may effectively be shortened or lengthened, according to the size of the wearer's footwear, thereby enabling a single overshoe 10 to be adapted for use with a wide range of footwear sizes. Also optionally, an adjustable feature may be provided on vamp portion 36 (not shown), adjusting the length of vamp portion 36, thus further increasing the adaptability of overshoe 10 for use with a wide range of footwear sizes.

Lower section 14 and upper section 18 may be integrally formed. Alternatively, upper section 18 may be connected to lower section 14 by a plurality of detachable fasteners (not shown). Optionally, upper section 18 may be provided as an integrally-formed unit comprising toe section 32, vamp portion 36, back section 28, and instep section 40. Alternatively, all or some of toe section 32, vamp portion 36, back section 28, and instep section 40, may be provided as separate, detachable, straps which may be reversibly connected to form upper section 18 of overshoe 10.

Although overshoe 10 is illustrated for use on a sneaker, it should be appreciated that the design may easily be adapted for use with any item of footwear, including any type of shoe, boot, or sandal, having any height of heel. For example, the overshoe is suitable for use over a high-heeled shoe, preferably by addition of at least one further lower strip (not shown), in addition to lower heel section 24, wherein the additional strip is positioned beneath the arch of the footwear, such that lower portion 14 follows the contours of sole 16 of shoe 12. In embodiments of the invention, especially configured for use with high heel shoes, the toe section is provided with an opening through which the point of the toe of a shoe can protrude. When used, the toe of a shoe protrudes through the opening through the toe portion of the overshoe, encircling the toe of the shoe and thus holding the overshoe of the invention tightly associated with the shoe. Such an embodiment is especially suitable for use with shoes having relatively pointy toes.

FIGS. 2A and 2B depict an alternative embodiment 50 of an overshoe in accordance with the principles of the present invention. Embodiment 50 differs from embodiment 10 in a number of aspects including that lower section 14 comprises, in addition to lower heel section 24, at least one further lower strip 52 for placement beneath sole 16 of shoe 12, and extending essentially perpendicular to strip 22. As shown in FIG. 2A, overshoe 50 may optionally comprise, for example, three such additional lower strips 52, wherein a first lower strip 52a is positioned beneath a front end 54 of sole 16 of shoe 12; a second such lower strip 52b is positioned beneath the widest portion of sole 16 of shoe 12; and a third such lower strip 52c is positioned proximal to the narrowest portion of sole 16 of shoe 12. Alternatively, lower section 14 of overshoe 50 may optionally comprise, one, two, four, or more such lower strips 52, positioned beneath sole 16 of shoe 12. Each lower strip 52 is preferably connected to vamp section 36 of overshoe 50 by an upper strip 54. As depicted in FIGS. 2A and 2B, overshoe 50 is formed from an elastic material (e.g., silicon rubber) which is stretched by pulling to position overshoe 50 on shoe 12. Alternatively, overshoe 50 may include a fastening feature 44 (not shown) as described above with regard to overshoe 10, provided on instep section 40.

As with overshoe 10 depicted in FIGS. 1A and 1B, lower section 14 of overshoe 50 is provided with at least one anti-slip feature 20, which increases traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. Anti-slip features 20 of overshoe 50 consist of a plurality of studs 20a. In overshoe 50 anti-slip features 20 are distributed in such a way as to provide good traction but also to not interfere with folding or rolling of overshoe 50, enabling overshoe 50 to be stored in a compact form.

FIGS. 3A and 3B depict an alternative embodiment 80 of an overshoe in accordance with the principles of the present invention. As with other embodiments of the invention, overshoe 80 comprises a lower section 14, which is placed beneath the sole 16 of shoe 12, and an upper section 18 which is configured to fit over at least a portion of the outside of shoe 12.

Lower section 14 is formed from a flexible, semi-rigid material, and is provided with a number of anti-slip features 20, which increase traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. For overshoe 80, anti-slip features 20 comprise small studs 20d, large studs arranged in clusters 20e and a raised chevron 20f. In FIG. 3B it is seen that anti-slip features 20 are spaced apart, allowing overshoe 80 to be easily rolled into a compact form.

As seen in FIG. 3A attached to heel section 24 of lower section 14 of overshoe 80 is a back section 28 of upper section 18 of overshoe 80. Unlike overshoes 10 and 50, back section 28 of overshoe 80 is not a strap but rather a relatively broad flexible curved sheet of material configured to wrap around the heel of a shoe over which overshoe 80 is placed. Such wrapping around holds the shoe tightly associated with overshoe 80 and protects the heel of a shoe from exposure to the elements.

As seen in FIG. 3A attached to the front part of lower section 14 of overshoe 80 is a toe section 32 of upper section 18 of overshoe 80. Integrally formed with toe section 32 and constituting an integrally formed continuation thereof is vamp section 36. Unlike overshoes 10 and 50, toe section 32 of overshoe 80 is not a strap but rather a flexible curved sheet of material configured to wrap around the toe of a shoe over which overshoe 80 is placed. Such wrapping protects the toe of a shoe from exposure to the elements. Further unlike overshoes 10 and 50, vamp section 36 of overshoe 80 is not a strap but rather a relatively flexible curved sheet of material configured to lay over and entirely cover a lace or zipper portion of a shoe over which overshoe 80 is placed. In such a way, vamp section 36 prevents entry of water and snow into a shoe through the lace or sipper and also protects the vamp of a shoe from exposure to the elements.

To ensure that vamp section 36 is held tightly against a shoe, overshoe 80 is provided with two straps on each side. Strap 82 (a similar strap is found on the non depicted side of overshoe 80) is an elastic strap that ensures that the lower and middle portions of vamp section 36 are held tightly against a shoe. Openable strap 84 (a similar strap is found on the non depicted side of overshoe 80) is an adjustable strap provided with a fastening feature 44 (as described above) that allows easy wearing of overshoe 80 over a shoe and ensures that the upper portion of vamp section 36 and heel portion 28 are held tightly against a shoe.

FIGS. 4A to 4C depict an alternative embodiment 60 of the overshoe of the present invention, which provides substantially complete coverage of the shoe or other item of footwear, therefore affording protection of the footwear, as described above, in addition to reduction or prevention of slippage of the user. As shown in FIG. 4A, the lower section of overshoe 60 comprises an undersole 62, configured to fit under the sole of an item of footwear, a toe portion 64, configured so as to fit over the toe of an item of footwear, a back portion 66, configured to fit over the back and heel of an item of footwear, and a closable vamp portion 68, comprising a pair of flaps 70. In a first configuration as depicted in FIG. 4A, flaps 70 are spread apart for easy insertion and removal of worn footwear into and from overshoe 60. Once footwear is positioned inside overshoe 60, flaps 70 are folded over and secured in a second configuration as depicted in FIG. 4B, so that the footwear is tightly associated with overshoe 60 in accordance with the teachings of the present invention. In addition, the footwear is substantially entirely surrounded by and enclosed within overshoe 60 so as to protect the footwear from contact with damaging materials.

Flaps 70 are secured, as shown in FIG. 4B, using any suitable fastening device, such as any of the fastening devices discussed above. Specifically, in FIGS. 4A and 4B, flaps 70 are provided with strips of standard hook and loop fastener material, often used in the art of shoemaking.

As with overshoes 10 and 50 depicted above, the lower section of overshoe 60, undersole 62, is provided with at least one anti-slip feature 20, which increases traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. Anti-slip features 20 of overshoe 60 consist of a plurality of raised chevrons. In overshoe 60 anti-slip features 20 are distributed in such a way (with a sufficiently large separation) as to provide good traction but also to not interfere with folding or rolling of overshoe 60, enabling overshoe 60 to be stored in a compact form.

In addition to anti-slip features 20, proximal to the front of the lower section of overshoe 60, undersole 62, is sharp feature 76. Sharp feature 76 is configured to dig into packed snow when a user takes a forward step and thus give a user an added measure of traction for forward motion.

The upper surface of undersole 62 of overshoe 60 is provided with at least one anti-slip feature configured to frictionally engage footwear held inside overshoe 60 so as to prevent slippage of the footwear and thus provide a user with more stability. Specifically, the internal anti-slip features of overshoe 60 are protrusions 72.

As is clear to one skilled in the art upon perusal of the description, addition to protecting the wearer against slippage, overshoe 60 protects the footwear from becoming wet or soiled when walking on icy, snowy or wet surfaces, which is particularly useful for people who do not wish to carry a spare pair of footwear such as shoes or boots for traveling under such conditions, but still wish to arrive at their destination with their footwear dry, intact, and unsoiled.

Any of the embodiments of the present invention described above may preferably be formed of a lightweight, waterproof material, having sufficient elasticity and durability for the purposes of the present invention, and which may be rolled into a compact form for easy and convenient storage and transport, such as any suitable natural or synthetic elastic polymer or co-polymer. Non-limiting examples of suitable materials include natural rubber, polyisoprene, polybutadiene, polychloroprene, silicone, polyurethane rubber, polyacrylic rubber, epichlorohydrin rubber, polysulfide rubber, and the like.

The overshoe may optionally be provided in a variety of colors, and/or include additional decorative features, for aesthetic and commercial purposes.

It is expected that during the life of this patent many relevant overshoes will be developed and the scope of the term overshoe is intended to include all such new technologies a priori.

As used herein the term “about” refers to ±10%.

Additional objects, advantages, and novel features of the present invention will become apparent to one ordinarily skilled in the art upon examination of the following examples, which are not intended to be limiting. Additionally, each of the various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below finds experimental support in the following examples.
